androgen receptors and the prostate and, in 1979, published his technique for the management of the dorsal vein complex during radical retropubic prostatectomy. Dr. Walsh's technique illustrated that patients who underwent radical retropubic prostatectomy did not always become impotent or incontinent. Later that year at a meeting of the Genito-Urinary Surgeons, Dr. Walsh met Pieter Doncker, MD, the outgoing chair of urology in Leiden, Netherlands. They maintained contact and, in 1981, Dr. Walsh attended a conference in Leiden and worked with Dr. Doncker to dissect the pelvic nerves of an infant. They spent three hours tracing the nerves to the corpora cavernosa and observed that they were located outside the capsule and fascia of the prostate, and showed that the nerves traveled in a cluster of arteries and veins of the prostate. On April 26, 1982, Walsh performed the first purposeful nerve-sparing radical prostatectomy on a 52-year old patient who reported seven months later that he was potent.
In 1980, only seven percent of men with localized prostate cancer underwent radical prostatectomy for fear of incontinence and loss of
