OBJECTIVE: To evaluate the usability and accuracy of a newly developed automated bladder diary (BD) device, the Uro-diary Checker (UDC), in comparison with a conventional handwritten BD.
METHODS: In this prospective, multi-institutional observational study, 40 patients with lower urinary tract symptoms (LUTS) were recruited between April 2023 and October 2024. Participants recorded their voiding patterns using a handwritten BD for 3 days and the UDC for the next 3 days. The UDC automatically recorded voiding time and volume when a urine cup was placed on the device, and the data were transferred via Bluetooth to a computer. The primary endpoint was usability, assessed using the System Usability Scale (SUS), a validated 10-item Likert-scale questionnaire.
RESULTS: Of the 40 enrolled patients, 31 successfully completed records using both methods and were included in the final analysis. The mean patient age was 72.6 ± 9.8 years; 24 were male and 7 were female. The SUS score was significantly higher for the UDC (72.9 ± 19.3) than for the BD (60.6 ± 19.5; P < .01), exceeding the benchmark score of 68 and indicating good usability. UDC-recorded urine volumes were highly consistent with BD measurements for both 24-hour urine volume (r = 0.86, P < .01) and average voided volume (r = 0.77, P < .01).
CONCLUSION: The UDC demonstrated significantly greater usability than the conventional BD while maintaining comparable accuracy for urine volume measurements, suggesting its potential to improve adherence and efficiency in LUTS evaluation.
