I did a lot of research on all 3 types of surgery. My husband and I picked the robotic laproscopic prostatectomy.
The open surgery has a lot of draw backs: more blood loss, longer surgery time, cutting through all of the muscles and tissues, the surgeons vision is not as clear due to the blood in the surgery site, maginfication is not as good as the robotic (which is magnified by 16x), under anesthesia longer, recovery time is longer from the surgery, cathether is in longer, and also recovery time of continence and potency.
The laproscopic seemed better but it still had a few draw backs that I saw. First of all it does NOT move in the same direction as you would move your hand. For instance if you turn right, the instrument moves the opposite(to the left). Some surgeons don't do laproscopic surgery because they can't compensate doing things opposite of the way the instruments move. It does NOT magnify as much as the robotic. The surgeon has to sit in an awkward position during the whole surgery. It does NOT compensate for any surgeons temors or sudden movements.
The robotic laproscopic surgery has less blood loss, mimimal invasive (5 small holes), magnifies the surgical field by 16x, the panoramic camera that can turn 360, in color, 3 dimensional viewing, instruments are made to move in the direction the surgeon moves, the computer adjusts for and surgeon tremors or sudden movements, shorter recovery time, cathether is out sooner (5-7days), continence is returned sooner, nerve sparing surgery can be done with more precision in a bloodless field. Look at the City of Hope web site and it will tell you about the procedure in more details.

I also found out that it is VERY IMPORTANT to find a surgeon who does a LOT of whatever surgery you decide to have. Don't be afraid to ask the doctor how many he does a week or a month. Also ask what his outcomes of the surgery (continency & potency). All GOOD surgeons would give you the results. It should be up in the 90%. It might not be right away. The City of Hope gives a 50% of their patients are continent after one month, 75% after 3-6 months, and up in the 90's% after a year. The Dr. we saw did 8-10 of these surgeries a week. He has done over 1,000 of these procedures. He started by doing the open procedures, then the laproscopic and now the robotic laproscopic.
I know that a lot of the hospitals now do the laproscopic and the robotic laproscopic surgery. We talked to a lot of different men who had prostate surgery done. Good Luck.
