We report a 5-year experience with 52 patients who underwent radical cystoprostatectomy for bladder cancer and orthotopic bladder substitution using a novel personal modification of the S pouch.
From September 1995 to December 1999, 52 men 36 to 72 years old (mean age 63) underwent bladder substitution with an S pouch. They were followed until September 2000. The pouch was constructed with a 36 cm. segment of ileum with the whole length used for the reservoir. The ureters were directly anastomosed with one above the other in the mid segment of the pouch without any antireflux procedure. Complications were documented and classified as early or up to 3 months postoperatively and late, and further subdivided by the relationship to neobladder construction. Continence and voiding pattern were evaluated by personal interview and neobladder function was urodynamically assessed. Mean followup in our patients was 30 months.
The most common of the 5 early and 9 late neobladder related complications were persistent urine leakage and reflux, respectively. There was no reflux greater than grade III in the 4 patients with reflux (5 refluxing ureters) and no functional disorders. We observed 12 early and 5 late complications unrelated to the neobladder. Open reoperation was required in 5 cases. Good or satisfactory daytime and nighttime continence was reported by 95% and 88% of our patients, respectively. By year 1 postoperatively 91% of our patients voided at an interval of 3 to 5 hours during the day. Mean maximum neobladder capacity was 672 ml. and mean post-void residual was 30 ml. by year 3 postoperatively. Two patients required self-catheterization once daily and mild hyperchloremia without acidosis developed in 2.
The advantages of our modified S pouch are technical simplicity, substantially shorter operative time and decreased bowel length required. It is associated with an acceptable complication rate and functional parameters with subsequent patient satisfaction and good quality of life.
