"By one year after surgery, 93 percent of the men reported that they were dry -- that during the previous four weeks, they had not needed a pad or adult diaper to control urinary leakage. When the men were asked to say how much their urinary continence bothered them, 98 percent said they had either a small bother, or none at all. In terms of potency, at 18 months after surgery, 86 percent of the men were able to have intercourse. When asked about
difficulty with erections, 84 percent of the men said they had either a small bother, or none at all. Looking at the potency rates by age, at 18 months after surgery, 100 percent of men in their thirties were potent; 88 percent of men in their forties, 90 percent of men in their fifties, and 75 percent of men in their sixties were potent.
Urologist-in-chief Patrick C. Walsh, M.D., who led the study, was not surprised at the success with urinary continence; he has reported the same results for many years. "In the long run," he says, "only about
2 percent of patients have significant long-term problems with urinary control" (defined as needing to change a pad more than once a day). "We are currently trying to eliminate that 2 percent." (See "Perfecting the Radical Prostatectomy.") The men's results with sexual potency, however, "are better than we've ever reported," says Walsh. They are also the highest potency rates reported at any academic medical center. "
