* Obstructive uropathy
Overview, Causes, & Risk Factors
Unilateral obstructive uropathy is most often caused by a kidney stone, although injury or other conditions could cause the disorder.
When urine flow is blocked, it backs up into the kidney. This leads to kidney swelling, also called hydronephrosis.
You have a greater risk for unilateral obstructive uropathy if you have ureteral stones and tumors, kidney stones, and tumors in nearby body structures such as the uterus and cervix.
Acute unilateral obstructive uropathy occurs in 1 in 1,000 people.
