I had a TURP nearly 6 years back. Peeing was bloody and painful for a few days, but once over that the improvement was immediate and amazing with no side effects.
Another 'benefit' of the procedure is that the extracted tissue is examined and in my case, that is when my PCa was discovered. This led to me going on AS and eventually having RALP last year. Without the TURP, my PCa may well have progressed unnoticed. Of course, I am not suggesting TURP as a diagnostic tool for all.
A slight downside of TURP is that should you ever need RALP, you are definitely in for a bladder neck reconstruction. In my case and thanks to the skill of my surgeon, I have to date suffered no issues because of that.
I was never offered Rezum. Perhaps it was not around in 2017.
