Roger Sur, MD, is a board-certified urologist and founder/director of the Comprehensive Kidney Stone Center at UC San Diego Health that focuses on surgical treatment, medical prevention and research into causes of kidney stones. He specializes in percutaneous nephrolithotomy using the latest minimally invasive techniques.

As a professor in the Department of Urology, Dr. Sur instructs medical students, residents and fellows at UC San Diego School of Medicine, where is also program director of the joint UC San Diego-Kaiser Endourology fellowship. He also works as a urologist at VA San Diego Healthcare System and as an associate professor of surgery at the Uniformed Services University of the Health Sciences, a military medical school.

Dr. Sur's research interests include antimicrobial use in kidney stone surgery, use of minimally invasive surgical techniques and minimizing use of radiation during surgery with the use of ultrasound imaging. His work has appeared in medical and research publications, including Journal of Urology and Journal of Endourology. He has published numerous manuscripts and book chapters.

Before joining UC San Diego Health in 2009, Dr. Sur served 21 years as a naval physician in numerous overseas deployments and retired with the rank of captain in U.S Navy Medical Corps. He completed an endourology fellowship at Duke University (North Carolina) and a residency in urology at Naval Medical Center San Diego. Dr. Sur earned his medical degree at Eastern Virginia Medical School.

Dr. Sur is a member of the American Urological Association and Endourology Society.

In 1997, during Dr. Sur’s residency at Naval Medical Center San Diego, he had a vision of creating a dedicated kidney stone center in San Diego. He wanted something that would be comprehensive — covering complex and routine surgery, training young surgeons, and performing research into the disease. More than 20 years later, he helps to deliver the best in kidney stone surgery and train both residents and fellows who will serve the same care to patients at UC San Diego.
