在老年男性中，良性前列腺综合征（BPS）是最常见的泌尿系统疾病。夜尿是BPS的主要症状之一，对生活质量有相当大的影响。对于BPS（包括夜尿症）的评估，国际前列腺症状评分被广泛使用，但调查问卷容易出现偏差。迄今为止，还没有可用于夜尿症的客观测量系统。在这项研究中，我们提出了一种不引人注目且不耻辱的设备，用于客观测量夜间排尿。在对 6 名被诊断为 BPS 且夜间排尿≥ 2 次的男性进行的初步研究中，我们表明该设备是准确的，在比较夜间排尿发生的平均次数时，平均误检率为 0.32 个事件，平均绝对偏差为 3.8%。在这项扩展研究中，另外记录了九名男性，并且还包括来自占用传感器的数据。初步研究结果得到证实，平均误检率为 0.33 个事件，平均绝对偏差为 9.1%。因此，该系统可用于客观测量夜间排尿，从而为治疗（例如药物疗效评估）提供基础。
Among elderly males, benign prostate syndrome (BPS) is the most common urinary disorder. Nocturia is one of the major symptoms of BPS and has a considerable influence on the quality of life. For assessment of BPS (including nocturia), the International Prostate Symptom Score is widely used, but questionnaires are prone to bias. To date, there is no objective measurement system available for nocturia. In this study, we present an unobtrusive and nonstigmatizing device for objective measurement of nighttime micturition. In a preliminary study of six males diagnosed with BPS and nighttime micturition ≥ 2×, we showed that the device is accurate, with an average misdetection rate of 0.32 events and a mean absolute deviation of 3.8% when comparing the average number of nighttime micturition occurrences. In this extended study, an additional nine males were recorded and data from an occupancy sensor were also included. The results of the preliminary study were confirmed with an average misdetection rate of 0.33 events and a mean absolute deviation of 9.1%. The system can, therefore, be used to objectively measure nighttime micturition and, thereby, provide the basis for treatment, e.g., medication efficacy assessment.
