What is the essence of the double kidney problem? What is a double kidney and why is it dangerous? Echo signs of doubling of the left kidney

Sometimes doctors observe kidney doubling, which is diagnosed in the fetus during intrauterine development. If there is a violation, an anomaly occurs in the development of the pyelocaliceal system, resulting in complete or partial division of the kidney. Moreover, each lobe of the organ has its own blood supply system. More often, pathology of one kidney is diagnosed, less often two are affected. Such an abnormal structure of the internal organ can threaten impaired urinary function. When doubling, therapeutic measures aimed at eliminating secondary infections are required. In particularly difficult situations, surgical procedures are prescribed.

Kidney duplication is a congenital pathology that can slightly or significantly affect the functionality of the organ.

What structure do healthy kidneys have?

The kidneys are a paired organ that is divided into two lobules. There is adipose and connective tissue around the organ, which prevents injury and damage. and the gate is located in the concave part of the organ. Also, 2 ureters depart from each kidney, through which urine enters the bladder. The lobes of both kidneys are separated blood vessels. If for some reason anomalies occur during intrauterine development, then a doubling of the child’s kidney is noted. Doubling also often occurs.

A person develops various reasons having an innate character. The splitting of a healthy organ occurs during intrauterine development. The doubling of an organ on one or both sides is influenced by the following negative sources:

Kidney duplication occurs in utero under the influence of hormones, radiation, and genetic abnormalities.

hormone therapy during pregnancy;
lack of vitamins and minerals during intrauterine development;
ionizing radiation;
drug intoxication;
smoking and drinking alcohol while pregnant.

Extra kidneys in children can occur if at least one of the parents suffered from such an illness. In this case, complete or incomplete doubling of the kidney on the right or left side is possible. According to statistics, renal twinning is more often recorded in the fairer sex. Doctors have not been able to fully figure out why women are more likely to suffer from doubling.

What happens when a full doubling occurs?

With complete doubling, two organs are formed at once. In rare cases, pathology is observed on both sides. Each double kidney has its own pelvicalyceal system. Sometimes one of the CHLS systems is undeveloped in to the fullest. Complete kidney doubling does not require surgical therapy provided that the urinary excretion process is not impaired. With such an anomaly, it is important to carefully monitor your health and be regularly examined by a nephrologist.

Incomplete doubling: the essence of the problem

Often, incompletely doubled buds are diagnosed, in which case incomplete doubling is noted. The disorder is characterized by the presence of one ureter, through which urine exits into the bladder. In rare cases, doctors observe the entry of the ureter of the double kidney into the vagina or intestines. With this disorder, urine may exit through the posterior opening or leak through the vagina.

Incomplete doubling kidneys are more common, but this problem is in no way inferior to complete double birth.

Incomplete duplication of the left kidney is diagnosed much more often, while in the process of intrauterine development 2 rudiments of metanephrogenic blastoma are formed, which soon form 2 internal organ urinary
The following morphology of incomplete organ duplication is distinguished:
preservation of the joint capsule of daughter neoplasms;
supplying each half of the organ with its own circulatory system;
separation of the renal arteries in the renal sinus or the vessels arise directly from the aorta.

What are the dangers of a double kidney?
Duplication of a kidney on the right or left side entails Negative consequences. Complications are most likely to develop with incomplete doubling, since in this case urodynamics are significantly impaired. Patients with duplication of the right or left kidney suffer from the following complications:
inflammatory process in a paired organ;
stone formation;
hydronephrosis;
tuberculosis lesions;
nephroptosis;
malignant or benign neoplasms.

If the patient also has vesicoureteral reflux, then the likelihood of an inflammatory reaction against the background of doubling increases significantly. Complications may progress long years, disrupting the function of many systems in the body. Such violations are difficult to overcome therapeutic measures and often bring only short-term results.
What signs indicate illness?
If complete bifurcation is noted, then the signs, as a rule, are absent or do not appear clearly enough. When the ureter is removed into the vaginal area, the patient exhibits signs of a different nature. Urine leakage is often seen, which occurs in adults and children. Doubling can be detected by the following pathological signs:
swelling of the limbs and face;
general weakness;
pain in the lower back;
cloudy urine;
high temperature and pressure;
pain when passing urine;
feeling of nausea and vomiting;
renal colic.

What to do?

Importance of diagnosis

Kidney duplication is clearly diagnosed by hardware examination.
It is almost impossible to identify a bifurcated kidney on your own, even if the patient’s urinary process is disrupted, this can be mistaken for an inflammatory process in the organ, and not an abnormal structure. To detect pathology, you need to see a doctor and conduct a comprehensive diagnosis. Most often, doubling is accidentally detected on ultrasound during examination of other organs. When diagnosing, the following are used diagnostic methods given in the table.
With the help of complex diagnostics, it is possible to identify organ growth, determine secondary pathologies and the degree of disorder. Diagnostics also allows you to select the most accurate therapy.

Among many possible deviations Kidney doubling is very common. It can arise due to various factors.

This pathology is detected in 1 child out of 150 births, and these are often girls. When diagnosed, children are found to have a kidney that is several times higher than natural values.

The lower part is larger than the upper part. The embryonic lobulation of such an organ also differs. Each lobe has its own arteries through which blood moves.

general characteristics

Double kidney is a congenital disease. It has complete or incomplete duplication of the kidney. A similar defect develops while still in the womb.

