Mark - 10 years without my bladder.
Everyone has an opinion on which path to take when faced with a cystectomy. I took the "neobladder" approach. Couldn't be happier. No external bag, no issues with incontinence or over-active mucus production that could potentially block the urethra.
At the end of the day, your way forward will be based on what the doctors find when they open you up as some folks have cancer in their urethra and therefore are not eligible for the neobladder. But that is typically an in-surgery call once they see what they are dealing with.
I also had a small spot of cancer in my prostate so they took that as well.
Success is a function of your particular situation (spread of the cancer, etc.), the skill of the surgeon, and most importantly in my opinion - your patience and attitude.
Good luck - let us all know how you come out the other side of this decision.
