My 61 year old long term diabetic mother is in hospital since last 10 days with UTI and Hydronephrosis. She was on antibiotics like Nitrofurantoin, fosfomycin and ceftriaxone IV. But despite 10 days prolonged treatment she is getting chills and fever and WBC count is 17000. Doctor has now started Meropenem and recommended a delayed urine culture test. Her sugar has been brought under control with insulin. We are scared and not sure if treatment given is proper. Please suggest if we should consult another hospital or doctor.
