Continent sigmoid bladder after cystectomy: 20 years' experience.

Twenty years' experience in the substitution of an isolated sigmoid segment after radical cystectomy for bladder carcinoma is described. The indication for surgery was isolated, non-transitional cell bladder cancer. The isolated sigmoid segment is placed longitudinally in the isoperistaltic direction. The study is made up of 73 cases. This operation does not make the procedure more radical since it does not increase survival for this illness. However, in relation to other bladder substitution methods, it guarantees a better quality of life after the operation.
