Pyelectasis kidney, the child, adult and in pregnancy — causes, symptoms and treatment

The medical term «pyelectasis» translates from Greek as pyelos suck, ectasia – extension. Disease indicates that the flow of urine from the renal pelvis is broken due to the wrong anatomical structure or past infection. Classification code ICD-10 has class Q 62.

Pyelectasis kidney — what it is

Kidneys – paired organ that is located behind the peritoneum and are protected from damage by the capsule. They constitute a system of cups that are connected to the pelvis. Pyelectasis is an extension of the pelvis of the kidney, which prevents the full outflow of urine. There are other names of this process and its variants:

  1. Dilatation of CHLS (pan-pelvis-plating system);
  2. Pyeloureterostomy;
  3. Pyeloureterostomy;
  4. Paleolibertarianism;
  5. Silicomanganese;
  6. Ureteropyeloscopy;
  7. Ureterocystoplasty;
  8. Ureteropyeloscopy.

Pathological change is not a separate disease, but only accompanied by other inflammatory processes. There are different reasons why illness occurs:

  • Oncology;
  • congenital malformations;
  • kidney stones;
  • urine reflux into the renal pelvis or ureteral reflux.

Of etiology doctors distinguish four types of disease:

  1. Dynamic congenital arises from the fact that the ureter is narrowed, the process of urination becomes difficult. Is the result of a congenital phimosis.
  2. Dynamic purchased when squeezing parts of the urethra occurs after prostate cancers, kinked ureter and pyelonephritis.
  3. Organic acquired – narrowing and bending of the ureter occurs after external or internal injury, inflammation, exposure to copious amounts of liquid, hormonal disorders, prolapse of the kidney.
  4. Organic birth – defect during intrauterine development of the urinary function, which arose as a result of renal inflammation.

Pyelectasis of the right kidney

The monitoring of doctors-nephrologists, patients often expanded renal pelvis on the right. This is due to the structure of the body. Pyelectasis of the right kidney – unilateral expansion of the renal pelvis. Predominantly affects men and newborn babies. In severe form the inflammation extends to the ureters and cups. Complication of the disease is paleoclimate right kidney – stone formation in the cavity of the pelvis.

Pyelectasis of the left kidney

Pyelectasis of the left kidney, and right, goes unnoticed and asymptomatic, although left disease occurs much less frequently. Clear signs of left-sided enlargement in adults begin to appear only at the last stage, so you need to be screened regularly in order to prevent disease and to choose the right treatment.

Bilateral pyelectasis

Unlike the previous forms, bilateral pyelectasis develops very rarely. In this case, the expansion of the renal pelvis in both bodies. This condition is extremely dangerous, because the healthy kidney can not cope with the withdrawal of urine. Without medical intervention, there is atrophy of renal tissue, sclerosis of the urinary system.

Pyelectasis — symptoms

There are three degrees of disease according to ICD code:

I. reasonable;



At the initial stage the symptoms of the pyeloectasia in an adult may not show. The patient feels pain in the kidneys, the process of urination also takes place without problems. Another thing, when the expansion of the cavities of the kidneys took bilateral. Stagnation of urine, followed by a decrease in the size of the kidney (atrophy), renal failure.

Later there are other signs:

  • pain in the upper part of the waist;
  • rare urination;
  • pain in the abdomen;
  • the increase in temperature.

If time does not confirm a diagnosis, the disease passes in 2 and 3 stage, develop abnormal processes:

  1. Megaureter – a thickening of the ureter because of the strong pressure on the bladder.
  2. Ectopia – the confluence of the ureter into the vagina in women and urethra in men.
  3. Urethrocele – protrusion of the ureter at the junction with the bladder.
  4. Bubble vesicoureteral reflux — urine leaking back into the renal cavity.

Pyelectasis in the fetus

Modern methods give a chance to diagnose the disease in a child in early pregnancy. Renal pyelectasis of the fetus is visible on ultrasound and obstetric 16-20 weeks. Discovered the relationship between education anomalies with the floor of the fruit – girls are 3 times less often than boys. The main cause of fetal disease development – neurogenic dysfunction of kidney disease in the mother during pregnancy, genetic predisposition.

Pyelectasis kidney in a child

The disease is diagnosed with prematurity, infants with insufficient weight. Pyelectasis in newborns is the result:

  • perinatal lesions of the nervous system;
  • fragmented formation organs;
  • improper development of the valve ureteropelvic junction.

Hypertonicity of the muscles peculiar to this disease, interferes with the normal excretion of urine, so it is stagnation in the kidneys. Often minor ectasia buds in infants first and second degree does not require intervention, with age, it gradually goes away. However, if the disease is associated with serious kidney failure or inflammation, be sure to start the treatment infants.

Renal pyelectasis in pregnancy

The increase in size of the uterus during pregnancy, leading to compression of ureter and urinary retention in the kidneys. Pyeloectasia in pregnancy is not uncommon and disappears after childbirth. However, there is a risk of other serious diseases of the kidneys in pregnant women: eclampsia and pre-eclampsia (edema), stones, pyelonephritis, hydronephrosis, and development of dilated pelvis in the unborn child.

Pyelectasis kidney – treatment

The choice of methods of treatment, the doctor sends the patient for an examination, which includes, according to the code of the ICD, ultrasound and comprehensive blood and urine tests. Upon confirmation of the diagnosis in some cases is urography – x-ray study using contrast agent. Subsequent treatment of pyeloectasia will depend on the form of the disease. In most cases medication is not needed, but recommended to do ultrasound in 3-4 months.

If the disease is complicated with pyelonephritis, renal prescribed or herbal drugs the plant components that have anti-inflammatory effect. Well help methods exercise therapy and physiotherapy. A surgical operation is performed, if the urine flow is severely compromised. Modern endoscopic methods allow to eliminate the defect through a small incision.
