I was going to have Di Vinci but decided to have open based on a study I read. It indicated that there had been a 3 fold increase of the need for radiation and hormone treatment after robotic surgery. Keep in mind though that the study also said that those results were less when surgery was done by high volume doctors. Being able to actually get your hands on the organ to examine it during surgery I felt was very important. With my open surgey there was no need for blood and my recovery was the same as robotic procedure. Yes, there is a bigger scar but that was the least of my concerns. Keep reading, it will come to you what is best. Try to have a uro with at least 500 surgerys. Mine had done 1,200.
