Hydronephrosis of kidneys in children: symptoms and treatment

Hydronephrosis of the kidneys in children, as a rule, is of an innate nature. What is hydronephrosis? By this terrible word I call pathology, which is characterized by an increase in renal calyxes, pelvis due to the large amount of urine accumulated in them, while the outflow of urine is disturbed.

Causes of



The cause of congenital disease is the anatomical features of the body. There are two types of reasons - internal and external. The internal cause of the appearance of hydronephrosis is the underdevelopment of the lumen of the ureter, which provokes its narrowing. As for external causes, they directly depend on the vessel that causes compression of the ureter, as well as from the abnormal retraction of the ureter from the pelvis.

Symptoms of kidney hydronephrosis in children



Congenital hydronephrosis of kidneys in children develops accompanied by pyeloectasia, that is, an expansion of the pelvis. The disease can easily be diagnosed by ultrasound, which allows to identify it during the period of intrauterine development. But there are cases when hydronephrosis begins to manifest after the birth. Then the following symptoms are present:

  • The presence of blood in the urine, that is, hematuria

  • Formation in the abdominal cavity of unknown etiology

  • Systematic infections of the genitourinary system

  • Pain in the abdomen


  • Treatment of kidney hydronephrosis in children



    It is possible that the symptoms of hydronephrosis disappear, but this does not happen as often as we would like. For the baby it is necessary to constantly observe, visiting the urologist doctor at least three times a year to three years of age - an obligatory rule. Then one visit per year is enough.

    Treatment of kidney hydronephrosis in children of moderate severity depends on the dynamics of development. Often with the gradual expansion of the renal pelvis, doctors recommend surgical treatment of the disease. In this case, the ultrasound is carried out for three months.

    When there is a pronounced hydronephrosis in conjunction with a violation of urinary excretion, surgical intervention is inevitable.

    Carrying out the operation



    The operation that is performed in the treatment of hydronephrosis is called pyeloplasty. This surgical intervention in the children's organism includes excision of the defective site of the ureter, the formation of a new ureteral connection with the pelvis.

    Pyeloplasty by Hynes is the most common operation. The narrowest section of the ureter is located very close to the pelvis. After excision of the ureter, the renal area is incised longitudinally, its edge is sewn with the edge of the incision on the renal pelvis. To ensure a uniform lumen, as well as to avoid deformation of the anastomosis, the clinging doctor conducts a tube in the junction of the ureter and pelvis. In this case, the second end of the tube is discharged into the bladder or through the kidney tissue.
