I had a couple of stitches for continence not sure where they were put but doc said it has added 4 minutes to his op time, and patients have had much improved continence rates, he said procedure was reported at a major urological conference in early 2010 early 2009 ?, so don't know who started doing it first but my doc didn't ask me did I want it he said he now does it on all his patients and has seen vast improvements.
So if you are comming up for surgery ask your Uro about it the data is out there.
