To assess the reproducibility of bladder voiding efficiency (BVE, Void%) between free flow (FF) and intubated flow (IF) and to correlate BVE measurements with urinary incontinence (UI) complaints and urodynamic (UDS) findings in women.
UDS recordings of women referred for LUTD evaluation to our UDS center were reviewed. Each file included FF at arrival, filling cystometry, and IF. Post-void residual volumes (PVR) were measured by catheterization after FF and IF. Women unable to void during the study or who expelled the catheter during IF, as well as studies with voided volume < 100 ml were excluded. Data was sub-analyzed according to 3 age categories, and UI complaints and UDS findings.
Over the past 3 years, 237 UDS studies for FF and IF met all criteria. There was significant difference between voided volumes (232 . 335 ml) and PVR (24 . 71 ml) respectively ( < 0.0001). For the whole population, BVE IF (79.8 ± 28.6) was significantly lower than BVE FF (90.7 ± 15.9) ( < 0.0001). A significant decrease of BVE during IF was only noted for UI. BVE IF was significantly different in women in the peri-menopause and older groups. PVR IF increased with age and was significantly higher than PVR FF for women older than 45 years ( < 0.0001).
BVE measurement in women has a role, but is most reliable from a FF. BVE is influenced by age and urinary incontinence complaints as well as UDS findings.
评估自由流（FF）和插管流（IF）之间膀胱排尿效率（BVE，排尿率）的可重复性，并将BVE测量结果与女性尿失禁（UI）主诉及尿动力学（UDS）检查结果进行关联分析。
回顾了因下尿路疾病（LUTD）评估而转诊至我们尿动力学中心的女性患者的尿动力学记录。每个文件包括到达时的FF、膀胱容量测定和IF。FF和IF后通过导尿测量残余尿量（PVR）。排除研究期间无法排尿或在IF期间拔出导管的女性，以及排尿量<100 ml的研究。根据3个年龄类别、UI主诉和UDS检查结果对数据进行亚分析。
在过去3年中，237例FF和IF的尿动力学研究符合所有标准。排尿量（232.335 ml）和PVR（24.71 ml）之间分别存在显著差异（<0.0001）。对于总体人群，IF时的BVE（79.8±28.6）显著低于FF时的BVE（90.7±15.9）（<0.0001）。仅在UI患者中观察到IF期间BVE显著下降。围绝经期和老年女性组的IF时BVE存在显著差异。PVR IF随年龄增加，45岁以上女性的PVR IF显著高于PVR FF（<0.0001）。
女性BVE测量有一定作用，但FF时最为可靠。BVE受年龄、尿失禁主诉以及UDS检查结果的影响。
