I had RALP last August. I took about 4 weeks of Pelvic Floor PT prior to surgery and 4-6 more weeks after the surgery. I wore the diapers from when I got home until a few days after catheter removal. I had ZERO incontinence. While this does not relate directly to a return to work, but, to me, a return to work is more about when he is ready and being continent may help him considerably. Good Luck!
