App and bottle combo aims to flush away kidney stones
NCT ID NCT06269783
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tested a system called sipIT that uses a smart water bottle and phone app to track fluid intake and send reminders. The goal was to see if it helps kidney stone patients form a habit of drinking more fluids. 172 adults with a recent kidney stone diagnosis used the system for 3 months. The study focused on understanding how behavior change works, not on directly treating stones.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- sipIT fluid tracking system with reminders
- What this could lead to
- If successful, this could point toward a simple, app-based way to help kidney stone patients drink more fluids and reduce stone risk.
- What could go wrong
- This is a small, completed study focused on understanding behavior change, not on proving that the intervention prevents stones. Results may not apply to all patients.
