This paper describes a novel wearable personal uroflowmeter and its use to log urine leakage episodes in women. Consisting of a miniature flow rate sensor attached under the urethral meatus, it recorded both urine flow rate and volume during activities of daily living. The sensor communicated with a determining unit incorporating a microcontroller and an inertial measurement unit worn at the waist, facilitating the post-hoc determination of which activities and changes in pose caused leakage. Six women participated in a feasibility study performed in a clinical setting. The results indicate that the uroflowmeter was 97.5% accurate in assessing micturition flow compared to gold standard uroflowmetry and leakage measurements. The system also provides subject-specific information on the relationship between physical activity and urine leakage, thereby eliminating errors due to missing data and recall bias in bladder leakage diaries and circumventing the limitations of office-based uroflowmeters.
本文介绍了一种新型可穿戴式个人尿流计及其在记录女性漏尿事件中的应用。它由一个附着在尿道口下方的微型流速传感器组成，可在日常生活活动中记录尿流率和尿量。该传感器与一个包含微控制器和佩戴在腰部的惯性测量单元的测定单元通信，便于事后确定哪些活动和姿势变化导致了漏尿。六名女性参与了在临床环境中进行的可行性研究。结果表明，与金标准尿流测定法和漏尿测量相比，该尿流计在评估排尿流量方面的准确率为97.5%。该系统还提供了关于身体活动与尿漏之间关系的特定受试者信息，从而消除了膀胱漏尿日记中因数据缺失和回忆偏差导致的误差，并规避了基于办公室的尿流计的局限性。
