Dean,
It really is an "it all depends". My very first TURBT, I had a catheter in for almost a week after. That was October of 2006. I have a home office and was able to work on and off pretty much every day. I didn't do any work the day of the surgery, only a couple hours the day after, and then about 6 hours a day for a couple of days. I was on a plane traveling a couple days after getting the catheter out. I believe I did have some urgency issues for a day or so after catheter removal.
The next one was about a year ago and I was in early, out right after waking up in recovery and had no catheter. Was able to be online working from home same day. No urgency issues.
When I had another one in September of last year, they did more (TURBT, plus brush biopsies of ureters and kidneys, plus TUIP) and I had no catheter at home and was pretty much right back to doing everything within a couple of days. I had an overnight stay that time because my surgery wasn't until late in the evening. No urgency issues.
First time, I took pain meds for 2 days but kept them to a minimum. Second time, I didn't really feel like I needed any pain meds at all. I think I may have taken pain meds the day after the third one and maybe the following day.
All 3 times there was blood afterwards for a few days or so.
For work, I think it is probably better to set worst case expectations and then be back up and going sooner than you set expecations. But if you are sales management, you already know to set expectations that you know you can exceed.
Good luck!
Mike
