Hello Bambi,
Don’t waste any time if it is G3, if it starts to spread it can do a lot of damage and prolong treatment. Dr Shandra Wilson CU Aurora is very good and one of the nicest doctors you’ll ever meet.
As far radical Cystectomy and diversions, there are three. The first is a neo bladder which uses part of the lower intestine to create a new bladder and uses the original plumbing, requires potty training and a regiment to stretch it to a specific volume. The second is called an Indiana Pouch that is similar to a neo bladder, but instead of voiding normally, there is a valve placed in the belly button and a catheter is used to void. The third choice is the ileal conduit, it uses a very small amount of the lower intestine, just enough to connect the ureters to the abdominal wall to use an external bag.
Again, don’t waste any time for second opinions or referrals.
Bill
