Obstructive Uropathy: Causes, Symptoms and Treatment

It is a condition in which the flow of urine is obstructed, causing it to be stored and injuring one or both kidneys of our body.

This condition occurs when the urine does not drain through a ureter (the tube that carries urine from the kidneys to the bladder), accumulating in the kidney and causing inflammation ( hydronephrosis ).

Causes

  • Bladder stones
  • Kidney stones
  • Benign prostatic hyperplasia (enlarged prostate)
  • Urethral cancer
  • Colon cancer
  • Cervical cancer
  • Uterine cancer
  • Any cancer that spreads
  • Problems with the nerves that innervate the bladder

Obstructive uropathy may rarely occur during pregnancy. This is called idiopathic hydronephrosis of pregnancy.

symptom

  • Mild to severe pain in the middle part of the body (back pain) you feel on one or both sides
  • Fever
  • Vomiting or Nausea
  • Swelling or weight gain (edema)

You may also have problems urinating, such as:

  • I need to urinate very often
  • Decreased strength when urinating
  • Drip urine
  • It does not feel like the bladder is empty
  • Increases the need to urinate more often at night
  • Decrease in the amount of urine
  • Presence of blood in the urine

Signs and Exams

The diagnosis of obstructive uropathy is made in imaging studies. Common radiographic studies used to diagnose it include:

• Ultrasound of the ventral area (abdomen) or pelvis

• Computed tomography of the belly area (abdomen) or pelvis

• Nuclear Renal Scanner

Treatment

Drains placed in the ureter or a part of the kidney can provide short-term relief of symptoms.

Nephrostomy catheters, which drain urine from the kidneys through the back, can be used to prevent obstruction.

 

A Foley catheter, placed through the urethra to the bladder, may also be helpful.

The short-term relief of the obstruction can be achieved without surgery, the cause of the block must be removed and the urinary system repaired. Prolonged replacement of obstructive uropathy requires surgery.

Forecast

If a sudden obstruction is diagnosed and repaired quickly, kidney damage is less likely. Often, damage to the kidneys goes away.

It can cause long-term damage to the kidneys if you have had obstructive uropathy for a long time.

If only one kidney is damaged, chronic kidney problems are less likely.

When both kidneys become damaged and stop working even after the obstruction is corrected, you may need dialysis or a kidney transplant.

If the obstruction or blockage of the bladder was the cause, it could cause long-term damage to the bladder. This can result in problems emptying the bladder or leaking urine.
