Mc,
I have to plead ignorance about the Florida pouch. Long ago I decided that I was never going to be, and could never be, an expert on bladder cancer. When I read about different diversions or chemo protocols, my eyes glaze over and I often skip them. I'm officially out of the market for procedures. Once you've had yours, there's no since looking for a better one. I have a friend who has never bought a computer printer because he keeps waiting hoping something better and cheaper and faster comes along. This has been going on for ten years! I think we should decide, do it, and not look backwards.
What I am an expert on, though, is my particular situation. I have a neobladder (I'm 51, by the way) and have no difficulties with it. In the beginning there was a learning curve, but with a few months I was fine in the day-time. Nights were another matter; I had an additional surgery to install an artificial sphincter and now I'm fine all the time. In time--that's the operative statement--everything new becomes a normal part of your life. My neobladder is a little different than my old bladder, but I'm so used to it now (after a year) that it's second-nature. It requires absolutely no thought. It... just..... works.
If you do go the neobladder route I think you'll be pleased. If you go the Indiana route I think you'll be pleased. Likewise with the Florida pouch. The Rhode Island pouch I'm not so sure of.
This is my short-winded way of telling you that I think you'll do well with whatever you and your surgeon decide on. Of course you've read many posts here on the importance of finding a surgeon who has done many of these procedures.
Best of luck to you.
