Comparison of Orthotopic Sigmoid and Ileal Neobladders: Continence and Urodynamic Parameters

A neobladder constructed from detubularized ileum or sigmoid achieves adequate capacity with a satisfactory daytime continence rate. Nighttime incontinence in patients with IN can be at least partly explained by periods of high pressure due to neobladder contractions in combination with a relaxed sphincter during sleep. The low nighttime continence rate of the SN is probably related to its small functional capacity.
