My sister-in-law is a recovery room nurse in a hospital that just received a Da Vinci last year where one of the local Uros took a training course and is now preforming robotic prostate surgeries. Currently he has done about 75 surgeries, and does about one a week on average.
I asked my sister-in-law the same question as you, "what men would take a chance having surgery with a surgeon who has absolutely no experience doing this kind of delicate procedure, all knowing what the possible side effects can be ?" Well, she told me that the majority of the men that he does surgery on so far, they seem to be older, lower income, medicare guys that don't seem to have the financial options to be able to travel and interview surgeons. She also said that a lot of the men just seem to be not very educated in doing research about doctors, and they just accept everything the doctor says without question simply because he is a doctor, therefore he must be all knowing and know what he is talking about.
She did tell me about a couple of horror stories about this surgeon's learning experiences. During one of his first surgeries, he accidently put a cut in the intestine of some poor guy and they had to do a second surgery to repair the tear. In another surgery he screwed up sewing the ureatha to the bladder and had to operate again to repair that.
I guess everyone has to learn , but I am sure glad that I did my reaserch and I had the financial ability to pick the surgeon I wanted.
