MrB-
As I said, I think it is a mistake to ask and to take advice about
one specialty from a doctor in another specialty. That goes for a specialist in one kind of radiation opining about
a technique he doesn't use. I suggest you talk to the SBRT doc and hear for yourself what an actual practitioner with experience at it has to say.
Of the surgeons... Some are just blowhards, but that doesn't mean they are bad surgeons. I'd assess them on:
• The # of RPs under their belts
• their positive surgical margin rate
• if they themselves do the operation
• if they take frozen sections with a pathologist standing by
• if they've been innovative in their practice
• if they have plans for penile rehab and continence recovery
• if they plan to monitor your recovery using validated questionnaires
• if they seem like they will remain accessible
As for the weight - yes, it can make a difference in the success of your treatment. Here's what one study concluded:
Yamoah et al. said...
BMI of greater than 29kg/m2 is an independent predictor of adverse RP-risk requiring additional RT, particularly in patients with intermediate risk disease. This select group of patients may be best treated with definitive radiation therapy to prevent the additional toxicity from adjuvant or salvage RT following RP. We propose including BMI in clinical decision-making for appropriate treatment recommendation for patients with intermediate risk prostate cancer.

benefit for radiation. It acts as a buffer between the prostate and other organs - kind of like the spacer gel we were just discussing in another thread.
As for the side effects one can expect from surgery, Mike Scott came up with a pretty comprehensive list:

His rosy picture of post-RP erectile function is not realistic. In most studies, only 21%-27% of men who were previously potent return to the same baseline sexual function after nerve-sparing RP:

An analysis of sexual function outcomes following laparoscopic radical prostatectomy.I'm not saying this to scare you away from it - but I think it's important to have realistic expectations. Too many men are unpleasantly surprised not only by erectile dysfunction, but by penile shrinkage, climacturia, etc. Knowing this upfront will, I hope motivate you to engage in penile rehab early:
