title: Simple technique for improving tubeless cutaneous ureterostomy.
abstract: BACKGROUND
  Cutaneous ureterostomy is the simplest and safest method of all permanent urinary diversions. However, the procedure does carry a risk of stomal stenosis. We describe a simple technique for improving tubeless cutaneous ureterostomy.
  
  
  METHODS
  Between June 1991 and June 2003, the Toyoda cutaneous ureterostomy was performed in 54 patients (102 renal units) with a minimum of 6 months of follow-up. Since 1998, we introduced a new technique, consisting of fixation between the anterior and posterior rectus sheath by four interrupted sutures to maintain the stability of the abdominal wall tunnel for the ureters. The ureteral patency rate was reviewed. Of the 79 renal units (77.5%) that achieved a tubeless condition, 70 (68.6%) had no hydronephrosis. The catheter-free rate improved from 60.5% (26 of 43 renal units) to 89.8% (53 of 59 renal units) with the introduction of the new surgical stabilization step for the abdominal wall tunnel.
  
  
  CONCLUSIONS
  This surgical modification is an effective and simple procedure that improves tubeless cutaneous ureterostomy performed with the Toyoda method.
