本研究的目的是评估一组接受临床UDS手术的患者的超声膀胱振动测量（UBV）和尿动力学研究（UDS）测量结果之间的相关性。对70例神经源性膀胱患者（男性56例，女性14例）同时进行UBV和UDS。膀胱壁的力学性能测量UBV在不同的充盈量与记录逼尿肌压力（Pdet）值相关。计算相关值的平均值、中位数和标准差，并检验这些观察结果的显著性。UBV测量的膀胱壁力学特性（群速度平方和弹性）与不同容积下测量的Pdet具有高度相关性（中位数相关性分别为0.73，CI：0.64-0.80和0.72，CI：0.56-0.82）。群速度平方和弹性与Pdet的相关性均大于0.5。本研究的结果表明，UBV可以密切监测一组接受UDS的患者在不同体积下膀胱壁力学性能的变化。UBV参数和逼尿肌压力测量值之间的高度相关性表明，UBV可以作为一种可靠的和具有成本效益的工具，以无创的方式评估膀胱壁的机械变化。
The objective of this study is to assess correlation between bladder wall mechanical properties obtained by ultrasound bladder vibrometry (UBV) and urodynamic study (UDS) measurements in a group of patients undergoing clinical UDS procedure. Concurrent UBV and UDS were performed on 70 patients with neurogenic bladders (56 male and 14 female). Bladder wall mechanical properties measured by UBV at different filling volumes were correlated with recorded detrusor pressure (Pdet) values. Mean, median and standard deviation of correlation values were calculated and the significance of these observations was tested. Bladder wall mechanical properties obtained by UBV as group velocity squared and elasticity showed high correlations with Pdet measured at different volumes (median correlation 0.73, CI: 0.64–0.80 and 0.72, CI: 0.56–0.82 respectively). The correlation of group velocity squared and elasticity with Pdet were both significantly higher than 0.5. The results of this study suggest that UBV can closely monitor changes in bladder wall mechanical properties at different volumes in a group of patients undergoing UDS. The high correlation between UBV parameters and detrusor pressure measurements suggests that UBV can be utilized as a reliable and cost-effective tool for assessment of the bladder wall mechanical changes in a noninvasive fashion.
