hi lapilot,
I had my surgery on sept 26th and my cath removed 9 days after, like you I was wondering if I should buy some supplies but then thought if I need them i'm sure the uros office will have samples, so I didn't. when the nurse pulled out the catheter nothing leaked I was shocked when she said ok you are all set I asked her if I needed a pad or something she said no you're done. so I left a little nervous that I might have an accident but never did (I lost a few drops after a sneeze the second day but that was it) anyway hope for the best, I don't think they would let you leave without protection if you need it. I should also add that I have been walking 2 miles a day for as long as I can remember but stepped it up to 3 for the month before surgery and since, a lot of the guys here said that walking was good for continence, anyway I figured it couldn't hurt.
see you on the other side
hope you have a speedy recovery
