I have fever, chills and diagnosed with UTI. Please suggest a better way to treat it.

Hi doctor,

A month back, I had a fever and chills. I was diagnosed with UTI. My doctor gave me Cefixime 200 mg two doses for seven days. It did not help me. After two days, it got resolved by itself. After a week, I started to have groin pain, suprapubic pain, kidney pain, burning sensation during urination, reduced urinary frequency, and a few drops of urine dropped during urination. They gave me Azithromycin and painkillers. After two days, I had vomiting and chills. Again I consulted a doctor. He gave me Sultamicillin 750 mg with painkillers for three days. Currently, I am taking Sodium bicarbonate and Ofloxacin. My ultrasound shows renal parenchymal disease and my creatinine remains high. My CBC shows that I have an infection and urinalysis also shows that I have an infection. I took this last week. But in this week, only monocytes and creatinine remain high. Is there any other way to treat this condition other than Sodium bicarbonate and Ofloxacin?
