Doubling kidney in a child: a characteristic of pathology, its variety

At present, doubling the kidney in a child is the most common form of pathological development of the urogenital system. This lesion is not considered an independent disease and basically it is not characterized by clinical symptoms, but there is a tendency of the body to form inflammatory nephropathies in the kidneys.

The described lesion is often detected in children, especially in girls. Doubling a kidney in a newborn can affect one side or both of the kidneys at the same time, or it may be complete or incomplete. With the development of a complete doubling, the organ is divided into two parts with its own ureters opening up to the individual mouths in the bladder.

With the development of incomplete doubling, there is usually a fusion of ureters at a certain level. In this case, often the defeat is accompanied by protrusion of the wall in the ureter into the bladder.

The signs of kidney doubling are:

1. Kidney stones.
2. Pyelonephritis.
3. An omission of the organ.
4. Hydronephrosis.

The manifestation of pyelonephritis in the development of kidney doubling in a child contributes to improper withdrawal of urine, because this pathology is usually supplemented by protrusion of the ureter wall in the likeness of a hernia. The same causes affect the formation of kidney stones.

Anatomical picture of the doubled kidney

In its anatomical structure, the double kidney looks as if the two buds have merged and have an independent blood flow - that is, there are two arteries in them. In this case, the lower part of the organ becomes more significant. Renal tissue and the blood flow system is doubled in any case, but the ureter and renal pelvis are not always removed, which means that an incomplete form of pathology develops.

This is important! Also an additional ureter can be combined with the main one in any of its often before entering the bladder. At the junction of the two ureters, a constriction often appears, provoking a violation of the correct retraction of urine, reversing its casting into the pelvis and hydronephrosis.

Reasons for doubling in the body

Doubling in the kidney, as well as other intrauterine pathologies, mainly correlate with the effect on the body of teratogenic factors, with the transfer of the pathological gene to the child from his parents.

The most popular and frequently occurring in modern medicine factors of pathological effects on the human body include ionizing radiation of the mother's body during pregnancy in the first months of gestation, the use of hormonal drugs, certain chemical compounds and the lack of minerals and vitamins in the body.

These factors affect the gene structure and disrupt the construction of chromosomes, in addition, they negatively affect the cell division, thereby provoking a doubling of the left kidney in the child or the right kidney.

Clinical manifestations of the pathology and its diagnosis

The incomplete duplication, in which there is no duplication of the renal pelvis, often has no manifestations and is revealed quite by chance, when the target CT or X-ray of the kidney is being performed.

Complete duplication with the development of the second ureter and its place in the bladder can be diagnosed by cystoscopy after the discovery of the third mouth. However, most patients with incomplete duplication of the kidney, on the left or on the right side, live a full life and do not even suspect that this disease develops in their organism.

With full duplication, clinical signs are based on the symptoms of inflammation that form in the kidneys, on the development of urine back-casting and hydronephrosis transformation. Thus, a person begins to complain of severe pain in the lower back, an increase in body temperature and weakness. In addition, there is pain during urination, a positive symptom of kidney effleurage. With the widening of the lumen of the renal pelvis, colic develops, swelling, blood appears in the urine, blood pressure rises.

This is important! The listed symptoms are considered specific and manifest simultaneously whether individually - it depends on the form of the course of the disease.

The diagnosis of doubling of the kidney is made after the implementation of an X-ray examination, MRI, computed tomography, ultrasound or cystoscopy.

The upper part of the affected kidney sometimes changes so much due to the development of pyelonephritis in it or the obstructive process, so that the parenchyma is almost completely thinned, wrinkled, and the work of the segment is atrophied.

The ultrasound examination establishes the formation of a cystic neoplasm in the upper part of the pole, and the diagnosis is made by excretory urography on the basis of the following indirect signs: absence of an upper cup in the lower pelvis, displacement of the pelvis downward, deformation, asymmetry of the calyxes and presence between the pelvic edges and the upper pole of the kidneymute zone, an increase in the kidney in size.

The need for the medical process

Direct operative treatment of kidney doubling in a child is performed only under the condition of extreme necessity and serious complications. Often the therapy remains conservative and involves the prevention and stopping of the development of possible complications.

This is important! Thus, in the case of pyelonephritis, traditional therapy is performed by taking antibacterial medications. With the development of acute nephrolithiasis or otherwise colic, the patient is provided with usual care: immersion in a bath with warm water, the introduction of antispasmodics. It is recommended strict adherence to a diet prescribed by a specialist, which allows you to destroy already formed kidney stones.

Surgical operation is performed only with pronounced hydronephrosis transformation or other conditions that make it impossible to conduct conservative treatment. Doctors in this case prefer organ-saving operations, and nephrectomy, that is, complete removal of the organ, is performed when incomplete doubling of the right kidney or other form of the described abnormality provokes a complete loss of the kidney's ability to work normally. But this happens only when the process of the disease is started and there are no necessary measures of treatment and prevention.
