Dysuria problem. Treat this infection?

Hi doctors, my mother is 54 years old. She is also a diabetic patient. She is having dysuria issue for almost 3 years. And it occurs sometimes in the gap of 7-8 months. Few months back when she wento to urologist they said after urine report that it is infection and they have given some medicine and it was fine within one week. Can she repeat same medicine now because it is repeated and we have done urine and blood test so it says infection. Can we repeat same medication as that doctor is not available in the city for the past few weeks. I have attached the urine and kidney function report also. Can you please tell if her kidney is fine? What medication she can take to treat this infection? Please answer and give helpful reply. Its urgent. Thank you.
