Gina,
The odds are that it will work! It is just statistics though, meaning everyone is different as our bodies all respond different and everyone's cancer is slightly different. All I can say is most if not all of us have been through this and the majority have been fortunate to have it work. Until that first check up you really don't know, and remember my concern just like you. If not, life will and can go on without the bladder. I have tried to prepare myself mentally either way. Keep your time and life full of family or activity-after all-that is what is important.
