    ‘Smart’ water bottle may help with stone prevention

    Bottle’s accuracy in measuring consumption also could aid clinical research


    Bottle’s measurements ‘very accurate’

    The authors found that the bottles underestimated actual liquid consumption by a mean of 0.5 oz (95% CI: 1.9, 0.9); the mean 24-hour measurement was 57.2 oz (21-96).

    "We found out that it was very accurate," Dr. Borofsky said. The bottles’ high reliability raises the prospect that the bottles could become more than a hydration aid. They could also serve as a research tool since they could provide more reliable details about the liquid intake of subjects than questionnaires, he said.

    What's next?

    "We're currently working on a multicenter study and will be enrolling patients shortly. We'll try to implement the water bottle for patients with a recognized fluid deficiency who are forming kidney stones. We'll see if the smart water bottle increases urine output compared to standard of care,” Dr. Borofsky said.

    As for now, Dr. Borofsky says he's been using the smart water bottle himself.

    "I'm certain that I'm not meeting the recommended hydration goals. It’s encouraged me to be more aware of how much I'm drinking and influenced me to be a little more proactive about staying hydrated,” he said.

    Hidrate Inc. provided free smart water bottles for the study.