Externally, the organ looks like two equivalent kidneys. The organ performs the most important task - it cleanses the blood and removes toxins and other unwanted components from the body.

Duplication of the right or left kidney is certainly an anomaly, but it is not considered a dangerous disease.

It happens that a person is not even aware of the problem and lives calmly for the rest of his life.

Sometimes, however, such an abnormality of the organ leads to other diseases. In this case, the patient develops unpleasant signs that begin to cause discomfort to the person, and then specialists must intervene.

Kinds

A similar defect, such as doubling of the right or left kidney, is detected in two varieties.

Classification:

Complete split. In this case, the kidney has 2 equal parts connected into one cavity. All these lobes have an independent structure, that is, they have a separate artery with a blood supply and a central joint.
Incomplete doubling of the kidney. This type is characterized by the presence of one CLS for 2 lobules. Very often, incomplete doubling of the kidney is observed on the left side. The renal element is located in the tissue of the other lobe. The kidney itself is quite larger than normal. Both ureters are connected by a single outlet.

What factors influence the development of kidney defect in a baby?

Pathology may not manifest itself at all. Most often this occurs if there is incomplete duplication of the kidney.

It happens that an anomaly is diagnosed completely by accident in an adult, during some kind of examination. Most effective method diagnostics in this case is ultrasound.

There are enough reasons for the development of the defect. Babies are diagnosed with a birth defect for reasons related to:

Heredity. If such an anomaly was previously diagnosed in a family member, then it is likely that the child will be born with the same abnormality.
Drug intoxication. If a pregnant woman experiences drug poisoning, the likelihood of kidney doubling increases.
Radioactive exposure. This happens if the expectant mother was often in a place of constant exposure. This is possible if a woman works in any enterprise with radiation exposure.
Using alcohol, cigarettes or drugs.
Strong development of vitamin deficiency. Even a lack of vitamins and minerals can affect the condition and development of the body.
Bacterial or infectious diseases.
Frequent use of hormonal drugs.

Any of these reasons can cause the organ to become deformed during formation and lead to doubling.

CHLS: description

An important part in the structure of the entire kidney. It has the shape of a funnel, obtained as a result of the separation of 2 cups of the organ.

It is in the pelvis that all urine is located. Inside, it is lined with a special mucous membrane, which prevents fluid from escaping into the abdominal cavity.

Its main function is to contract and push urine out through the drainage pipes.

Signs

Bifurcation of the kidney, as such, occurs without any special symptoms. In some cases, an intrauterine anomaly is detected completely by accident.

Some people live with this diagnosis and do not even know they have it. And everything would be fine, but sometimes such a defect can cause other diseases that have their own symptoms.

In this case, the signs may vary differently for each patient. General list of signs:

Hydronephrosis. The pelvis is stretched and disruptions occur in contractile work. This condition causes disturbances associated with urine excretion.
Very often the body suffers from inflammatory outbreaks. However, they are prone to relapse.
Urine through the ducts should only go down to the outlet. If there are any failures in the structure, its reverse flow is noted.
High body temperature.
The person may have difficulty urinating.
Pain in the back area where the kidneys are located.
General malaise.
High blood pressure.
Incontinence.
Renal colic may appear.
Edema.

These symptoms are among the most common. Depending on the complications, the list may decrease or expand.

Each organism is individual, therefore both the course of diseases and their symptoms vary.

What does congenital pathology lead to?

When doubling, one of the lobes may be susceptible to some disease. With complete doubling, pathologies such as:

Nephrosis.
Pyelonephritis.
Polycystic disease.

Sometimes it happens that the urinary conductor does not flow into the ureter, but into another organ. In this case, the patient constantly feels urine leaking. The mouth can flow into the vagina, cervix or rectum.

It should be noted that diseases of the urinary tract located at the top are very difficult to treat, and the course is very severe.

Any antibacterial treatment gives only a temporary effect. Thus, people who are diagnosed with duplication of the left or right kidney are more likely than others to suffer from diseases with chronic development.

Periodically, patients experience exacerbations. Experts again prescribe antibacterial therapy.

Pregnancy

A woman with such a diagnosis does not need to be upset. A bifurcated kidney is not a contraindication to pregnancy.

The important point is preparation. Without such an approach, experts do not advise taking risks.

Before starting to plan a future pregnancy, a woman must undergo all prescribed examinations.

If there are foci of inflammation or infectious diseases, the patient must first take all necessary measures to sanitize them.

Throughout the pregnancy, the expectant mother is observed by a therapist and gynecologist. They may also be periodically referred for consultation to a urologist or nephrologist.

If there is an increased likelihood of developing any diseases, the woman will be sent to a hospital, where she will be observed and carried out all necessary treatment for normal gestation.

Over the entire period, the expectant mother may be hospitalized several times.

Diagnostic measures

If the anomaly was not detected in the child, then in the future it may not be detected at all.

That is, some factor must contribute to diagnostic measures. When a patient begins to complain of diseases of the urinary system, examination methods are prescribed to identify the cause.

Only in this case, random diagnosis can reveal congenital pathology.

