Purpose: We performed an ileal W-neobladder for total bladder replacement and
evaluated this procedure in comparison with previously performed bladder substitution.
Materials and Methods: Total 21 patients underwent this procedure between September
1996 and December 1997. About 40cm long segment of the distal ileum was isolated and
arranged in W-shaped configuration. A spherical pouch, the neobladder, with the ureters
are implanted at each serous-lined intestinal trough was fashioned and was anastomosed
to the urethra.
Results: The mean operation time was 452 minutes. 4 patients were missed on
follow-up. Among the 17 remaining patients, there was no perioperative mortality or
serious immediate complication but mild ileus, atelectasis or wound disruption.
Reoperation was necessary in only 1 case due to wound dehescence. The late
complication was 1 case of ureterointestinal stricture which was managed with balloon
dilatation and 9/17 cases of nocturnal incontinence at 2 months after operation, which
was improved as times goes by. We could follow up more than 6 months in 8 patients
and they were all continent at night. Urinary reflux was not observed at 14th
postoperative day on cystography. All 17 patients had recognizable sensation of bladder
distension closely simulating those of normal bladders. The urodynamic study revealed a
capacity approximating that of a normal bladder and showed good compliance during
filling by maintaining low pressure.
Conclusions: According to our initial experience, the use of ileal W-neobladder in men
after radical cystectomy offers free of a stoma to urinary diversion, resulting in a highly
compliant, low pressure, and acceptable residual urine without serious complication.
