- Kidney stones affects nearly 1 in 11 individuals at some point in their lives, and for many the experience repeats itself. It is desirable to initiate a medical prophylactic program to reduce the likelihood of recurrent kidney stones in high risk individuals. A simple screening evaluation can identify those individuals likely to experience recurrent kidney stones who would benefit from more extensive testing and initiation of preventative measures. In this podcast Margaret S. Pearle, M.D., Ph.D., Professor and Vice Chair of the Department of Urology at UT Southwestern Medical Center, describes the components of a screening evaluation as well as more detailed metabolic testing. Based on this evaluation, recommendations for stone prevention in the form of dietary modification and pharmacotherapy are offered. Finally, the importance of careful radiographic and biochemical follow-up of patients on medical therapy is underscored and specified.
