I feel ya....as the young folks say.

I always dread the cysto and also the maintenance treatments but in reality it is more mental for me than physical. Although I don't think my prostate will ever be the same as it was prior to diagnosis. I can honestly say that after going to the 6 month cycles vs three month my sex life has improved almost to normal (for a 70 yo).
In my case (not sure everyone has the same experience) I watch intently on the video screen as my Doc looks around my bladder making comments like "that's scar tissue, that is the left ureter, that looks like the BCG is working, that's the right ureter, your prostate looks inflamed", etc.
My Urologist is pretty cool. He has over 30 years experience, is calm, not the greatest bedside manner, but let's you know that you will be OK and he will make sure of it. The one thing I find semi-annoying is that the Med Techs that give me the BCG seem to change about every treatment cycle. It is embarrassing enough without seeing a new one every time (What up with that?)
Peace and Love,
Dave
