Does detubularization improve continence in bladder replacement?
Camey in the seventies promoted bladder replacement. In 1987, the French Association of Urology gave us the opportunity to review 729 Tubularized Ileocystoplasty (Camey operation) [1]. The day time continence was excellent or acceptable (mild stress incontinence) on 91% of the patients, the night time continence was excellent (no pads, no leakage) or acceptable (one pad or less than 3 wakes at night) for 44% of the patients (56% had to use a device). Since 1985, the detubularization attempted to improve the continence rate. Today, the review of the literature shows that day time continence has not changed and the night time continence improved less than 20% arising from 44% to 60%. Bladder replacement after prostatocystectomy has been proved to be superior to continent urinary diversion in patients whose urethral and external sphincter can be preserved. Day time continence is excellent in tubularized and detubularized bowel reservoirs. Night time continence, in 30 to 50% of patients, remains an unresolved problem also in detubularized low pressure reservoirs, even if they are of great capacity. The literature is therefore too optimistic when describing night time continence in 85% of the patients. These results are stated in spite of the absence of sensitivity in the neobladder, the loss of reflexic increase in sphincteric activity during bladder filling, and the low sphincteric tonus during sleeping. These optimistic results are due to lack of unanimous criteria for evaluating continence after bladder replacement and not taking into consideration as continence failure the abundant although not frequent nighttime incontinence. In order to improve continence, muscle reeducation and artificial sphincter implantation are the most adequate solutions.(ABSTRACT TRUNCATED AT 250 WORDS)
