Also a Brassard girl here. I also get very frequent UTIs, mainly from wearing diapers. My urologist thinks it is how the urethra graft healed. My partner, who went to another surgeon, her urethral graft healed almost perfectly, mine... didn't really. I've pondered exploring seeing if there is any way to revise the urethral graft, but my urologist is also super worried it may make things worse for me. In the mean time, I have a daily low dose of trimethoprim which has largely helped keep UTIs away. I was actually REALLY lucky for a couple years, and didn't get any UTIs until I decided to take a bath while on a business trip overseas.
Welcome!
I hate to even think about this, but it is not exactly... uncommon. I fear long international flights because typically I'll leak a little, and really don't want to try and wear diapers on stupidly long flights.
