A 72-year-old man underwent total cystectomy with single stoma cutaneous ureterostomy for the treatment of transitional cell carcinoma of the bladder. The patient came to the outpatient clinic every 2 weeks to exchange ureteral catheters. Six months after the operation, he was admitted to our hospital again due to edema of bilateral legs, fever, and loss of appetite. The patient had metastasis of intrapelvic and paraaortic lymph nodes associated with cachexia, and was given intravenous hyperalimentation and treatment to control pain. Suddenly, he complained of left flank pain. When the ureteral catheter was removed, massive bleeding occurred from the stomal orifice. A fistula between the artery and ureter was suspected. Six days later, the patient died due to acute renal failure. After his death, retrograde ureterography was performed to confirm the fistula. A fistula was found between the left common iliac artery and left ureter.