To diagnose a kidney abnormality, doctors prescribe instrumental examination. This may include:

MRI. Shows in 3-dimensional projection the structure and condition of the CLS.
Cystoscopy. Allows you to visually examine all existing ureteral orifices.
Echography with color Doppler mapping. Detects the existence of independent CLSs. Also using this method you can find out about their condition.
Excretory urography. With this method it becomes possible to estimate general state ureters, as well as identify the presence of dilations and bifurcations of the pyelocaliceal system.

Very often, in a person with this development of anomaly, the entire urinary system suffers.

To recognize lesions, the presence of complications and the neglect of other diseases, a series of additional examinations carried out in the laboratory.

Blood chemistry.
General urine analysis.
Bacteriological culture.
A smear from the urethra is also taken for bacterial analysis.

Preventive measures

It is impossible to turn back time and change nature too. The expectant mother is forced to become familiar with the possible factors in the development of the anomaly in advance and try to eliminate them as much as possible.

If this does happen, and the child was born with a similar renal anomaly, then from childhood he needs to be taught the need to follow simple measures that will help minimize the risk of complications in the future.

How to live with a double kidney? First of all, a person should not acquire bad habits.

Their harmful effects will contribute to the development of possible inflammation. Workplace It is advisable to choose the most calm and comfortable one.

These should not be cold rooms or enterprises associated with toxic chemical components.

Nutrition will also play a major role. The most healthy and balanced food helps to eliminate many diseases associated with both the urinary system and other organs throughout the body.

Work and rest schedules need to be properly planned. Heavy physical work is not recommended with this diagnosis.

Since abnormal development of the kidney can occur due to a genetic predisposition, in such a family future pregnancy must be taken care of in advance.

When carrying a child, a woman needs useful minerals and various vitamins. And, of course, it is necessary to exclude all factors causing such development.

Therapeutic methods

As long as the renal anomaly does not manifest itself in any way and does not affect the quality of life, there should be no talk of any treatment.

The only important condition is periodic examination. This will allow you to eliminate the risk of consequences in time and carry out the necessary treatment at the first inflammatory processes.

As a preventative measure, the use of herbal medicines and diuretics may be prescribed.

Any other treatment will be prescribed according to a particular problem. If complications arise, then most often specialists prescribe therapy using:

Antispasmodic or analgesic drugs. This is necessary when pain is present.
General purpose antibiotics.
Kidney teas.
Folk recipes based on natural ingredients. These can be either herbal mixtures or individual herbs.

In severe cases of pathology, a specialist may recommend surgery. The indications are:

Vesico-ureteral reflux.
Chronic pyelonephritis with constant recurrent effects.
Destruction of the kidney (abnormal, functional) and its segments.

The operation is carried out in several types. It could be:

Transplanting a new one healthy kidney. This operation is indicated if severe renal failure occurs.
Nephrectomy. Conduct complete removal if separation is impossible, or only the affected part is excised.
Excision of ureterocele. Subsequently, interrupted sutures are applied, and the ureter is sutured to the walls of the bladder.
Antireflux surgery. Involves the creation of artificial lumens for the passage of urine.

Conclusion

Duplication of the left or right kidney is not a serious pathology and by itself it does not manifest itself in any way.

In this case, one of the lobes, often the upper one, is subject to inflammatory processes.

To prevent the appearance of other diseases, a person needs to get as close as possible to a healthy lifestyle and eliminate all negative factors.

Important! Some people live with this anomaly from birth, and it does not affect their quality of life in any way. Treatment may be needed only if serious consequences occur due to bifurcation.

Useful video

Of the anomalies in kidney development, duplication of these organs is the most common. More often, the problem is observed in girls on one side of the body, but sometimes it occurs on both sides.

Kidney duplication - what is it?

Modern medicine recognizes kidney duplication as a congenital pathology in which there is a complete or partial duplication of the renal system. The anomaly accounts for more than 10% of all defects of the urinary system, occurs in approximately 150 cases of post-mortem autopsy, and in newborns - in 1 case out of 140 children born. Unilateral doubling accounts for 88% of all registered pathologies, doubling of both kidneys accounts for 12%. The ICD-10 code is Q63.8 (Other congenital anomalies of the kidney).

When doubling, the kidney visually looks like two organs, each with its own blood supply.

An abnormal kidney, of course, has a significant big sizes than normal. The double kidney itself does not cause physical problems or serious impairment of the system’s function, but it contributes to the development of a number of diseases throughout life.

Causes

The pathology can be exclusively congenital; it begins during the period of intrauterine development of the fetus. Hereditary disposition is often important when one of the parents and close relatives has a similar anomaly. Also, a number of factors can have a pathogenic effect on the body of the mother and fetus, as a result of which a kidney with structural defects is formed during embryogenesis.

Among these factors are:

Receiving radioactive and x-ray irradiation.
Work in hazardous industries.
Poisoning with drugs, poisons, intoxication.
Taking drugs with teratogenic effects.
Severe vitamin deficiency.

The result of the action of such factors is the appearance of two foci of kidney growth, when 2 pyelocaliceal systems are formed. Their final separation does not happen, so the double kidney is covered with a common fibrous membrane. The vessels depart separately from the aorta, or have a common trunk, which is then divided into two parts and approaches each kidney individually. Sometimes the arteries inside the double kidney penetrate from one abnormal organ to another, which can create certain difficulties during surgery.
In the video about what kidney doubling is like:

Forms of pathology

As already noted, the anomaly can be one-sided or two-sided.

