Status post kidney transplant , 17 years ago, due to PKD. Now having recurrent UTIs (14 in past 15 months), being followed by ID with plan to only treat if symptomatic since recent UTIs have been ecoli, resisitent to all oral meds and most IM/IV meds. However, patient does not have classic symptoms of urgency, buring, fever . Typically she starts to feels tired, becomes discoordinated and for falls. Then typically has decreased appetitie and fluid intake then has sypmtoms. Currently dipping urines daily. When uine s positive for nitrites, at what point should we be concerned about the presence of leukocyets - any, 70, 250, 500?
