I agree. It is nice to support your local surgeon. But, if it is at all possible, I would seek the MOST experienced surgeon you can find, that is covered by your insurance. If Ash Tewari is a possibility I'd get right on it, starting on monday.
Do not worry about hurting the feelings of your local surgeon, or your urologist. If they are true professionals, they'll understand and be supportive. If they are not supportive and understanding they would not be on my short list for my treatment team.
Good luck on your journey.
If the local dr. with the 50 da vincis is the one, you will still probably do fine.
