Hydration Intervention Did Not Reduce Stone Recurrence

A behavioral strategy modestly increased urine volume but did not lower symptomatic events over 2 years.

1

A behavioral intervention to increase fluid intake did not significantly reduce kidney stone recurrence compared to usual care in a clinical trial.
2

The trial involved 1,658 patients with urinary stone disease, who were assigned to either the intervention or control group.
3

Both groups received guideline-based care and a smart water bottle, but only the intervention group received additional support.
4

Urine volume increased in both groups, but the intervention did not lead to fewer symptomatic stone events over 24 months.
5

Secondary outcomes related to stone growth and new stone formation were similar between the intervention and control groups.
