I wholeheartedly agree with Yooper that with one core positive, Gleason 6, you should think very carefully before accepting the current adivce you're being given.
I'm not a doctor, and I don't have all the information your uro has, but I would want a much better explanation of (1) why surgery is required at this time, and (2) why that nerve bundle can't be spared. Maybe it's because of the location from which the positive core was taken, but the number of biopsies doesn't seem like a logical explanation to me. Active Surveillance might be a very good option for you.
In a DaVinci surgery, you will certainly be intubated and thoroughly anesthetized. The surgery may take as long as 3 or 4 hours.
This is major, life altering surgery, and I think you need better information and better explanations before agreeing to this. A second or even third opinion would be well worth your time, and not all of them from a uro/surgeon. Brachytherapy should be investigated, or external beam radiation.
If your uro didn't thoroughly discuss with you the possibility of Active Surveillance, if he didn't thoroughly discuss options other than surgery, if he didn't thoroughly explain why it would be necessary to remove that nerve bundle and what the implications of that would be for you, if he didn't talk to you about the differences between your Gleason 6 diagnosis and a diagnosis of Gleason 7, 8, or 9....if he didn't do all those things I would drop him and find a new urologist.
Good luck in your decision-making process. I'm sure other guys will add their thoughts.
