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.

Objectives: This work aimed to prevent stoma stenosis and achieve tubeless cutaneous ureterostomy in elderly and high-risk patients with our modified cutaneous ureterostomy.
Methods: We retrospectively analyzed 40 and 49 patients (176 renal units) who underwent Toyoda (group 1) and modified cutaneous ureterostomy (group 2) between 2012 and 2021. The average follow-up period was 44 months.

Purpose: Cutaneous ureterostomy is a well-established surgical technique of incontinent urinary diversion treatment. However, stoma stenosis limits widespread utilization of this technique. We present our modification of constructing single-site tubeless cutaneous ureterostomy aiming to reduce stomal complications and improve catheter-free rate of those patients.

A 65-year-old man underwent radical cystectomy and cutaneous ureterostomy for bladder cancer. Because the patient had left complete duplex ureters,we modified the Toyoda method to construct the tubeless cutaneous ureterostomy with a unilateral stomal creation. The adhesive portion of both ureteral walls in duplex ureters was simultaneously cut approximately 5 mm from the distal end longitudinally,and the common sheath of the cut portion of the ureters was cut approximately 5 mm longitudinally in order to separate the two ureters.

Radical cystectomy, as the most common surgical treatment for patients with invasive bladder cancer (IBC) complicated by peritoneal metastasis, is usually accompanied by a urinary diversion procedure. In this study, we evaluated the improved tubeless cutaneous ureterostomy technique by comparing the resulting clinical effects with either a traditional ureterostomy and an ileal conduit urinary diversion. Clinical data from 85 patients who underwent 1 of the 3 procedures between April 2012 and April 2015 were analyzed retrospectively.

Introduction: We assess a novel technique of tubeless bilateral cutaneous ureterostomy, with a single umbilical stoma, for bladder cancer patients with short ureters after cystectomy. The benefit of cutaneous ureterostomy is equal to other incontinent urinary diversions, when the tubeless procedure is successfully achieved. This simple technique makes it easy to monitor the upper urinary tract (UUT) and is beneficial to patients with a high risk of UUT recurrence.
