I went to the Urologist today after repeated UTI's. After talking, I mentioned that I mostly use saliva as a lubricant. This was an old trick that I heard just after my accident. At any rate, when I mentioned this, my Doc about passed out. She claims that using saliva I might as well drag my cath along the floor of an outhouse? I never really gave it much thought, but, now that I think of it, I can see her point of bacteria in the saliva. Does anyone else use this method, and has it caused any UTI's??? Thanks, Mikey.
