Im a 40 year old woman, desperate to start a family, had 3 miscarriges, UTI was diagnosed Nov 05, urine cultured showed klebsiella, >100,000orgs/mil,sesitive to cefalexin and trimithroprim, since then these have been prescribed 7 times 1-2weeks at a time 250-500mg 3xday. I have even been prescribed a cefelexin 500mg as a prophylaxis, these antibiotics have had no impact on the infection, subsequent urine culture tests have shown I still have Klebsiella, with the same info above. I Was referred to Urologist,Cytoscopy normal apart from showing cystitis, scan of Unirary tract normal,a biopsy was done on the bladder, said I had follicular cystitis due to chronic klebsiella urine infection. It is a year on,recent urine culture still showing Klebsiella, Dr still prescribing same anti biotics, have tried altenatives like medicinal herbalist(been taking a herbal prescrition for 4 months) and watefall D Mannose (works like cranberry but stonger)My body clock is ticking cant put off trying for baby, but am afriad of the risks if I still have infection, and wonder if the miscarriages were caused by the infection (2 of my miscarriages were in the last year)where do I go from here? why are the antibiotics shown to be sensitive to klensiella not working? Can any body help me?
