I'm back from my bbq flank steak dinner. With rhubarb/raspberry (from our garden) pie for dessert. If you asked me some of the reasons I want to beat cancer, I'd have to admit that rhubarb pie would be fairly high on that list.
This very site has a pretty good definition of a neobladder:
blcwebcafe.org/neobladders.asp
The short version is that after your bladder is removed, the surgeon takes a couple of feet from your intestine and makes a new bladder (neobladder). I can't sugarcoat the procedure; it's major surgery and takes some time getting used to. But I'm happy with mine, and haven't had any complications or problems.
Believe me, you aren't worried before your time if you're seeking knowledge and advice to help you make a decision. And everyone here is happy to help you as much as we can.
But don't worry and become fearful. That's not only counterproductive, it clouds your thinking and can really dominate your whole thought process, like weeds taking over a garden if they're allowed free reign.
Best wishes--Zach