But in medical practice great importance There is also a differentiation of pathology into the following forms:

Full doubling. Both the left and right kidneys have their own ureter, their own pyelocalyceal system. The pelvis is located parallel, connected only by a small isthmus of connective tissue. The calyx that is located at the top, as a rule, is underdeveloped, and the lower pelvis functions fully. Each of the doubled kidneys is, in fact, a separate organ.
Incomplete doubling. With this anomaly, the parenchyma of the organ is double, its vessels are also doubled. The pyelocaliceal system develops without duplication. The top of the abnormal kidney is smaller than the bottom.

The most common occurrence is incomplete duplication of the left kidney. The right organ is affected much less frequently. The underdeveloped part of the double kidney resembles the state of the organ during dysplasia.

The photo shows the form of kidney doubling

Symptoms

Manifestations of incomplete kidney duplication in a newborn and in people throughout life are usually absent. Sometimes a person is not even aware of the existing anomaly, and finds out about it by accident. Incomplete doubling does not cause any consequences for life or a decrease in its quality.

Complete doubling also does not lead to the appearance of symptoms, but only until various complications are superimposed on it. This can occur at any age, but is less commonly diagnosed in children under 8-10 years of age.

Usually, with long-term existence of anomalies without surgery, the following are observed:

Regular inflammation;
Hydronephrosis with accumulation of urine in the pelvis;
Backflow of urine from the ureters.

Symptoms of complete kidney duplication may include:

Pain in the lower back;
Pain when tapping on the lower back;
Sometimes - increased body temperature;
Edema;
Weakness;
Frequent renal colic;
Arterial hypertension;
Pain when urinating;
Occasionally – urinary incontinence.

The infection can spread downward to the bladder and urethra with the appearance of a characteristic clinical picture of cystitis and urethritis.

Diagnostics

Typically, anomaly detection occurs as planned. Thanks to mandatory screening in children under one year of age, kidney duplication is often detected in a child already on an ultrasound at 1-6 months. Thus, renal ultrasound is the main diagnostic method that suggests this anomaly.

X-ray, MRI, CT. Allows you to examine in detail the shape and structure of the kidneys.
Excretory urography. Helps to see the ureters, expansion and duplication of the pyelocaliceal system.
Doppler scanning. Used to evaluate the vessels supplying the kidneys.
Cystoscopy. The specialist visualizes the orifices of the ureters, their number and location.

Inflammatory changes in the urinary system and the effectiveness of its work are confirmed by tests. Applicable:

General urine analysis;
Urinalysis;
"Kidney" blood biochemistry;
Analysis of a smear from the urethra for bacterial culture, etc.

Often, an experienced specialist can assume the presence of kidney duplication in the fetus during pregnancy. An ultrasound at 25 weeks and later may well provide the necessary information. Separately, it is necessary to say about pregnancy with a double kidney. Such women must be carefully monitored by a nephrologist and urologist throughout the entire gestation period; they regularly undergo a series of laboratory and instrumental tests. In the presence of renal failure, indications for surgery, pregnancy is contraindicated.

Treatment and prognosis

There is no specific conservative treatment for this anomaly. But because increased risk development of various complications, it is important to exercise dynamic control over the health of a person with a double kidney. As a preventive measure, they take diuretics, herbal remedies and other drugs prescribed by a specialist, and also regularly donate urine and perform an ultrasound of the kidney. A diet with a reduced amount of salt, spicy foods, smoked foods and other foods that can cause kidney overload is important. You should definitely stop smoking and drink alcohol in minimal quantities.

If complications occur, treatment is symptomatic and pathogenetic.

Spicy and chronic inflammation and impaired urinary outflow are treated by taking:

Antibiotics;
Antispasmodics and painkillers;
Herbal preparations (kidney tea, corn silk, lingonberries, cranberries, etc.).

In the presence of a severe, often aggravated chronic pyelonephritis, as well as severe vesicoureteral reflux should be planned surgery. Also, one half of the kidney or the ureter is removed in case of stones, hydronephrosis, or lack of organ functioning, and the operation (heminephrectomy) is performed at any age. The appearance of a tumor or the lack of technical ability to separate the kidneys becomes an indication for complete nephrectomy. Kidney failure will require a kidney transplant from a donor or hemodialysis.
In the video about the causes and treatment of kidney development abnormalities:

What is the threat?

A prerequisite for the development of complications is the presence of renal dysplasia and urodynamic disturbances due to a double ureter. As a result, in the underdeveloped part of the kidney, incomplete emptying of the pelvis is observed, urine stagnates, which causes various diseases.

The most common inflammation of the kidney is pyelonephritis, which is especially common with complete doubling, combined with ectopia of the ureteral orifice, ureteral reflux, cystic reflux, and uregerocele. Pyelonephritis is observed in 24% of doubling cases.

Other possible consequences:

Kidney stones – 21%;
Hydronephrosis – 14%;
Nephroptosis – 3%;
Kidney tuberculosis – 36%;
Tumors – 2%.

A kidney with an anomaly is very vulnerable; moreover, the infectious process in it often spreads to a healthy organ. Therefore, it is important for the patient not to overcool, eat right, and immediately treat all inflammations and infections in order to maintain health at a high level.

Nowadays, the concept of incomplete doubling of the kidney is quite common. This term describes one of the forms of abnormal development of one of the organs of the pyelocaliceal urinary system. Doctors do not consider this a disease, since it does not have a distinct pronounced signs, but such a pathology makes the patient quite vulnerable and prone to various inflammatory diseases that have chronic features.

