A Case of Right Ureter-external Iliac Artery Fistula with Long Term Ureteral Stent

Abstract

Ureter-iliac artery fistula (UAF) is a relatively rare disease but occasionally causes fatal complications. We report a case of right UAF. A 78-year-old man was admitted with postrenal failure due to right ureteral stenosis and treated by inserting a double-J stent, which was replaced regularly. Four years after starting ureteral stenting, he needed hemodialysis treatment. As the right double-J stent was removed, he complicated with hematuria and anemia. Cystoscopy showed a high number of clots in the bladder. Although the fistula was not confirmed in contrast-enhanced computed tomography scan, a right UAF was highly suspected. The fistula was treated by direct closure of the external iliac artery fistula and right nephroureterectomy. The postoperative course is good, with no hemorrhagic episodes.
