Alternate Names : Ureteral obstruction – chronic, Obstructive uropathy – unilateral – chronic
Chronic unilateral obstructive uropathy is a condition in which there is long-term blockage of one of the tubes (ureters) that drains urine from the kidneys.
- Acute unilateral obstructive uropathy
- Acute bilateral obstructive uropathy
- Chronic bilateral obstructive uropathy
- Obstructive uropathy
Overview, Causes, & Risk Factors
Unilateral obstructive uropathy usually occurs when ureteral or kidney stones block the flow of urine. Urine backs up and causes kidney swelling (hydronephrosis).
Risk factors for unilateral obstructive uropathy include:
- Kidney stones
- Tumors in surrounding structures such as uterus, cervix, or lymph nodes
- Ureteral stones and tumors
Chronic unilateral obstructive uropathy occurs in approximately 5 out of every 1,000 people.