Return to contents

Doctors often do not classify this kidney disease as dangerous and do not make a special clinical conclusion about this. But when the pyelocaliceal system and ureters are doubled, dangerous situation for the patient. Therefore, to clarify all clinical picture excretory type urography may be prescribed.

General information

The abnormal structure of the kidneys begins in the prenatal period. According to statistics, one out of 150 newborns has a double organ. Girls are at risk for developing the disease; in boys, the diagnosis is confirmed 2 times less often. Duplication on one side occurs in 89% of cases, and for unclear reasons, duplication of the right kidney is more often diagnosed. Anomaly on both sides occurs in 11% of cases.

Visually, the duplicated organ differs from a healthy one and looks like two kidneys fused at the poles, each with its own blood supply. Despite the irregular structure, the doubled organ performs the main functions of purifying the blood and excreting harmful substances from the body.

Classification

In addition to one- and two-sided doubling, pathology is classified according to forms:

complete doubling is a type of abnormal kidney in which the organ is presented in the form of 2 independent structures connected into one whole; from an anatomical point of view, the structure of the kidney with complete doubling is organized as in 2 separate organs - both elements have their own blood supply system, characterized by the presence of doubling of the renal system of the kidney (pyelocaliceal system);
incomplete doubling of the kidney is a type of anomaly when one renal element is integrated into the tissue of another; a characteristic feature of this form is associated with the presence of a single CLS; with incomplete doubling, the organ greatly increases in size; Incomplete duplication of the left kidney is more often diagnosed.

Pathogenesis

In medicine, there is no accurate information about the causes of the disease. Of no small importance is given hereditary factor- if one of the parents or other close relatives is diagnosed, the likelihood of an anomaly increases. Other significant reason associated with the impact on female body During pregnancy, negative factors such as:

ionizing radiation;
working in hazardous conditions;
past bacterial and viral infections;
drug intoxication, poisoning;
taking hormonal medications;
intake of alcohol and nicotine;
severe forms of hypovitaminosis.

As a result, two foci of kidney growth appear in the developing embryo, and conditions are created for the development of two buds. Complete separation of the CL does not occur; the doubled kidney is covered with a common fibrous layer. Occasionally, in an abnormal organ, vessels intertwine, penetrating from one element to another, which complicates the possibility of performing operations in the future.

Symptoms

People with double kidneys usually do not have negative symptoms. Confirmation of the diagnosis occurs by chance, during examination for other diseases. Negative symptoms become clinically significant only when complications occur. With complete doubling, complications are more serious than with incomplete doubling. In both cases, over a long period of time, anomalies arise:

frequent, recurrent inflammatory processes;
hydronephrosis - a condition in which the renal pelvis dilates and urine excretion is impaired;
backflow of urine from the ureters.

Additionally, the presence of an anomaly may be indicated by:

aching pain in the lumbar area;
pain when tapping the lower back;
rise in temperature;
attacks of renal colic;
difficulty urinating;
urinary incontinence;
weakness;
increased blood pressure;
swelling of the face and limbs.

Survey tactics

To confirm the diagnosis, instrumental studies are organized:

echography with color Doppler mapping is a method that allows you to identify the presence and assess the condition of independent CLS;
cystoscopy - necessary to visualize the orifices of the ureters, their number and location;
excretory urography is a method that allows you to assess the condition of the ureters, the presence of dilations and doublings of the urinary tract;
MRI will allow you to reliably examine the pyelocalyceal system in a three-dimensional projection.

Laboratory diagnostics are carried out to identify inflammatory processes in the urinary organs and assessing the effectiveness of their work. For this use:

general urine analysis;
bacteriological culture;
biochemical blood test with determination of the concentration of creatinine, urea, albumin, uric acid, ions (potassium, chlorine, sodium);
smear from the urethra for bacterial analysis.

Treatment

There are no specific methods for treating the pathology. But patients with organ duplication are subject to systematic observation and examination to monitor the functioning of the renal system. For preventive purposes, diuretics and herbal medicines are prescribed. If complications develop, therapy is symptomatic:

taking antibiotics wide range actions;
antispasmodic and painkillers;
balanced diet with limited salt and fat;
taking special kidney teas.

Surgical intervention for anomalies of the renal system is carried out for a number of indications:

chronic recurrent pyelonephritis;
vesico-ureteral reflux;
functional or anatomical destruction of an organ and its segments.

Types of surgical interventions:

nephrectomy - excision of the affected renal segments; if complications arise in the form of a tumor and it is impossible to separate the kidneys, a complete nephrectomy is performed;
antireflux surgery - creation of artificial lumens for the free flow of urine;
excision of ureterocele with interrupted sutures and suturing of the ureters to the walls of the bladder;
Kidney transplantation and hemodialysis are indicated if acute failure kidneys against the background of doubling.

The course of pregnancy with pathology

A woman with a double kidney can become a mother - the pathology is not a contraindication to pregnancy. The only contraindication is considered to be a severe course of the anomaly with the need for surgical intervention, or renal failure that has arisen against the background of doubling. Preparation for pregnancy should be thorough, with comprehensive examination and treatment (if necessary) of detected foci of infection.

