Acute unilateral obstructive uropathy

Definition:

Acute unilateral obstructive uropathy is a sudden blockage in one or both of the tubes (ureters) that drain urine from the kidneys.

Alternative Names:

Obstructive uropathy - unilateral - acute; Ureteral obstruction

Causes, incidence, and 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 such as the uterus and cervix .

Acute unilateral obstructive uropathy occurs in 1 in 1,000 people.
