[A Case of Ureteroarterial Fistula Successfully Treated with Endovascular Stent Graft].

We report a case of right uretero-external iliac artery fistula. A 46-year-old woman diagnosed with left ovarian cancer with peritoneal dissemination underwent simple hysterectomy, bilateral adnexal removal, partial omentectomy and appendectomy. Sixteen months after the operation, a computed tomography scan showed right hydronephrosis due to the development of tumor within the pelvis. A ureteral stent was placed into the right ureter in order to preserve renal function. The ureteral stent was replaced at regular intervals. Five months after the ureteral stent placement, the patient was hospitalized urgently with gross hematuria. She was diagnosed with right uretero-external iliac artery fistula based on the angiographic examination that was conducted to detect the source of hemorrhage. She was treated successfully with endovascular stent grafting in the right external iliac artery. She has since shown no episode of hematuria.
