I am very sorry that you are here. But do hope that you can find some answers.
Many physicians sort of tailor their discussions to what they feel the patient wants to know. Some of us make it clear that we want to be in charge of our treatment and our conditions and we seek out doctors who appreciate this. Other patients do not want to know "too much" and, therefore, doctors do not give them too much information.
If your brother wants more information, he should make it clear to the doctors. He should make a list of questions to take with him; it is also a very good idea to have someone go with him, since it is difficult to stay focused and a second pair of ears is very useful.
For myself, I want to know EVERYTHING the urologist knows about my condition; I ask for, and get, copies of all pathology and other test reports. IF a doctor were resistant to providing these, he/she would not remain my doctor.
Depending on where your brother is being treated, it might be a good idea for him to get a second opinion at a center with specific expertise in the treatment of bladder cancer. If you let us know where he is located, we can make some suggestions. Or, on our Home Page, click on the "Help" tab...there is another tab that says "Researched Resources"..click on that and there is a geographical list of such places.
Of course, it is up to your brother as to whether he wished to take this advice. But you can certainly serve as an advocate and adviser to him.
Best wishes to you all.
