Urinalysis: Sounds like you may have had upper urinary tract infection without spillage of inflammatory cells into the renal calyx, so that although the bacteria showed up the inflammatory cells did not. The other alternative is that this was somehow a contaminated specimen and the e. Coli were not from the urinary tract.
