Maximum bladder volume could be a simple surrogate measure to screen for detrusor overactivity (DO) which manifests with a frequency and small volume voids. Urodynamic traces from 577 women were reviewed. Maximum bladder volume was obtained from bladder diary. The urodynamic traces were reviewed for data and were categorised as normal, urodynamic stress incontinence, mixed incontinence and DO. The urodynamic data and maximum voided volume were compared between different categories and Receiver operating characteristic (ROC) curves were constructed. The median value for maximum-voided volume for women with DO was not significantly different from the other categories, whereas significant differences were found for the median values for urodynamic variables. ROC curves demonstrated extremely poor sensitivity and specificity for recorded maximum bladder volume and for urodynamic variables. The maximum-voided volume recorded on a three-day bladder diary is not discriminatory as a screening test for DO.
最大膀胱容量可能是一种简单的替代指标，用于筛查表现为尿频和小尿量排尿的逼尿肌过度活动（DO）。回顾了577名女性的尿动力学记录。最大膀胱容量来自膀胱日记。对尿动力学记录进行数据审查，并分类为正常、尿动力学压力性尿失禁、混合性尿失禁和DO。比较不同类别之间的尿动力学数据和最大排尿量，并构建受试者工作特征（ROC）曲线。DO女性的最大排尿量中位数与其他类别无显著差异，而尿动力学变量的中位数存在显著差异。ROC曲线显示，记录的最大膀胱容量和尿动力学变量的敏感性和特异性极低。三天膀胱日记记录的最大排尿量作为DO的筛查试验并无鉴别意义。
