Sorry to read this, poor you I don't have that, but I have to say that before being diagnosed with endo (in April this year) - I kept getting UTI's. And when I say 'kept getting' I mean - I have 13 over 12 months. I was literally on antibiotics loads to the point where the doctors were worrying about my building up a resistance to them. Anyways, the gynae. (before exploratory lap. was done) said that maybe there was endo on my bladder, causing this to happen.
I had my op. - was riddle with endo (their words!!) womb was really tilted due to it pulling on it and both ovaries and fallopian tubes were stuck to my walls by it. BUT, I spoke to the surgeon who performed it and he said there was endo near my bladder, there was a lot but none in that area. So I am totally miffed as to why I kept getting them. I drink a LOT of water etc so I was hoping it was endo related.
Having read your post though, I'm starting to think that endo. is causing it? Having said all this, I've not had a UTI for a few months now *touchwood*
Hopefully someone else sees your post and is more helpful than me! But I felt I should reply as the whole UTI thing was really getting me down, I was always in tears as sometimes it was really, really bad
