A 55-year-old man presented with a massive hemorrhage from the ileal conduit of the left ureter. He had previously undergone a total pelvic exenteration with ileal conduit construction of the ureters due to rectal carcinoma. A right ureteroarterial fistula developed, and he underwent an excision of the right common iliac artery with a femorofemoral bypass and a right cutaneous ureterostomy. Seven months later, a pseudoaneurysm developed at the aortic stump, followed by an aorto-ileal-conduit fistula. The patient was treated successfully with endovascular stent grafting and has since showed a good recovery no sign of graft infection or a recurrence of hematuria at the 10-month follow-up.
