I have an UTI too since 1 year ago, diagnosed as klebsiella p, which is almost resistant to all antibiotics.
I think it is in my prostate (where only a few antibiotics can reach there, how lucky am i?) , but it should be not as patogen as e coli or any other bacteria. Meaning it is not fatal unless you have severe neutropenia or immunodeficiency.
I have pain urinating for many months, and i think i got it with the last surgery i had.
Bactrim should be effective against it but it is the last card i can play and docs want to keep it if the infection becomes systemic.
Drink lots of water (i know it is hard with chemo but you can ask for an IV extra), and try to make your urines as much acid as possible (lemon juice , orange juice, vinegar might help), indeed bacteria try to create an alkanine environment to proliferate, so this might not solve the problem but will give bacteria some challenges to proliferate.
Please discuss it with a doc , every situation is different.
