Dave see my prior posts on this decision. I had exactly the same numbers as you and after agonizing review, chose DaVinci prostatectomy. I do not regret it. Any time you can cure cancer with surgery, you should do it. If you have been reading the recent posts on this site about the side effects of Lupron, radiation etc, you will know the situation. There are downsides from surgery but they are manageable. ED is certain but can be boosted with drugs; there is some leakage on coughing and I have some low level pain in the urethra (rare). But I am now 4 years post surgery with a PSA of zero and retain a healthy libido and function. One thing you should do is to have the Prolaris test done to determine the degree of aggressiveness of your cancer. Best of luck.
