Good luck!
I'd reccommend a couple of kinds of surgical tape. They have all kinds at the hospital, but I also got my own at home. It took me a day or two to figure out how to "arrange" the catheter tube for maximum comfort, and less tugging. Big baggy, silk boxer shorts seemed to work the best.
I didn't have the Davinci procedure, mine was tradtional. I'd recommend seeing if the doctor will give you your prescription to pain killers BEFORE you check out so you can get it filled at the hospital pharmacy. I was on a demeriol dirp all day, but it wore off before I could get my vicodin filled....kind of hurt....maybe the daVinci method is less painful (mine wans't that bad, and I was off pain killers in a week).
For post-hospital, if you can get your hands on a walker (the kind with wheels on the back), get one. It's perfect for hanging the night bag of the catheter. You don't have to screw around hanging it on the bed and its a lot easier to move around the house without switching to the leg bag. Also, I found having a little plastic bag to put around the catheter bag was a good idea, too. Thay way my wife and daughter weren't staring at a bag of urine when I was in the room.
You'll do great....just warm-up the la-z-boy at home and you'll be back to normal before you know it!
