Abstract:
Ureteral artery fistula (UAF) is a rare complication after long-term indwelling of ureteral stent. In this study, two cases were presented. Both of them underwent pelvic tumor surgery and radiotherapy, and had a history of cutaneous terminal ureterostomy and long-term indwelling of ureteral stents. The first case, a 52-year-old female, was admitted to hospital because of intermittent bleeding from ureteral dermostomy for 1 week on April 2, 2020. CT examination revealed hematocele in the left upper urinary tract, and left nephrectomy was performed.However, bleeding still presented and the distal ureteral resection was performed at the same time, and partial ureteral was ligated. Postoperative diagnostic was ureteral artery fistula. After 8 months of follow-up, no recurrent bleeding presented. Another case, a 82-year-old male, was admitted to hospital because of bleeding at the ureteral dermostomy for an hour on June 15, 2020. Contrast enhanced CT examination revealed intersecting of the left ureter and common iliac artery, and interventional surgery was performed, by which UAF was diagnosed. Embolization of left internal iliac artery and stent implantation of common iliac artery and external iliac artery were performed intraoperatively. The bleeding stopped immediately after the operation, and there was no further bleeding during follow-up of 6 months.
