My biggest fear with my high dose brachytherapy surgical procedure was the urinary catheter placement and removal. At my strong request, they waited for me to be anesthetized before the inserted it so I felt nothing of course. When they removed it post surgery before I was discharged....the nice nurse gave me Fentanyl in my IV and I did not feel the removal either.

That said, I have a friend who has been treated for bladder cancer and had multiple urinary catheters that they give you numbing medicine before they insert it and he said it was not bad at all.

Good luck to you.
