My mom has a recurring UTI e. Coli. First occurred in march 2016 treated with nitrofurantoin for 2 months but came back mid may with low grade fever and culture showing e. Coli sensitive to chloramphenicol, amikacin and sporaflxacin and partially sensitive to ampicillin/sulphabactum, tobramycin, augmentin. She has renal impairment with creatinine at 1.64, Urea is normal. She has undergone a heart bypass a year and half ago, is diabetic which is under control with medication and hypertensive also which fluctuates and she is on medication for that as well. This recurring UTI resistant to most antibiotics is worrying and the one's its sensitive to are not recommended because of renal impairment and her history. Any advice would be helpful. Thanks.
