Welcome, @drmarci. I agree with @sav1 to stay hydrated and physically active as you prepare for treatment. You may also be interested in joining these related discussions about urothelial cancer:

I'm sure you have loads of questions looping through your mind as you wait for your treatment planning appointment. I suggest keeping pen and paper (or phone) handy and jotting them down. Naturally, keep asking questions here. There are others here who have been in your shoes.

When will you find out about the treatment you'll be getting?
