To assess the validity of a commercially available bladder volume scanner in the puerperium.
A prospective blinded comparison of bladder volume measurement after vaginal delivery using the BladderScan bladder volume instrument (BVI) 3000 and Foley catheter; comparison using the intraclass correlation coefficient.
The mean difference between the two measurements was a 130-mL over-measurement by the bladder scanner (range: -156 mL to +422 mL). The intraclass correlation coefficient was 0.23 (95% confidence interval 0.00, 0.59).
The BladderScan BVI 3000 is not an accurate instrument to assess bladder volume the day after vaginal delivery. Some of the discrepancy might relate to use of the Foley catheter as the reference standard. Further comparison between the BladderScan and a short female catheter or real time ultrasound is indicated.
评估一种市售膀胱容积扫描仪在产褥期的有效性。
采用前瞻性双盲比较法，在阴道分娩后使用膀胱扫描膀胱容积仪（BVI）3000和Foley导尿管测量膀胱容积；使用组内相关系数进行比较。
两种测量方法的平均差异为膀胱扫描仪测量值高估130毫升（范围：-156毫升至+422毫升）。组内相关系数为0.23（95%置信区间0.00，0.59）。
膀胱扫描BVI 3000不是评估阴道分娩后次日膀胱容积的准确仪器。部分差异可能与将Foley导尿管用作参考标准有关。建议对膀胱扫描与短女性导尿管或实时超声进行进一步比较。
