I m 35 yr old Male that had two UTI s in the space of a fortnight. Ultrasound of Kidney s & Bladder both came back clear. I was also given a PSA blood test in the first seven days of taking antibiotics for the second UTI. The result came back at 12.6 so was referred to a consultant urologist. He was confident this was caused by the UTI s, and sent me for another PSA blood test (roughly two weeks after the first one), and around a week and a half after the antibiotics finished. The reading had gone down to 10.1. How long would it likely take to return to normal assuming there is no other underlying cause?
