How do you get answers to the questions you have? YOU ASK! After your meeting with your new doctor, IF you feel comfortable with her and IF you feel that this is a place that you could see yourself coming for treatment/surgery, and after you have reviewed the treatment plan, make a list of all your questions. For example, you may say "We understand that it is important to have a surgeon who does a large number of these surgeries...How many do you do a year?" Also ask what diversions the surgeon uses (a general urologist who does not specialize in bladder cancer often is only competent to do the simplest, the ileal conduit.) If the doctor does not discuss these questions willingly, you need to move.
You have probably read in other threads here a comment ..."you wouldn't take your Lamborghini roadster to a Chevy dealer for service" and your life is at least as important as a Lamborghini! Medical care is a service for which you pay, and it is your responsibility to "check it out."
The "latest" thing in bladder surgery is the robotic or da Vinci device where the surgeon uses a remote device that minimizes the extent of the open exposure during surgery. This can be an advantage, BUT again, it is the experience of the surgeon, not the device used, that makes a difference. Since the procedure is relatively new, it is again critical that the surgeon have a lot of experience with it. A friend of mine who is a urologist recent spent a YEAR training in robotic surgery before she went back to practice. I would rather have traditional surgery by an expert than robotic by a novice!
You also may find that the type of diversion suggested will depend on your husband's condition and the position of the tumor in the bladder. So you will need to judge whether such a recommendation is because that particular diversion is the only one the surgeon does, or because of medical reasons.
A lot to think about, but with your attitudes you will do fine.
