NCT ID NCT03244189

First seen Jun 26, 2026 · Last updated Jun 27, 2026 · Updated 1 time

Summary

This study tested whether a program to help people drink more water could prevent kidney stones from coming back. Over 1,600 adults and children who had a kidney stone in the past used a smart water bottle to track their intake, with some getting financial rewards for meeting their goals. The main goal was to see if this approach reduced the number of new stone events over two years.
