Objective:

To evaluate the effectiveness of a multicomponent behavioral intervention aimed at increasing fluid intake specifically to reduce symptomatic kidney stone recurrence.

Approach:

Key Findings:

• Symptomatic stone events occurred in 19% of the intervention group vs 20% of the control group, with no significant difference.
• Urine volume increased in both groups, with the intervention group showing a greater increase (600 mL/day vs 360 mL/day), although the difference diminished over time.
• Secondary outcomes related to stone growth and new stone formation were similar between groups.
• Urinary storage symptoms were more common in the intervention group at 6 and 12 months.

Interpretation:

Despite achieving higher urine volumes, the behavioral intervention did not lead to a reduction in symptomatic kidney stone recurrence over 2 years, indicating no correlation between increased urine volume and reduced recurrence.

Limitations:

• Participants were recruited from tertiary care centers, which may limit generalizability to broader populations.
• Increased urine volume in the control group may have reduced detectable differences between groups.
• Additional fluid intake not captured by the smart water bottle was not measured.

Conclusion:

The increase in urine volume from the behavioral intervention did not correlate with a decrease in recurrent symptomatic stone events over the 2-year follow-up.
