title: Arterial-ureteral fistula: case study with review of published reports.
abstract: Arterial-ureteral fistula, a rare cause of gross hematuria, may be associated with life-threatening hemorrhage if not rapidly diagnosed and treated. Recently, a patient at the Hunter H. McGuire Veterans Administration Medical Center developed an arterial-ureteral fistula at the site of the confluence of the external iliac artery and a superior mesenteric artery bypass graft. Review of the world's literature revealed 31 additional reported cases of arterial-ureteral fistulas. This current case is only the second one reported in which the diagnosis was made with arteriography. Several common features of arterial-ureteral fistulas were present in this case: a history of ureteral obstruction and urinary tract infections, upper urinary tract disease, and previous vascular surgery. The condition is usually associated with either prior upper urinary tract instrumentation or vascular surgery, and an antecedent period of intermittent hematuria, followed by life-threatening hematuria, is common. A high index of suspicion and early surgical intervention are required for successful management. The major surgical challenges are to establish unobstructed urinary drainage and restore vascular continuity. Exclusion of prosthetic material from potentially infected areas is mandatory.
