To compare the accuracy of the 3D portable ultrasound with catheterization in the assessment of postvoid residual (PVR) urine volume among women in the urogynaecology clinic.
A prospective study was performed, assessing 101 women. After the patient voided four ultrasound (US) assessments were carried out using the BladderScan BVI 3000; the patient was then catheterized. The reproducibility of the US measurements and the difference between the two methods were assessed using Bland and Altman plots. The strength of the relationship was measured by a simple Pearson correlation coefficient.
The results showed that 3D scanner measurements were highly reproducible and were also found to correlate significantly with catheterized volume (r=0.79, 95% CI 0.70-0.85, P<0.001). The mean difference between the two methods was 12.9 mL (95% CI 5.5-20.2 mL, P<0.001).
In determining PVR volumes, the portable ultrasound BladderScan BVI 3000 is an accurate alternative to bladder catheterization.
比较三维便携式超声与导尿术在评估妇科泌尿门诊女性患者残余尿量（PVR）方面的准确性。
进行了一项前瞻性研究，评估了101名女性。患者排尿后，使用膀胱扫描仪BVI 3000进行了四次超声（US）评估；然后对患者进行导尿。使用Bland和Altman图评估超声测量的可重复性以及两种方法之间的差异。通过简单的Pearson相关系数测量关系强度。
结果表明，三维扫描仪测量具有高度可重复性，并且还发现与导尿量显著相关（r = 0.79，95%CI 0.70 - 0.85，P < 0.001）。两种方法之间的平均差异为12.9 mL（95%CI 5.5 - 20.2 mL，P < 0.001）。
在确定残余尿量时，便携式超声膀胱扫描仪BVI 3000是膀胱导尿术的一种准确替代方法。
