Have had a recurrent or relapsed uti that has been cultured twice and positive for klebsiella pneumonia and group b strep . Given 4 different meds for 1 week at a time ( macrobid , cipro, levaquin , augmentin and now back on cipro), gets better while on meds but returns within 2 weeks. What is the next step -- long term meds and if so which ones (allergic to sulfa drugs). Had ultrasound of kidney and all was ok. As well as test for urethra stricture-- ok. Please help--frustrated!
