Is pcr helpful for me. Your opinion!

I need your opinion regarding my long-term urine problem. - Around 3 years back, I started having burning sensation while passing urine. - Initially, urine culture was positive, but bacteria kept changing after every antibiotic course. - Later, urine culture showed no bacteria, but symptoms continued (burning sensation). Then my doctor did prostate massage, and after that: - Post-massage urine culture came positive for bacteria. - I completed the full antibiotic course, but burning sensation did not fully go away. Recently: - Doctor again did prostate massage, but this time culture is negative. - Uroflowmetry – normal - USG before & after urine – normal - Doctor tried some medicines, but burning sensation still persists. Now I am thinking to ask my doctor for PCR urine test to detect bacteria. My questions to doctors: - Is PCR urine test useful in such cases? - Any other tests or approach you suggest?
