Acute unilateral obstructive uropathy

Alternative Names

Obstructive uropathy – unilateral – acute; Ureteral obstruction

Definition of Acute unilateral obstructive uropathy

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

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.

Signs and tests

The health care provider will perform a physical exam. Pressing with the fingers on (palpation of) the belly area may reveal a swollen or tender kidney. Blood pressure may be high.

Treatment

The goal of treatment is to relieve or reduce the blockage.

Expectations (prognosis)

The outcome varies. The disorder may result in permanent damage to the kidney. However, kidney failure usually does not result because the second kidney continues to function.
