As Tud and 142 said, what you are asking for is walking a fine line. With that said, here is a link to a site, that allows you to search for surgeons by
location, name, or hospital, and will give you some information, most notably, rate of complications. There's other stuff we would want to know, like % of positive margins, % ED, % INCONTINENCE, ETC. That data is not available, but i would certainly want to know a surgeons rate of complications.
In the dropdown box on the left, are the various common procedures they rate surgeons for, and one of them you can choose is Prostate Removal...
