Having a catheter is no big deal. You will learn fast how to take care of it. You get a night bag and a day bag. Drain leg bag often. As soon as your pain decreases do kinda what you can. No heavy lifting. 10 days is nothing. I had one for 25 days after ED visit and 6 days in hospital. 40 hyperbaric visits to stop bleeding. Radiation cystitis and radiation proctitis can happen after radiation. I have had way too many catheters. A catheter may slow him down but life goes on. Leave him alone. Good luck. Mayo library has many things to watch on catheter care.
