You can tell your surgeon that you wish him to do the entire procedure and, I believe, they are required then to do so. You don't want to sound like a b_tt, of course.
Mac's robotic surgeon (after visiting 3 medical centers - UCS, UCLA and City of Hope in southern california) was Tim Wilson at Hope. Mark Litwin (UCLA) would have been our choice had we gone open.
The surgery was a huge success - tomorrow we get our first post-surgery PSA. (and, of course, we're still nervous despite his excellent recovery in all areas.)
