In some patients with intractable symptoms from incurable pelvic cancer, for example, urgency, severe hematuria, fistula formation and hydronephrosis, palliative urinary diversion with intestinal segments may not be available. Percutaneous nephrostomy or indwelling of double-J ureteral stents were usually performed. However, they suffered catheter trouble and their quality of life considerably worsened. Therefore, we developed a new technique of bilateral extraperitoneal tubeless cutaneous ureterostomy with single umbilical stoma. It resulted in symptom relief in 3 patients. The advantage of this method was as follows. The dissection was entirely extraperitoneal. The operative time was short and the procedure could be performed easily. The left ureter need not be led behind the mesosigmoid. Finally, ostomy care was easy with only one bag.