A possible risk for a pregnant woman is associated with compression of the abnormal kidney by the growing uterus and disruption of its filtering ability. Therefore, throughout the entire gestation period, a woman should be observed not only by a gynecologist and therapist, but also by a nephrologist (at least once every 2 months). If complications arise from the renal system, the pregnant woman must be hospitalized in the urology department to correct the condition.

Preventive measures

There are no specific preventive measures, which is due to the mechanism of formation of the anomaly at the genetic level. A responsible approach to pregnancy planning can reduce the likelihood of developing pathology and healthy image life of the expectant mother. Proper nutrition, taking multivitamin complexes and following medical recommendations allows you to maintain your own health and ensure adequate formation of organs in the fetus.

Persons with a confirmed diagnosis of kidney duplication should follow basic preventive measures:

optimal drinking regimen, no more than 1.5 liters of liquid per day;
rational nutrition with limitation of salty, bitter, spicy foods;
moderate physical activity;
hardening;
avoiding hypothermia.

If an abnormality of the heart rate is detected, an adult should stop drinking alcohol and smoking - alcohol and nicotine negatively affect the renal system, undermining its function.

Kidney duplication is an anomaly in which negative manifestations may be absent throughout life. It is important to understand that an illness can become a prerequisite for the development of other, more serious diseases. With a responsible attitude to health, the life expectancy of persons with a double kidney is identical to that of healthy people.

Double kidneys. What it is?

The kidneys in the human body are a paired organ. They perform the function of removing toxins from the body. Everyone knows about this. But not everyone has heard that kidney doubling occurs. What it is? This is the division of an organ into two halves, fused at the poles. Each part is equipped with its own blood supply system. Externally, such a kidney is much larger in size. The development of pathology occurs during intrauterine development.

Double kidneys in children are the most common congenital anomaly of the urinary system. An altered kidney does not pose a threat to human life, but is often the cause of other diseases.

The structure of the renal pelvis

This funnel-shaped structure is formed by the fusion of the major and minor calyces of the kidney. It is in the pelvis that urine accumulates. The surface of the inner part of the pelvis is covered with mucous membrane. In the wall of the pelvis there are fibers that perform peristaltic contractions, as a result of which urine flows down the urinary tract down.

Due to the impermeability of the walls of the pelvis and ureters, the liquid with the substances dissolved in it never enters the peritoneal cavity, but always remains within the urinary system.

Complete kidney doubling

Sometimes a person is diagnosed with complete kidney duplication. What it is? This is an abnormal phenomenon when the kidney is divided into two parts by a groove. The upper and lower lobules are distinguished, and the upper one is most often underdeveloped and smaller in size. Each of them has its own artery and its own renal pelvis, which is usually underdeveloped in the upper half. They also have their own ureters. Each goes separately and ends in the bladder with its own mouth. It is possible that one ureter flows into another.

So, instead of one, there are two separate buds. In itself, complete doubling of the kidney does not bother a person, so there is no need to treat it. But it leads to other diseases.

Problems that arise when a kidney doubles

Often, some kind of disease may begin to develop in one half of the doubled organ. Complete doubling of the kidney can provoke pyelonephritis, urolithiasis, nephrosis, polycystic disease. It happens that the mouth does not flow into the ureter, but into some other organ. It can be the rectum, cervix, vagina. In this case, a person may feel urine constantly leaking from the ureter.

This pathology is observed when a person develops one large kidney with clearly defined upper and lower sections. Each of them has its own renal artery. N, each part of the doubled organ does not have its own pyelocaliceal system; they have one for two sections. There are two ureters, but they are connected to each other and flow into the bladder with a single trunk, like one.

In medical practice, cases have been recorded where incomplete doubling of the left kidney is more often observed, rather than the right. Most people with this anomaly live until old age, unaware of its existence. Incomplete doubling of the kidney does not cause inflammatory processes in the organ.

Causes of kidney duplication

If the pathology does not manifest itself in any way, which happens when a person has incomplete duplication of the left or right kidney, it does not matter, you may not even know about the abnormal development of this organ. It is discovered by chance, during an ultrasound examination of some other organ located next to the kidney. Doctors often diagnose a double kidney in a newborn child. The reasons for this phenomenon can be very different. Let's look at some of them:

Radioactive exposure of the fetus in the womb, if her work activity during the entire period of pregnancy takes place at an enterprise whose production cycle is associated with radiation.
The predisposition is inherited if one or both parents have a double kidney. What it is is described above in this article.
Poisoning with drugs during pregnancy, including hormonal drugs.

Availability bad habits in a pregnant woman: abuse of alcohol, drugs, etc.
Vitamin deficiency occurs frequently and regularly during pregnancy. There are many places on our planet where vegetables and fruits do not grow due to harsh climates. climatic conditions. But women live and give birth to children there too. So he suffers future mom lack of vitamins and useful minerals. It’s good if everything works out and the child does not have a disease such as kidney duplication. Of course, there may be other reasons, but this one can be ruled out for the sake of the health of the unborn baby.

Diagnostics

If no testing was done when the person was a child, kidney duplication is diagnosed, usually after it begins inflammatory disease organ or accidentally, during a preventive examination using diagnostic devices. First you need to do an ultrasound examination. If this is not enough, the doctor prescribes other methods.

