Objective To analyse, in a retrospective study, the oncolspontaneous voiding, with a mean pouch capacity of 720 mL. Daytime continence was achieved in 88%, ogical outcome, pouch-related complications, continence and micturition after radical cystoprostatectomy including 17% wearing one safety pad; 9% had stress incontinence and 3% total incontinence; 67% could combined with Mainz pouch orthotopic bladder substitution to the urethra for the treatment of bladder sleep through the night, with either complete continence (34%) or one safety pad (33%). Nocturnal cancer.Patients and methods Between 1986 and 1996, three incontinence occurred in 11%. Uretero-intestinal stenosis occurred in 15 of 205 (7%) renal units, requiring urological departments contributed 108 male patients to the review. The same exclusion criteria from orthoureteric reimplantations in 11, nephrectomy in three and antegrade dilatation in one. Reflux was not noted topic bladder substitution were applied by all centres, i.e. multifocal or concomitant carcinoma in situ, in any patient. About half the patients were on antiacidotic prophylaxis. tumour at the bladder neck, positive biopsy from the prostatic urethra, locally advanced tumour and lymphConclusion The large bowel segment in the Mainz-pouch technique of orthotopic bladder substitution provides node involvement. In all, 103 patients were evaluable for follow-up, with a mean (range) follow-up of good reservoir capacity and continence rates, with less ileum used than in all-ileum pouches. The surgical 42 (3-132) months. Results Pathological examination of the cystectomy technique is simple and reproducible, and in particular the antireflux ureteric implantation into the caecum specimen revealed 81% organ-confined tumours. During follow-up, 84% of patients remained free of protects the upper urinary tracts. Keywords Bladder substitution, bladder cancer, ileocaetumour, 7% developed distant metastases, 5% local recurrences, 4% urethral recurrences, and 1% upper cal pouch, outcome tract urothelial cancer; 85% of patients are capable of reconstruction of the lower urinary tract are protection
