How to understand that extended the renal pelvis during pregnancy and how to treat

hydronephrosis is called a pathological condition when forming the progressive increase in the renal pelvis.This happens due to mechanical disturbances and discharge of urine is accompanied by an increase of pressure in cups and pelvis of the kidneys.

Stagnation of urine pelvis provokes the expansion and thinning of the walls, so it can start the development of atrophy in the kidney parenchyma.Expanded renal pelvis during pregnancy is usually only on one side.

reasons pathology

The main reasons for the development of hydronephrosis during pregnancy include the following:

  • abnormalities in the bladder or urethra, because the formation of barriers in these departments provokes hydronephrosis.
  • Changes in the ureters - their twisting, squeezing, creases and other deformations.Changes in the ureter provoke the development of hydronephrosis on the affected side, which often manifests itself during pregnancy.
  • Inflammation in the pelvic or retroperitoneal fat.
  • formation of stones in the renal pelvis or
    ureter.They interfere with the proper discharge of urine, hydronephrosis and is considered an early sign of kidney stones.
  • narrowing of the lumen in the ureter through the connective tissue.
  • disorders of the urinary channel operation - hypotension ureteral or renal pelvis, etc.Such processes cause a slowing of peristalsis of the ureters, causing hydronephrosis in pregnant women.

Regardless of the causes of the expansion of the renal pelvis of the disease during pregnancy is complemented by a gradual violation of a discharge of urine, urine stagnation and as a consequence an increase in the size of the renal pelvis.At the same time there is an increase in the kidney pressure, impaired blood flow, manifested popochki filtering and atrophy of the parenchyma tissue.

Over time, the walls of the renal pelvis are stretched strongly influenced by the hydrostatic pressure, and there is thinning.This process contributes to the violation of the excretory function of the body.

Symptoms Pathology

Chronic disease can occur without clinical manifestations.The increase in the renal pelvis during pregnancy can cause nausea, vomiting, nagging pain in his side.With the development of urinary flow disturbances in the lower pain are manifested due to the stretching of the walls in the bladder.

During pregnancy, women often complain of a dull pain radiating to the groin area or in the thigh.Rarely appear strong pain, like an attack of renal colic on.Such pain may occur against the background of weak nagging pain radiating to the lumbar region.

If a pregnant woman severely hurt the kidneys, then the error such pain can be confused with the threat of abortion or premature delivery.Often the pain is complemented by urinary retention, and after childbirth pain gradually subside.

Diagnostic Pathology

If increased renal pelvis during pregnancy, the diagnostic process is to examine complaints and collecting data history.A presumptive diagnosis is confirmed by an ultrasound of the abdominal organs.

In the early stages detected not strong expansion of the renal pelvis.Later in the cup are utilized, and there is an increase across pyelocaliceal system in the kidney.In the terminal stage of kidney disease is the formation of a large cyst-like.

To diagnose the disease in pregnant women is organized ureteral catheterization.Thus the catheter is introduced into the pelvis, emptying it, and then a contrast agent is injected.


With the development of the pathology of hydronephrosis management of pregnancy will depend on how long ago there was a pathology, during or before pregnancy, whether additional infection are present, and whether the normal operation of kidney retained.

If hydronephrosis first appeared during pregnancy, it can be stored except in cases of acute illness.The infection can be treated.Pain can be relieved with the knee-elbow position of the body.Such signs shall be of diagnostic value.

If hydronephrosis began to develop even before pregnancy, the doctor may raise the question of its artificial interruption.The decision should be taken in the hospital and only after a full examination of opportunities kidneys work, the presence of infections, and provided accounting reasons, provoke the development of hydronephrosis.
