Welcome to the forum. I fully understand feeling like your head cannot hold another bit of information from reading everything you can find about BC and treatments.
I just wanted to say that I am a Vanderbilt patient and had surgery there in February 2010. I did not have my bladder removed, but did have a partial resection of the wall where my tumor was located via open surgery. I do not have any info on their robotic program, but it is discussed on the Urology Department website Pat provided.
My stay was short compared to what your husband will have if he has a cystectomy... only 4 days for me. But, I was very impressed with the care I received. They are a teaching hospital so there were always interns/residents coming by to check on me. If I ever need another surgery, I will go back there without hesitation. There are several hotels near the hospital that give reduced rates for VB patients.
I still go there for my followups even though it is a 300-mile drive. As a matter of fact, I'm going back on Monday for my first 6-month interval cystoscopy and a CT scan. My urologist/surgeon is Dr. Cookson, and as Pat pointed out they have a very talented surgery/oncology staff.
I hope you are able to make a choice soon that you are comfortable with... at least as comfortable as it is possible to be at this point.
