Post-void residual urine (PVR) is a key variable in the assessment of the emptying function of the lower urinary tract and is often used as an outcome measure after treatment. Increased PVR can lead to further investigation and treatment, or cancellation of planned incontinence surgery. In a prospective study, we aimed to assess the repeatability of the finding of PVR ≥ 100 ml in urogynaecologic patients.
Of 396 women with urogynaecologic complaints visiting our outpatient clinic, 297 had PVR measured after a micturition in full privacy preceded by normal desire to void. Women with PVR ≥ 100 ml were offered a second and eventually a third PVR measurement after a subsequent micturition. A Verathon Bladder Scanner BV 9400 was used to measure PVR immediately after micturition.
The prevalence of PVR ≥ 100 was 14%, which declined to 1.3% on repeated measurements. Voided volumes did not vary between voids.
One PVR measurement ≥ 100 ml is unreliable and needs repetition to confirm consistency.
排尿后残余尿量（PVR）是评估下尿路排空功能的关键变量，常用于治疗后的疗效评估。PVR增加可能导致进一步检查和治疗，或取消计划中的尿失禁手术。在一项前瞻性研究中，我们旨在评估在泌尿妇科患者中发现PVR≥100ml这一结果的可重复性。
在我们门诊就诊的396例有泌尿妇科症状的女性中，297例在有正常排尿欲望且完全私密的情况下排尿后测量了PVR。PVR≥100ml的女性在随后排尿后接受了第二次、最终第三次PVR测量。使用Verathon膀胱扫描仪BV 9400在排尿后立即测量PVR。
PVR≥100的患病率为14%，重复测量后降至1.3%。每次排尿的尿量无变化。
单次PVR测量≥100ml不可靠，需要重复测量以确认一致性。
