I had a similar experience and was convinced I had a UTI as I had 3 of them after my biopsy before surgery, the last 2 weeks before surgery. MY URO tested my urine which came back negative and told me it was just the irritation from the sutures and healing of the attachment of the urethra to the bladder. It finally went away after the third week about
the time I became fully continent.
I do enjoy being able to pee like a teenager again. I can go into a public restroom at the same time as another man with a prostate and empty my bladder, wash my hands and exit while the other guy is still unzipping his fly
