Wawawanye,
Hox makes an excellent point. When things go wrong, they can go very, very wrong.
That is why it is critical to have a surgeon who does LOTS of neobladder surgeries every year. At least 50 a year but the higher the number, the better. These are typically found at the top teaching hospitals. Memorial Sloan Kettering, MD Anderson, Johns Hopkins, Cleveland Clinic, Vanderbilt, to name a few.
Do NOT get the surgery with a local uro or somebody you think is a 'nice guy'. Surgical skill and experience are what matter most.
Best of luck to you in your surgery.
Mike
