Increase frequency of Urine. It.

I am having problem of UTI from last 1.5 years. I was suffering from problem of frequent urination so, took online appointment on Practice. They asked me to go for Renal function test and Urine culture test. Renal Function test was normal but Found Bacterial Infection in Urine Culture test. Doctor has prescribed Zifi CV 200. I took the medicine for two weeks. In the first the frequency of urination was normal but in second week again freuqnecy increase a little. Now, again the problem started. I started ayurvedic medicine like Chandraprabhwati, Gokshuradi Guggul and Giloy tablets from last two days but not getting any improvement. Now the urge for urination is also increasing. Please suggest me some medicine or treament for this. Now urge and freuqency also increased and feeling little fullnes in testicles some time if don not empyting it.
