Patients will receive a smart water bottle, then instructed on bowel and bladder preparation for daily standard of care radiotherapy treatments for up to 10 weeks.

Patients will be given a smart water bottle and coached on its use. The device is a 24 oz non-bisphenol A acrylic water bottle with the ability to track water consumption from the bottle, alert its users via a smartphone-based notification system, as well as visually remind patients with a light-emitting diode in the device. Participants will be alerted to drink patient-specific volumes of room temperature water 45 minutes prior to daily standard of care radiotherapy.

Smart Water Bottle

The purpose of this study is to determine how to incorporate a smart water bottle to improve bladder filling for prostate cancer patients undergoing radiation therapy.

A Behavioral Health Intervention Using Digital Technology in Radiation Therapy for Prostate Cancer Patients

A Pilot Study Using a Digital Behavioral Intervention With a Smart Water Bottle to Improve Bladder Filling Compliance in Prostate Cancer Patients Undergoing Radiation Therapy

Proportion of participants will be reported as those who did not continue to use the intervention throughout the study.

Proportion of non-compliant participants via a patient-reported survey.

Non-compliance to study intervention will be assessed using a cone beam Computerized Tomography (CT) scan of participant's bladder volume

Patient reported scores based on Service User Technology Acceptability Questionnaire (SUTAQ) will measure patient's perception of the smart water bottle. SUTAQ has a total score ranging from 20-100 with the higher score indicating increased user acceptability and comfort with the device.

Proportion of screen-eligible participants who refused study participation
