Also, not so sure about that bicarb soda thing. I know it’s a raging controversy about alkalinizing the body to fight cancer, etc. but the human body’s homeostatic mechanisms usually keep the system at a pH of 7 give or take so will the urine become alkaline if you drink a basic solution? Perhaps, perhaps not.
People are always encouraged to drink cranberry juice to acidify the urine to combat UTIs so maybe there’s something there after all. Couldn’t hurt to try but all my experiences with catheters have given me maybe ONE very slightly burning urination the very first time after removal and that’s it.
