Urology :: Lactobacillus In Urine?

I am a 32 year old female. With Polycystic Ovarian Syndrome, and otherwise very healthy, except for a recent issue this summer with C.Diff/Clostridium Difficile after being given Augmentin antibiotic for bronchitis back in May. It killed all my good bacteria.. and have been on Flagyl and Vancomycin to treat the c diff damage Augmentin did. Back on Vanco a 2nd round.

Anyways, a month and a half later after the cdiff started, I developed this weird "burning" sensation around and inside my urethra. I had no idea what it was. Never had a UTI before that I know of. Then, I noticed these little "specks"/particles that looked like teeny little skin flakes in my pee and sometimes its cloudy with it... and weird little "bubbles". there were 4 occasions.. where something that resembled a shred of lettuce, very small, but looked, like.. lettuce, even the little veiny lettuce leaf things... came out during urination. oddly, i had lettuce the day before 2 of those events. I am pretty sure it came out with my urine, as the toilets were perfectly clear beforehand... and it happened at my work toilet and at home. and i did not do a #2 during any of these incidents. these were all in afternoons/evenings. and i normally only have BM's first thing in the morning. even with cdiff. i never saw such a thing in my pee before. then again, i never exactly looked all the time at my pee. until the burning thing started... then yeah, i was paying attention.

So, I do not have insurance, and was under the care of a Gastroenterologist at the main city hospital for the cdiff and he was letting me see him for free for 3 appointments as a courtesy thing. So, I told him how I thought I had a UTI, and if I have a UTI, I am in BIG trouble because that means I would need an antibiotic.. and I cant be on any other antibiotics as it would cause me to have a major c.diff setback or even kill me.

So, he ordered me to get a Urinalysis by Microscopy and Urine Culture test at the lab downstairs to their office. The urinalysis came back all normal/negative.. except trace ketones and trace mucus. everything else was fine. Urine culture came back and no Leukocytes, etc. BUT... it had 3 bacterias.. but within "normal limits". it just said "#1.. gram negative rods 2,000 count #2. gram neg rods 3,000 #3 Lactobacillus species 50,000. colonies per ML. Lab paper just says most likely sample collection contamination due to the mixed bacterias found. repeat if they wanted to. and that was it. doc said they don't treat unless its over 100,000 colonies. and they considered it a non-UTI. is this correct?

So... question is... is this actually even an "infection"??? The burning went away for several days, actually.

BUT I am currently taking probiotics.. for the cdiff treatment. LOTS and lots of Lifeway Kefir...which contains.. lactobacillus.........

so, could this be that its somehow getting into my urine? or... vaginal contamination how i did the sample collection? just funyn how it happens to be.. just that bacteria.

I know docs thought perhaps I may have IC back in 2007, but was never tested for anything. That was after I was having chronic urination... im talking 20-30 times a night. AFter they ruled out other problems and diabetes.

Also, can baking soda help fix this "problem"?
