Hi Paul,
I have just had the OP exactly 1 week ago today, I too had quite a large prostate and only had 2 options, prostatectomy or RT, I decided on the OP as I wanted it out and as far as I know a lot of surgeons will not operate after RT, anyway the OP was nowhere near as bad as I had imagined it would be, the worst was the gas which they pump into you for access to the prostate, a few good farts and things were a lot better, catheter not really a problem it is nice not to have to get up at night, going to go out for a walk today, just take one step at a time there is no rush,
all the best for your OP,
Paul