When a person does not have pathology, there are only two ureteric orifices in his body: one for each kidney. If the doctor suspects kidney duplication, the patient is prescribed a cystoscopy. With its help, it is determined how many orifices the ureter has: if there are three, then the diagnosis of “double kidney” is confirmed. To determine the size of the enlarged kidney and identify the presence or absence of the third calyceal pelvis and additional ureter, the doctor prescribes excretory urography.

Symptoms

Kidney duplication does not manifest itself in any way. It does not need to be treated until it causes some other disease in this organ. Signs of kidney duplication vary. Typically, inflammatory processes are characterized by:

Increasing temperature.
Weakness and swelling.
Nausea and vomiting.
Regular headaches.
Increased pressure.
Cloudy urine.
Reverse flow of urine.
Discomfort and pain in the lumbar region.
Urinary incontinence.
Unpleasant sensations when urinating.
Renal colic.
The occurrence of infection in the urinary canal.

Whether all signs appear at once or each one separately will depend on the disease.

Treatment

Kidney duplication is characterized by complete or incomplete division of the organ into two parts. If it doesn't bother the person, nothing needs to be done. It is enough to lead a healthy lifestyle and undergo regular preventive examinations. This pathology provokes inflammatory processes in the kidney when it completely doubles. Even in this case there is no point in doing complex operation to correct the defect. It may not cause trouble to a person throughout his life.

Therapeutic treatment is usually used when diagnosing some serious disease, for example, pyelonephritis, if it was caused by this anomaly. When the disease progresses to chronic form and cannot be treated with conservative methods, then resort to surgical intervention, which is aimed at correcting the cause that caused the complication. But they always try to save the kidney. It is removed only when it has completely lost its functionality.

Prevention

If during the examination a doubling of the kidney is discovered, there is no need to panic. This diagnosis is not fatal. When the pathology of an organ does not bother you, it will not affect a person’s quality of life in any way. You need to take a closer look at your health:

Give up bad habits, if any: stop drinking, smoking, taking drugs.
Change your job if it involves toxic chemicals.
Urgently switch to a properly balanced diet.
Strictly monitor the work and rest schedule.

If one of your relatives has a doubling of the kidney, what it is is known to the whole family. Therefore, when a woman from your family is bearing a child, you need to treat this period with double attention. The child in the womb must develop, receiving essential vitamins. A woman must take care of her health and not take alcohol, drugs, medications which can cause poisoning to a child.

Causes of the anomaly

Doubling of the heart rate of the right kidney - what is it? Surprisingly, this question began to appear quite often. This is due to the spread of an unusual pathology. Incomplete duplication or duplication of one of the kidneys is the first stage of such an anomaly. It can occur during the development and formation of the fetus in the womb.

Due to the influence of various factors on a pregnant woman or if the parents have altered genes during the formation of the urinary system, specific abnormalities may develop (doubling of the left kidney).

Among the factors influencing intrauterine development, there are several main ones:

various types of ionizing radiation;
lack of vitamins and essential minerals;
use of certain medications;
bad habits: alcohol and smoking.

The disease can develop in two directions:

the kidney has two pelvises, which are supplied by one artery;
the excretory organ is equipped with two arteries and one pelvis, while the arteries have separate exits from the aorta.

Basic concepts of partial doubling and variety

One type of organ duplication can be called partial kidney duplication. His characteristic feature The special structure of the urinary organ is considered. Such kidneys have several bifurcated vessels and parenchyma. But the pelvis itself is not subject to such bifurcation.

Thus, the organ consists of two sections, independent of each other, and the renal sinus is divided by a bridge created from parenchyma. This non-standard division makes the kidney larger in size.

Doctors often do not classify this kidney disease as dangerous and do not make a special clinical conclusion about this. But when the pyelocaliceal system and ureters are doubled, a dangerous situation arises for the patient. Therefore, to clarify the entire clinical picture, excretory type urography may be prescribed.

Today, thanks to the achievements of science and new technical equipment, cases of the appearance of certain pathological abnormalities have become known, one of which is the abnormal structure of the organ. This pathology can have either partial or complete duplication of the urinary system.

Externally, the organ looks like two kidneys connecting to each other. But the uniqueness of the structure lies in the fact that each of them has its own independent blood supply. Quite often such pathologies develop on one side, but there are doublings on both sides.

The term “complete doubling of the kidney” is characterized by the peculiarities of its structure. Externally, the anomaly has a special difference - instead of one kidney, there are two. If pathological development occurred on the left side of the body, then such a person experiences a doubling of the organ’s heart rate. Despite the outwardly correct features of these organs, their structure has an abnormal structure.

With such doubling of the left kidney, one of its areas will have an inferior pelvis structure. The kidneys will have their own ureter for each pelvis. It can be located in a very unusual way.

Clinically, the disease does not manifest itself in any particular way.

A person can live his whole life with a double kidney and not even know about his unique body.

In the case when a complete doubling of the right or left kidney has formed, partial emptying of the abnormal organ occurs.

This can lead to various inflammatory processes that provoke serious disorders and development dangerous diseases. With such processes complications appear:

various changes caused by inflammation;
backflow of secretions may occur from the ureters;
urine accumulates in the pelvis and is retained for a long time.

For example, when the FLS doubles on the left or right, the patient may experience a sensation of pain in the lower back with a characteristic manifestation in the side where the abnormal development exists. In addition to the characteristic aching pain, other symptoms may predominate: fever, unexplained weakness, and swelling.

