Dr. John Kaspar

My clinical interests include the minimally invasive management of urinary tract stones, including shock wave lithotripsy, percutaneous, and ureteroscopic stone removal. I completed my training at the University of North Carolina in 1983 and was an American Urological Association Scholar (1983-1985) in the Division of Mineral Metabolism at the University of Texas Southwestern Medical Center, Dallas. In 1993, I returned to North Carolina as professor of urological surgery and director of the Duke Comprehensive Kidney Stone Center.

I am focused on the surgical and medical management of kidney stones. I do a large volume of surgeries for kidney stones, however what gives me the most satisfaction in my practice is helping my patients prevent kidney stone recurrence. I work closely with my patients to determine the specific causes for their kidney stones. We review this information and then decide on a preventative plan, which often includes dietary changes and even medications. I find it extremely rewarding to help my patients prevent kidney stones, as many of them are surprised that it is possible to prevent them.
