[Continent replacement enterocystoplasty using a low-pressure detubularized ileal pouch after radical prostatocystectomy].
Tubular ileal-ileo-caecal or colonic replacement enterocystoplasties induce nocturnal incontinence in more than 70% of cases, partly due to the presence of peristaltic waves responsible for pressures greater than 40 cm of water for low filling volumes. The use of debutularised intestinal grafts considerably attenuates these pressure waves, ensuring excellent diurnal continence and a dramatic reduction in nocturnal incontinence together with protection of the upper urinary tract. The detubularised ileal bladder combines the reliability of all low pressure reservoirs with a simple technique: a 30 cm ileal segment is isolated then opened 2 cm from its anti-mesenteric border. The two limbs of the loop are sutured to each other. The ureters are reimplanted at the summit of each limb according to the mucosal groove procedure and the summit of the pouch is anastomosed to the urethra. This procedure has been used in 10 patients following radical cystectomy for cancer. Seven of these patients underwent clinical, radiological and urodynamic examination 5 months after the operation: all 7 patients were continent during the day. Nocturnal continence was obtained at the cost of getting up one or twice during the night, but incontinence persisted in the other 3 patients. Cystometry did not reveal any pressure waves greater than 25 cm of water for a volume of 500 ml. The detubularised ileal bladder is simple to perform and constitutes a reasonable alternative to traditional tubular enterocystoplasties.(ABSTRACT TRUNCATED AT 250 WORDS)
