Kim,
Welcome. 1st, you are asking the right questions. also, pat yourself on the back as a caregiver because all diseases have better results with family/friends making a team!
The first part of your thread! You have had the most important tests as a start: cystoscopy, CT scan and to a lesser extent ultrasound are the gold standard of tests. You still won't know much until the TURB is done and pathology reads it.
I have read good things on Dr. Chamie. And, UCLA does have a good reputation. People that compile lists also have their viewpoints and agendas! You just want one that sees a lot of bladder cancer as opposed to prostatic groups. UCLA I believe has a specialized group for bladder. Here is a list:
health.usnews.com/best-hospitals/rankings/cancer. Like Sara Anne I do like University settings and teaching hospitals. They are usually are on the cutting edge of things!
IF you are encouraging MD Anderson and it is more convenient, it is my backup and does rank #1 on this list plus I live in Texas. I have firsthand accounts from 3 people I know well that will vouch for them. UCLA, MD ANDERSON or another big group will serve as a second opinion as they will probably either repeat some of the tests or the TURB will give you confirmation.
