RESUMEN
Common iliac artery ureteral fistula is a rare but potentially life-threatening disease which is difficult to diagnose clinically. This paper reports a case of common iliac artery ureteral fistula. The patient was admitted to our hospital due to ureterostomy bleeding for one day. He underwent radical cystectomy and bilateral ureterostomy for bladder cancer 4 years ago, and also underwent radiotherapy and bilateral ureteral stents indwelling after the operation. Angiography revealed a left common iliac artery pseudoaneurysm, and a left common iliac artery ureteral fistula was considered. The left common iliac artery stent-graft was implanted. The patient recovered well after the operation, and there was no obvious hematuria during follow-up period of 6 months.
