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 named as one of America’s Best Doctors. Following his 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. Dr. Clayman spent 17 years at Washington University School of Medicine in St. Louis, rising to the positions of Professor of Urology and Radiology, Director of the Midwest Stone Institute, and Co-director of the Division of Minimally Invasive Surgery. In January 2002, he was appointed chair of the newly formed Department of Urology at UCI Medical Center. Dr. Clayman and his associates performed the world’s first laparoscopic removal of a kidney for benign disease and for cancer, as well as the first laparoscopic removal of a kidney and ureter to treat cancer. He helped develop a balloon catheter to treat obstruction of the ureter and performed pioneering work on percutaneous and endoscopic therapy for ureteral and kidney stones. Dr. Clayman established the first fellowship program in minimally invasive urology, and trainees of his program now occupy academic positions at universities throughout the United States, Canada, and Israel. Dr. Clayman is the author of textbooks on laparoscopic and percutaneous urologic surgery, and has published more than 480 peer-reviewed papers and book chapters. He is co-founder and coeditor of the Journal of Endourology. He has 16, minimally invasive surgical instrumentation patents to his name. He is a member of the American Board of Urology, a position he will hold through 2011. He is a member of the American Association of Genitourinary Surgeons, the Clinical Society, and the American Surgical Association.
Dr. Clayman’s patient care, teaching, and research efforts are focused on developing and perfecting all aspects of less invasive surgery in which incisions are either reduced in size or eliminated all together. In order to accomplish this goal, he and his team continue to explore a broad range of minimally invasive and noninvasive surgical techniques to bring up-to-the-moment technology into the operating room. He was named interim Dean of the School of Medicine in 2009 and was appointed to that position full time in 2010; accordingly his clinical practice and his research activities have been significantly curtailed. He currently has limited his practice to urolithiasis and image guided needle ablative cryotherapy of renal cancer.
