Here is the first report on 5 different types...there are many more and its important to ask your surgeon exactly what type of diversion he is doing and what part of your colon, how much of your colon, and if he's using the ileal cecal valve. He also will not tell you about eventual Bl2 deficiency.
Most investigators have reported on a single type of diversion. Over the years, Santucci et al. [8•] have suggested that a variety of configurations might be appropriate and therefore have constructed five different continent urinary reservoirs when required. They reported long-term continence rates and compared urodynamic results in a series in which the senior surgeons performed a variety of different continent urinary reconstructions [8•]. Stomal urinary reservoirs had the best continence rates (Indiana pouch 100%, Mainz pouch 91%). Neobladder continence rates were as follows: Hautmann 80%; Mainz 75%; sigmoid 50%; and gastric 33%. Compared with the other pouches, gastric and sigmoid reconstructions had the smallest capacity, were the least compliant and were the most contractile. Stomal urinary reservoirs using ileocecal valve and right colon, with or without an overlying patch of ileum, provided similar excellent results. Continence approached 100% in compliant patients without the need for revision. Patients with neobladders were less continent, although those with ileal or ileocecal configurations still had very good continence rates. Neobladders of sigmoid or stomach can be used when necessary, but with greater incontinence rates. This poorer continence can be explained by the decreased capacity, decreased compliance and a tendency toward high pressure spikes despite detubularization"
