surel nerve graft

I am 46 and I was diagnosed in Aug. 9, 2002 with a 15.9 my gleason was a 7 at pre op and an 8 post op it was just breaking through the gland when i had the RP. so far my p.s.a. has remained 0.01 yea!.
I went to the University of MIchigan hospital at the time of my surgery they harvested a nerve from from my ankle and grafted it in place of one they could not save. I was told this is a new procedure I was the 51st patient to receive this treatment.
and there are only two other hospitaols doing it now one in new york and one in texas. would appreciate any comments from others who have had this treatment
