Sorry you are having to go through this. I know how frightening and frustrating it can be.
That is a great question about the scope not being filmed. Perhaps because it really isn't used for diagnoses? I am sorry I don't have that answer.
After much reading, I know many here send their pathology in for a second opinion, but not results of a scope. I hope someone has the answer for you.
Your TURB is scheduled for this Wednesday? Then the wait for pathology ... from there you will be able to make your plan.
Wishing you the best of luck.
