Gabriel,
When I had my first TURBT they noticed lumpiness with my prostate. Didn't say "stony" but they did say I needed it biopsied. My thought was "Why the hell didn't you just do that while I was under for the TURBT?". Anyway, they biopsied all over the place and it was fine for me. I'd had multiple occurrences of prostatitis and was biopsied again a couple year or so later and still no prostate cancer.
If your dad gets the cystectomy, the prostate comes out anyway so it kind of depends on how soon he can get that second opinion on the bladder.
If he's not getting a cystectomy in the very near future, then definitely the prostate needs prompt attention. If he is getting a cystectomy in the very near future, then they can dissect and study the prostate all they want since it won't be in his body anymore.
It could also be that the bladder cancer has spread to the prostate. That would actually likely be better than if it is a primary occurrence of prostate cancer.
He really needs to get on a plane and get to a top bladder cancer doctor right away. Both need to get figured out like right now!
