May I congratulate you and your husband on seeking a second opinion!! This is so important..The best you can find out is that your current urologist is right on track. The next best is that if he/she isn't, what you can do instead!
Both places you mention, Kamnanos (Wayne State Univ.) and U. of Michigan are excellent choices, and I think it would depend on which is more convenient for you, geographically.
You want to be SURE that the doctor you consult is one of those who specializes in BLADDER CANCER. Many urologists spend 90% of their time on prostates.
Good luck to you.
