Dr. Walsh is best known for his 30 years as the Professor and Director of the Brady Urological Institute (1974 - 2004) and for his pioneering work in the development of “the anatomic approach to radical prostatectomy”, which involves nerve-sparing techniques that have reduced the probability of impotence and incontinence.  He has also made major contributions to the basic understanding of benign and malignant neoplasms of the prostate.  Along with co-workers, he was the first to describe the 5 alpha-reductase enzyme deficiency, to develop an experimental technique for the induction of benign prostatic hyperplasia, to demonstrate the influence of reversible androgen deprivation on BPH, and to characterize hereditary prostatic cancer.  He is on the editorial board of the New England Journal of Medicine and is a member of the Institute of Medicine of the National Academy of Sciences.  For 25 years he was the editor-in-chief of Campbell’s Textbook of Urology, which has been renamed Campbell Walsh in his honor.  In 1996, Dr. Walsh received the Charles F. Kettering Medal from the General Motors Cancer Research Foundation for “the most outstanding recent contributions to the diagnosis and treatment of cancer.” Dr. Walsh was honored as the 2007 National Physician of the Year for Clinical Excellence by America's Top Doctors®, and was the co-recipient of the 2007 King Faisal International Prize in Medicine.  Together with Janet F. Worthington, he authored the best-selling books for lay people The Prostate: A Guide for Men and the Women Who Love Them, which is published by Johns Hopkins University Press (1995) and Warner Books (1997) and more recently, Dr. Patrick Walsh’s Guide to Surviving Prostate Cancer, Warner Books (2001 and 2007).  Dr. Walsh served as the president of both the American Association of Genitourinary Surgeons and the Clinical Society of Genitourinary Surgeons
