Also want to wish you the best in your upcoming surgery and recovery. My only advice is do those kegels as recommended by your care team prior to and after your surgery.
I also recommend that you get a few pairs of sweat pants to wear for a couple weeks following surgery. It made me a lot more comfortable and easier to deal with the catheter and bag. The catheter was uncomfortable as you would expect for a few days but wasn’t as bad I expected.
One thing I would add to catheter care; I would use a piece of athletic tape or gauze tape to wrap around the junction of the catheter and the tube going to the bag, I had an unfortunate incident with the tube coming loose st night while I was sleeping and the tape took care of that problem.
You will get ALOT of great advice here.
