摘要目的:研究全国各地老年女性人群的尿流率数据并分析尿流率参考值范围。方法:本研究自2020年7月至2022年6月入组333例受试者，研究实施过程分为两步：第一步，受试者填写电子化问卷，问卷包括受试者基本信息，尿失禁简表，膀胱过度活动症症状评分表；第二步，工作人员介绍移动尿流率仪的使用方法，分发仪器及材料。尿流率数据经手机自动上传到云端数据库，2名以上的尿控亚专科的医生进行尿流率合格筛选后进行统计学分析。结果:333例受试者入组，移动尿流率仪采集合格尿流率记录1 375条。受试者年龄为60～84岁，平均69岁，尿流率参考范围分别为：尿流时间为24.8～26.2 s，平均尿流率为12.2～12.9 ml/s，最大尿流率22.2～23.4 ml/s，达峰时间为8.5～9.7 s；随着年龄增长，老年女性的最大尿流率和平均尿流率呈下降趋势(Pearson相关系数：－0.1， P<0.001)。 结论:老年女性的排尿速率随年龄增加而降低，80岁以上老年女性受试者的平均尿流率较其他年龄组低，本研究为中国老年女性的尿流率检查提供正常参考范围。

abstractsObjective:To collect data on urinary flow rate in the elderly female population across the country and to analyze the range of reference values.Methods:This study enrolled 333 subjects from July 2020 to June 2022.The study implementation process was divided into two steps.In the first step, subjects completed an electronic questionnaire, which included basic information about the subject, a short form for urinary incontinence, and a scoring form for the symptoms of overactive bladder syndrome.In the second step, the staff introduced the use of a mobile uroflowmetric device and distributed the instrument and materials.Uroflow rate data were automatically uploaded to a cloud database via the mobile phone.Subsequently, two or more physicians specializing in urinary control performed Uroflow rate-qualifying screenings and conducted statistical analyses.Results:A total of 333 subjects were enrolled in the study, and the researchers collected 1375 qualified urine flow rate records using a mobile urine flow rate instrument.The age of the subjects ranged from 60 to 84 years, with a mean age of 69 years.The reference ranges for urinary flow rate were found to be 24.8-26.2 s, with a mean urinary flow rate of 12.2-12.9 ml/s, a maximum urinary flow rate of 22.2-23.4 ml/s, and a time to peak of 8.5-9.7 s. The study observed a tendency for both maximal and mean urinary flow rates to decrease in older women as their age increased(Pearson correlation coefficient: -0.1, P<0.001). Conclusions:The uroflow rate of older women decreases with aging.Specifically, the average uroflow rate of women over 80 years old is lower than that of other age groups.This study aims to establish normal uroflow parameters for uroflowmetry in healthy older women in China.
