I must say I found the following article in USA Today ( 4/1/09, by Liz Szabo) , bonechilling.  A British study confirms what I’ve said many times: that when it comes to performing minimally-invasive radical prostatectomy or laparoscopy (which includes robotically assisted surgery, *although that was not the subject of this study*),  NO amount of experience on the part of the surgeon is enough

And there is another very important point being made which I have NOT heard before:  That “open” surgeons  (those who perform the traditional radical retropubic prostatectomy) who later switch to laparascopic surgery produce (much) worse results than doctors who initially specialize in this area.

Here are some excerpts from the USA Today article (more comments at end):
