The hydraulic ileal valve, which we developed in 1975, ensures contine
nce by adaptating to 5 different urinary reservoirs. An isolated ileal
segment (14 cm) is folded inward on itself throughout its entire leng
th. We performed 260 continent urostomies. An ileocecal reservoir was
used in 179, detubularised ileocecal reservoir in 32, ileum 34, sigmoi
d 5, rectum 1 and bladder (continent cystostomy) in 8. Of the patients
82% were continent immediately. Continence was obtained after repair
of the valve in 12.5% therefore, 94.5% patients over all were continen
