Aim To validate a novel digital health monitoring system to measure the volume of voided urine. Methods Micturition volume was calculated using our novel digital self‐health monitoring system of urine excretion (s‐HMSU) in 18 participants (16 women and 2 men; average age, 40.8 years), without a history of voiding symptoms. Participants completed a self‐reported questionnaire regarding their medical history and water intake during the period of observation, as well as the Core Lower Urinary Tract Symptom Score (CLSS) questionnaire. To assess the reliability of the voided volumes measured using the s‐HMSU, the intraclass correlation coefficient (ICC) was calculated between the volume and the change in body weight before and after micturition. Results The CLSS questionnaire confirmed the absence of urinary system diseases in all participants. The medical history was also negative with the exception of hypertension in one participant. The ICC (1,1) between the measured volume of urine excretion using the s‐HMSU and the change in body weight was 0.972 (95% confidence interval, 0.957‐0.982). Conclusions The s‐HMSU system provides a reliable measure of voiding volume and is appropriate for home use. It has the potential to facilitate large‐scale clinical research to examine the relationship between medical diseases and voiding dysfunction.
