5 Key Takeaways

• 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.
