Dr. Clayman is world renowned for his expertise in minimally invasive surgery for kidney stone disease, kidney cancer and strictures of the ureter, and is listed among the Best Doctors in America® for Urology. He is a graduate of Grinnell College and the University of California, San Diego School of Medicine. Following general surgery and Urology training at the University of Minnesota, he spent two years at Southwestern Medical School in Dallas pursuing his interests in renal cancer research, kidney stone disease and minimally invasive Urology. Subsequently, Dr. Clayman spent 17 years at Washington University School of Medicine in St. Louis, rising to the rank of Professor of Urology and Radiology, Director of the Midwest Stone Institute and the inaugural Co-director of the Division of Minimally Invasive Surgery.
In 1990, Clayman and his associates performed the world's first laparoscopic removal of a kidney for a tumor, as well as the first laparoscopic removal of a kidney and ureter to treat cancer. They also developed a cutting balloon catheter to treat obstruction of the ureter and performed pioneering work on percutaneous and endoscopic therapy for ureteral and kidney stones. He established the nation's first fellowship program in minimally invasive urology in 1984; trainees of his program now occupy academic positions at universities throughout the United States, Brazil, Spain, Italy, Canada and Israel. Clayman is the author of textbooks on laparoscopic and percutaneous urologic surgery, and has published more than 400 peer-reviewed papers and book chapters.

In 2009, Dr. Clayman stepped down as Chair of Urology to become Dean of the School of Medicine. After a successful 5 year term as Dean, he elected to return to the Department of Urology as a Professor.
