Karen,
It is very good and kind of you to help a friend out in need.
A lot of how your friend is going to feel will depend on the type of anesthesia that he gets. There are generally 2 types...
1. a general anesthesia, where it may take him a good while to really wake up, and generally feel pretty lousy for awhile.
2. An epidural, which is much easier on recovery, but can cause intense headaches if not administered correctly.
I'm not a guy, so I'm not sure how long the catheter will have to stay in. There was not much bleeding or pain experienced with my 2 TUR's, but some people do experience bladder spasms, so make sure that he gets some meds for spasms, just in case.
He will probably be given an antibiotic to take with him also.
I had a biopsy in Chapel Hill under an epidural with a twilight drug, and rode home for the 3 hour trip on the same day. Needless to say, I laid down in the back of my sister's van and went to sleep. Not much company for the trip, I'm afraid.
Thats about all I can think of.
Maybe someone else will remember something that I've left out. Good luck. Hope the VA is good to you both.
Your friend,
Rosemary
