Like you, I have been self-cathing 4-5 times daily for several years now. No UTI's since beginning (thankfully). My "what are others experiencing from self-cathing" questions include but not limited to: "flow" issues when emptying bladder i.e., sometimes abruptly stopping (as though the bladder did NOT seem to empty fully) and sometimes strong, to mild, to dripping flow (seemingly indicating that the bladder DID fully empty).
Other issues? For me, the experience of cathing in public restrooms (especially when crowded e.g., sporting events, concerts, etc.).
Sharing, or not, with others Family/friends the fact that this is a lifelong reality. 🙁
Other questions, concerns, experiences?
Personally, I am hoping to find a "community/support group", maybe this is the place for like minded individuals to share their concerns and experiences.

How did you get the repetition of UTIs under control. Is there a long-term solution?

Did you find a long term solution to avoid repetitive UTS?
