- The study evaluated a multicomponent behavioral intervention to increase fluid intake for preventing urinary stone recurrence.
- Participants were randomized into intervention (fluid prescription, financial incentives, health coaching) and control (guideline-based care) groups.
- Primary outcome: No significant difference in symptomatic stone recurrence between intervention (19%) and control (20%) groups over 2 years.
- Secondary outcomes: Intervention group showed higher 24-hour urine volume but more urinary storage symptoms (frequency, urgency, nocturia) at 6 and 12 months.
- No difference in stone growth or new stone formation between groups; no severe hyponatremia cases reported.
- Conclusion: The intervention increased urine volume but did not reduce stone recurrence compared to standard care.
