Most kidney stone treatment focuses on patients who have a kidney stone and are having excruciating pain. There has been little research into finding out how to prevent kidney stones. PUSH hopes to identify ways to change behavior so a patient is less likely to have another kidney stone, and help determine if drinking more water can really help prevent having another kidney stone.

Enrollment began in September 2017. For more information, contact one of our participating sites or check out the PUSH study listing on ClinicalTrials.gov.