The patient may also experience frequent colic in the kidney area, a sharp rise in blood pressure, and problems with urination.

Doctors do not treat doubling of heart rate because they do not consider it a disease. But when inflammatory processes with complications occur, standard therapy is used, selecting the necessary antibiotics with an extended spectrum of action.

With this anomaly, kidney stones may appear, which cause colic varying degrees. Therefore, doctors can prescribe analgesics, herbal remedies and painkillers. If medication treatment does not work or severe stages of hydronephrosis appear, surgical intervention is possible.

Kidney doubling is the most common option congenital anomalies urinary system. This pathology in itself does not pose a danger to the patient. But its presence in a person predisposes to the development of other, more serious diseases.

What is kidney doubling?? In modern medicine, this concept is understood as congenital pathology kidney development, which is a complete or partial duplication of the renal system. In this case, the organ itself looks like two kidneys connected together, each of which has its own blood supply. More often, such changes appear only on one side, but cases of bilateral doubling are also common.

Causes

The cause of kidney doubling may be exposure to harmful factors on a woman during pregnancy or altered, defective genes of both parents. During the formation of the urinary organs, exposure to harmful agents is possible, which can lead to developmental abnormalities:

ionizing radiation;
insufficient intake of vitamins and minerals;
taking certain medications;
smoking and drinking alcohol.

Incomplete doubling

This is the most common developmental disorder of the urinary system. Incomplete duplication of the right kidney occurs as often as the left one. In this case, the organ is increased in size, and it is clearly possible to distinguish the upper and lower sections, each of which has its own renal artery. With incomplete doubling of the kidney, the pyelocaliceal system (PSS) does not bifurcate, but functions alone.

Full doubling

Complete doubling is characterized by the formation of two buds instead of one. Thus, when the organ on the left is doubled, the patient has a doubled FLS of the left kidney. However, one of the parts has an underdeveloped pelvis. Each pelvis gives off a separate ureter, which can empty into the bladder at different levels.

Clinical manifestations

The manifestations of this disease do not have any characteristic features. Incomplete duplication of the left or right kidney often does not produce any symptoms, and the patient lives his entire life without knowing about this anomaly.
With complete doubling, the clinic is associated with insufficient emptying of the pelvis of the “underdeveloped” organ.

Complications with their inherent symptoms will be the following:

inflammatory changes;
reverse flow of urine from the ureters;
hydronephrosis – retention and accumulation of urine in the pelvis.

For example, with complete doubling of the left kidney, the patient may feel pain in the lower back mainly on the left; Pasternatsky’s symptom will also be positive on the same side. In addition to pain there are general symptoms(weakness, swelling, fever). A person may suffer from frequent renal colic, symptomatic increased blood pressure, and painful urination.

Diagnostics

The diagnosis is most often made by chance during a routine examination.

In addition to ultrasound, they are used for diagnostic purposes. computed tomography, magnetic resonance urography and radiography. On an x-ray photo of a kidney duplication, it is not possible to see whether it is complete or partial division. Although in some cases, during an ultrasound examination, a specialist can recognize two independent CLS, which will lead to the idea of a complete bifurcation. But to clarify the correct diagnosis, patients undergo cystoscopy or ascending urography.

Thanks to a cystoscopic examination, the doctor can see the orifice of the ureters; in the case of complete doubling of the renal system, the number of orifices will be more than two. For example, with complete doubling of the right kidney, two ureters will enter the bladder on the right.

Ascending urography is based on the introduction of a coloring substance visible on X-ray photographs. The image will show the ureters, the place of their entry and an expanded CL in the case of incomplete doubling or two CL in the case of a complete doubling.

Treatment

Treatment for kidney duplication is carried out in case of any complications. If a person is not bothered by this anomaly urinary system, observation is recommended. It is advisable to conduct a clinical examination of urine and ultrasound of the renal system once a year.

For inflammatory complications, broad-spectrum antibiotics are selected.

With this pathology, stones can often appear, which will cause renal colic. Typically, in this case, antispasmodics, analgesics and herbal remedies (kidney tea, corn silk) are prescribed.

Surgical intervention is necessary for severe degrees of hydronephrosis or in the presence of diseases that are not amenable to drug treatment. Surgeons always try to preserve the organ. Its complete removal is carried out only if the kidney does not perform its function. If renal failure develops, hemodialysis and donor kidney transplantation are indicated.

Pregnancy with a bifurcated kidney

Pregnancy with a double kidney in a woman should be planned in advance. An expectant mother who knows about her pathology is required to undergo a full laboratory and clinical examination ( general tests blood and urine, urine examination according to Nichiporenko, determination of the biochemical composition of blood) and ultrasound of the kidneys.

Pregnancy is contraindicated in case of renal failure or if there are indications for surgical treatment.

Throughout the entire period of bearing a child, the woman is observed by a general practitioner and consulted several times by a nephrologist or urologist. If complications occur, the pregnant woman is hospitalized in the urology department.

Duplication of the kidneys in a child can be suspected already in the intrauterine state on an ultrasound scan after 25 weeks of pregnancy.

It must be remembered that a kidney with a developmental anomaly is more vulnerable. Therefore, a person should not be overcooled, eat salty foods in large quantities, is obliged to treat first of all all infections of the genitourinary system. People with this pathology must follow the rules for preventing complications and monitor their condition.
