Alternative names:

Uropathy - obstructive

Definition:

A disorder involving blockage of the flow of urine, resulting in the backup of urine and injury to the kidney(s).

Causes and Risks

Obstructive uropathy occurs when the kidney produces urine in the normal manner but the urine cannot drain normally because of an obstruction. Urine backs-up and causes damage to the kidney(s).

Obstructive uropathy is further differentiated by whether it affects one or both kidneys, and whether it developed suddenly (acute) or slowly (chronic). See the following documents:

• Chronic unilateral obstructive uropathy
• Chronic bilateral obstructive uropathy
• Acute unilateral obstructive uropathy
• Acute bilateral obstructive uropathy

Common causes of obstructive uropathy include:

• Urinary tract stones
• Ureteral stones
• Bladder stones
• Urinary tract tumors
• Retroperitoneal fibrosis
• Benign prostatic hypertrophy
• Adjacent organ tumors
• Colon cancer
• Cervical cancer
• Uterine cancer
• Metastatic cancer
