May seem like a stupid question - but are you sure you have a UTI -
meaning has your urine been sent out for culture? There can be UTI
symptoms without bacteria. A thing called interstitial cystitis
mimicks UTIs almost exactly, feels better with antibiotics, but comes
back after because it is not really a bacterial thing. Also,
endometriosis on the bladder can give symptoms of UTI.
So worth asking before you really get into thinking about surgery. All
the best, Judy
