10 Jun Kidney Stone Smart Water Bottle Study
The Urinary Stone Disease Research Network (USDRN) is conducting a kidney stone prevention trial entitled Prevention of Urinary Stones with Hydration (PUSH) and is funded by the National Institutes of Health (NIH).
PUSH is a 2-year randomized controlled trial assessing a program of behavioral interventions to increase fluid intake and adherence in order to decrease kidney stones. Participants in the intervention arm will receive an individualized “fluid prescription”, incentives for meeting daily fluid goals and coaching to overcome fluid intake barriers. Control arm participants will undergo usual stone prevention care, be informed about the goal urine output recommended by the AUA, and also receive a smart water bottle. The only in-person visits for PUSH are at the beginning and end of study for a low dose CT or ultrasound. All other contacts are remote including 24-hour urine home collections done at several points throughout the follow-up period.
In 2020, we are now enrolling out of the area participants with a study modification that allows for complete remote enrollment without needing to come to the study site for any visits.
