title: [Uretero-external iliac artery fistula: a case report].
abstract: We report a case of uretero-external iliac artery fistula. A 60-year-old female was referred to our hospital complaining of intermittent gross macrohematuria. She had undergone radical hysterectomy, radiation therapy and chemotherapy for advanced cervical cancer 2 years ago. The patient had a 7 Fr ureteral double-J stent for left hydronephrosis. Retrograde urography showed a filling defect (8 mm in diameter) of the left ureter. A contrast-enhanced computed tomographic scan showed left hydronephrosis and hydroureter but no evidence of fistula formation or extravasation. A pelvic arteriography revealed a pseudoaneurysm of the left external iliac artery at the crosspoint between the left ureter and the iliac artery. Surgical repair of the left uretero-external arterial fistula was successfully performed as well as left nephroureterectomy. The possibility of fistula formation between ureter and artery should be kept in mind in patients with long-term indwelling ureteral stents and history of radiation therapy.
