Ureteral stricture is most commonly caused by congenital or acquired ureteropelvic junction obstruction or narrowing. Causes include previous treatment of urologic condition, pelvic radiation therapy, urinary diversion surgery, kidney stone passage, renal transplantation, trauma, congenital anomalies, and certain cancers.
Early detection may help prevent severe renal complications. Treatment varies depending on the cause and type of ureteral stricture and should be individualized to the patient. For strictures that develop acutely after trauma, surgery may be suggested. For strictures that develop chronically, endoscopy may be suggested.
