I was unknowingly headed in the same direction as the OP. I had all the standard symptoms but no pain. After breaking my hip an X-ray showed a glowing mass were my around the prostate area. An orthopedist looking at that and some lit up areas on my undamged hip said it looks like you have prostate cancer that has metastasized to the hip. Scared the shi** out of me. The urologist immediately recognized the glowing mass as a bladder stone - on the scope it looked like some kind of giant alien artifact. I ended up having the stone removed and a TURP like the OP (roto-rooting the prostate) to imporove flow and avoid recurrence of the stones. It worked well for me - only one trip to the john per night. And I was quickly back on the bike.
