good sites to find statistics on specific surgeons? was No Subject

Does anyone know of any good sites to find statistics on specific surgeons? All the Doctor Rating Sites I've been to pretty much suck. How does one find impartial data, rankings, etc or is it even possible? I'm perfectly comfortable asking any doc what his (and his institution's) statistics are for post-surgery incontinence, ET, recurrence, etc, but that's for the doctors that I'm getting in to See, right? If I called 50 Urological Oncologist and asked their assistant these questions, do you think I'd get an answer? Does it boil down to word of mouth, anecdotal information, etc and personal visits??

That said, our Robotic option would be a surgeon named Tim Wilson, at the City of Hope in the Los Angeles area . I'm told he's done over 1,000 but we don't meet w/him until 5/25/10.
Our open option is with Mark Litwin at UCLA Med. Center. Met with him and thought he was great..."at the top of his game" (his words - but we totally believe him and I like the idea of a somewhat cocky surgeon...he is confident and instills confidence. He says 1 night in the hospital and 1 week on the cath but that we'll have ED and Incontinence (incontinence likely to be short-lived). He does his own follow up (prefers to be the one to remove the cath, for instance) which my husband thinks bodes well and I pretty much think is a moot point.

These two guys were recommended by other physicians known by us or by knowledgable friends.
