What is a ureteral stricture?

A ureteral stricture is an obstruction in the ureter that interferes with the passage of urine from the kidney to the bladder. Most commonly, ureteral strictures are acquired as a result of injury, the passing of a stone, or inflammation, but may also be congenital. Flank pain, nausea, vomiting, and hematuria are symptoms associated with a ureteral stricture.

Evaluation

Evalution involves imaging studies identifying hydronephrosis (swelling of the kidney). Once hydronephrosis is identified imaging studies with contrast including a CT scan, an intravenous pyelogram (IVP) , or a retrograde pyelogram will be performed to further define the ureteral stricture. Additional testing may be necessary to determine how well the kidney(s) are working.

Treatment

Treatment depends on the location and length of the stricture and can range from a simple balloon dialation of the narrowed area or a complex surgical repair.
