I can't speak for the Sphincterotomy surgery , But I used to use a Foley and Like you even though I kept great care to keep clean and Sterile I ended up with some severe Uti's and one even turned into a severe kidney infection that was the sickest i have ever been in my life, I made the choice to wear diapers to manage my bladder and have never looked back. wearing diapers 24/7 can be a pain but it's also been very freeing at the same time. one thing for sure i have almost no UTI's wearing a diaper and the very few i have gotten have been so minor they cleared up without treatment.
