I don't have any personal experience, but the method, as you described it, has been pretty well accepted and widely used for some time; and apparently it seldom has adverse consequences.

Your doctor is, of course, the one best qualified to make recommendations since (one hopes) (s)he knows your particular situation and condition. If it's a real concern, a second opinion from another qualified doctor would be a good idea. And/or if your current doctor intends to have someone else actually do the procedure, a talk with the one who's going to do it before you agree shouldn't be considered an unreasonable request.
