Arterio-ureteral fistulas (AUFs), which are relatively rare but potentially life-threatening, require prompt diagnosis and treatment. We reported a case of AUFs following robot-assisted laparoscopic radical cystectomy (RARC) with extended pelvic lymph node dissection and ileal conduit urinary diversion for muscle-invasive bladder cancer, which resulted in massive hemorrhage. Urine leaked from the anastomosis between the ureter, and the end of the ileal conduit was infected, which resulted in an AUF between the pseudoaneurysm of the right common iliac artery and the ureter. The AUF was managed successfully by vascular intervention with an arterial stent graft.
动静脉瘘（AUFs）较为罕见，但可能危及生命，需要及时诊断和治疗。我们报告了一例机器人辅助腹腔镜根治性膀胱切除术（RARC）后发生的 AUF 病例，该手术行广泛盆腔淋巴结清扫和回肠导管尿流改道术治疗肌层浸润性膀胱癌，导致大量出血。尿液从输尿管和回肠导管末端的吻合口漏出，导致右髂总假性动脉瘤和输尿管之间发生 AUF。通过血管内支架移植术成功地进行了血管介入治疗来处理 AUF。
