Welcome to the other side RB!
I bought some of those temporary hooks that stick to the wall and peal off later to use on the shower wall to hang the catheter on when I took a shower. I stayed in a hotel room near the hospital until the catheter was removed so I couldn't mess up their tile bath tub walls.
It worked great and came right off. Be sure they are made by 3M, the ones that Walmart carry suck!
Ditto on the stool softeners. Good luck with your pathology report.
