Throwing my hat into the ring

Alright folks, here’s my situation:

Recurring UTIs for the past 6 months. Most of the time I get cultures back it’s salmonella, though lately I had citrobacter youngae and E. coli. I’ve been on bactrim, keflex, cefdinir, macrobid, hiprex, and rocefin shots. They take care of the symptoms while I’m on them but about 3 days later the symptoms come back.

The good news is that ct scans show no stones or abnormalities in the abdomen and the problem seems to be localized in my bladder. The bad news is I have moderate trebeculation in the bladder, post void retention of about 150 ml, and low urine flow. I’ve been on flowmax and that doesn’t seem to help much.

I’m drinking contrast tomorrow to see if I have a bladder fistula, but he didn’t notice anything on the cystoscopy. I worry that if nothing shows up tomorrow I’m back to square one. How do you all live with this?
