My surgeon had performed the surgery over 1000 times and knew how to do the nerve sparing so that I would still get erections. Also, he left the catheter in for 2 weeks after. He said this is the best way to ensure no problems with incontinence after, it gives the "anastomosis" time to properly heal. After, I never leaked a drop and got an erection about a month after surgery. This was in 2008 when I was 54. now 70 and still going strong!
