  • How does

hydronephrosis hydronephrosis - a disorder characterized by the expansion of the renal pelvis and a violation of the outflow of urine.This can occur as a result of normal processes, or due to various underlying diseases.Normally, the kidneys filter blood and outputting various wastes in the urine.Then the urine flows into the renal calyx, and then - in the renal pelvis.After that urine enters the ureter, the tube that connects the kidney to the bladder.From the bladder through the urethra, the urine leaves the body.

Although the most common cause of obstruction hydronephrosis are different, this violation is linked to some birth defects;sometimes kidney hydronephrosis is a physiological response to pregnancy.

hydronephrosis may be unilateral, when it affects only one kidney or bilateral.

complication hydronephrosis is a decline in renal function.Pressurizing excess fluid in the kidneys reduces the amount of blood that is filtered in the body, and can cause structural damage to the kidney cells.This decrease in the function is reversible, if the time to cure the underlying disease, but if hydronephrosis lasts several weeks, the damage may be permanent.


hydronephrosis can be caused by many reasons, which are classified depending on whether they are internal (located in the urine), or external (located outside the system).

Internal causes kidney hydronephrosis:

  • kidney stones.This is probably the most common cause of unilateral hydronephrosis;stones often cause obstruction of the urethra.
  • Blood clots in the ureter.
  • formation of scar tissue in the ureter.
  • Bladder Cancer.
  • bladder stones Urinary bladder - structure and function Urinary bladder - structure and function .
  • cystocele.
  • bladder neck contracture.
  • Impaired ability to empty the bladder, for whatever reason, could lead to bilateral hydronephrosis.
  • various violations of the structure of the urethra.

External causes of hydronephrosis:

  • benign or malignant tumors that compress the ureter and prevent urine output.
  • retroperitoneal fibrosis.
  • cervical cancer.
  • Prostate Cancer.
  • pregnancy.
  • Uterine prolapse.
  • scarring after radiotherapy.
  • hypertrophy of the prostate.
  • Prostate Cancer.

Symptoms Symptoms of kidney hydronephrosis depend on the underlying cause.

In acute hydronephrosis may appear symptoms such as severe pain in the back Back Pain: Do not start the Back pain: Do not start the process , smack in the groin, as well as nausea, vomiting, and sweating.In addition, a person may experience renal colic - this pain is one of the most severe pain that a person can experience.

Chronic hydronephrosis develops gradually and has no specific symptoms.Nonspecific symptoms may be weakness, lethargy, nausea Nausea - there may be problems with the nervous system Nausea - there may be problems with the nervous system and vomiting.If due to the decline of renal function occurs imbalance of electrolytes can be observed cardiac arrhythmias and muscle spasms.

patients with symptoms of acute kidney hydronephrosis need urgent medical attention.In addition, people who have previously been diagnosed with kidney hydronephrosis need to see a doctor for any signs of infection - such as fever, chills or a fever.Immediate treatment is also necessary in patients who have previously had one kidney removed.


primary goal of treatment of hydronephrosis kidney - the restoration of the normal flow of urine from the kidneys and reducing and inflammation.

First of all, doctors are taking measures to reduce pain and prevent infection of the urinary tract.If this is not done in time, you may need surgery.

Duration of treatment usually depends on the underlying disease and its complications.For example, if the patient has kidney stones, which are not completely disrupt the flow of urine, he can stay under medical supervision a week or two, until the stones do not pass the ureter.At this time, as a rule, the patient only takes painkillers regularly.When complete ureteral obstruction, infections, and in patients with hydronephrosis one kidney requires surgery.

If hydronephrosis is caused by stagnation of urine, primarily used bladder catheterization.

Shock-wave lithotripsy - a common means of treatment for kidney stones, which is also used in the treatment of patients with hydronephrosis of the kidney.During the procedure, kidney stones Kidney stones: identify and treat Kidney stones: identify and treat ground using impact from the outside, and then they will go out of the ureter.
