Hydration Alone Falls Short in Stopping Kidney Stone Recurrence
A large Lancet-published trial found that a behavioral hydration program—using Bluetooth water bottles, personalized fluid goals, financial incentives, reminders, and health coaching—increased fluid intake and urine output but did not reduce symptomatic kidney stone recurrence over two years. Enrolling 1,658 participants across six U.S. centers, the study highlights the challenge of maintaining very high hydration and suggests that prevention will require more personalized hydration targets, strategies to overcome real‑world barriers, and possibly additional therapies to keep minerals dissolved in urine.
