I have been going through frequent urination and sudden urge to urinate isse. My urine routine shows 1-2 hpf pus cells and 8-10 hpf epithelial cells. Also, urine culture detected 30,000 cfu Klebsiella species. Sensitive to cefuroxime , nitrofurantoin and many antibiotics. I had completed a 7 day course of Cefuroxime 500 mg,  3 days nitrofurantoin which did not suit me. Ongoing the second round of Fosfomycin 3 g single dose + 7 days cefuroxime 500 mg, I don't have any other symptoms of UTI. I just have issues with constant urination. I am not able to recover with any of this completed course of antibiotics. Consulted 03 gynaecologist and 01 urologist. However, I don't get the solution for elimination of My UTI symptoms. Please , advice best medicine or doctor reference.
