Twenty seven patients treated by Hautmann enterocystoplasty completed a detailed questionnaire concerning the quality of their micturition and continence. The mean capacity of the neobladder was 250 cc with a diurnal interval between micturitions of about 3 hours. 79% of patients experienced an urge to micturate. The mean frequency of nocturnal micturition was 1.6. Diurnal continence was perfect in 100% of patients, while nocturnal continence was excellent in 78% of cases and good in 18% of cases, while one patient (4%) suffered from nocturnal incontinence. Hautmann enterocystoplasty is therefore an excellent technique for bladder replacement, ensuring diurnal and nocturnal continence for the great majority of patients.
