[Rectal neobladder. A 25-year experience].

On the experience of 153 cases of rectal bladder after cystectomy for cancer, the indications, technique and results of this operations are reported. Earlier, it was a method of choice as a bladder substitute. Today the indication is limited to female cysto-urethrectomy. Technique consists in rectum isolation and ureterorectal antireflux anastomosis; the sigmoid colon is pulled through behind rectum and between outer and inner layer of anal sphincter fixed on the perineum. The overall postoperative mortality is 7.8%, but in the last 5 years there was no mortality. The most frequent complications are sigmoid retraction and its partial necrosis. Micturition mostly is under control, but 14% of patients have a relative defecation incontinence.
