Life-threatening Arterioureteral Fistula Between Iliac Vessel and Ureteral Stump: A Case Report

Arterioureteral fistulas (AUFs) are a rare but life-threatening condition that cause massive hematuria. Radiation treatments, pelvic surgeries and chronic permanent ureteral stent use due to pelvic malignancies have been identified as the most important causes of AUFs. The number of cases in which arteriography and computed tomography angiography are insufficient and the pulsatile flow of the fistula can be observed only with ureterenoscopy is very rare in the literature. Here, we presented our 60-year-old patient with AUF, who has important risk factors such as pelvic surgery, radiotherapy and recurrent ureteral stent placement and whose pulsatile flow of the fistula was observed by ureteroscopy between the ureteral stump and iliac vessel
