I had bladder cancer.
My surgery took about 6 1/2 to 7 hours with the reconstruction of the neobladder. You will loose weight but don't worry it comes back as you get stronger. I was told that it takes about 1 month for every hour of surgery to get back to normal and believe me it will. You will not be huingry after the surgery. make sure you drink plenty of liquids.
Ask what type or pouch are they using. At USC they have the T and the koch. Apparently they both work well. I have the Koch and I know someone that has the T.
If you are a female I know a lady in Detroit that had the surgery. She is doing great and is very happy. As a male they also take the prostate as a female I believe they remove the female organs you better ask.
Also if you are a male they can do a peniel inplant that works very well. You should ask.
If you want to know anything else let me know. Hope all turns out OK for you. There is light at the end of the tunnel.
