UTI & Kidney Stone And Reinfection.

I had a kidney stone (4.0mm in size) as well as UTI causing lower abdominal pain, frequent urination and bloody urine with burning sensation in last year, 2016 and the stone was flushed with urine through more water intake during under the treatment in local hospital. My doctor prescribed to take antibiotics intravenously, some syrup (Potrate SF) and tablets to fight UTI and Stone symptoms. After fifteen days, I was completely out of problem and remain same up to 11/05/2017. But, on 11th May' 2017 I have felt same strong urge to frequent urinate with almost no urine and the back pain throughout the night. In the next morning I have consulted with my local doctor and he prescribed some oral antibiotic tablets for five days along with Potrate SF and other medicine. Now, all the pain and frequent urination has gone and I feel quite well. However, I am afraid of reinfection again in the future. Is there any really good option to reduce the chances of UTI and kidney stone in the future ?i
