先前的研究表明,超声膀胱振动测量(UBV)参数与尿动力学研究(UDS)测量结果密切相关。就像UDS一样,UBV可以在仰卧位和坐位进行。本研究的目的是比较UBV参数获得的两个不同的位置,使用统计方法。为此,我们招募了8名健康膀胱的志愿者。膀胱的弹性、群速度平方和厚度是感兴趣的UBV参数,并且记录每个志愿者在不同膀胱体积下的值。此处给出的结果表明,使用Bland Altman方法和参数q(比较每名志愿者在每个膀胱容积下的值),对两个位置进行的测量结果一致。在仰卧位和坐位记录的测量值的UBV参数也是可重复的。
Ultrasound Bladder Vibrometry (UBV) parameters have been shown by previous studies to strongly correlate with Urodynamic Studies (UDS) measurements. Just like UDS, UBV can be performed in supine and sitting positions. The objective of this study is to compare UBV parameters obtained for the two different positions using statistical methods. We recruited 8 volunteers with healthy bladders for this purpose. The elasticity, group velocity squared and thickness of the bladder were the UBV parameters of interest, and their values were recorded at different bladder volumes for each volunteer. The results presented here indicate that the measurements made for the two positions are in agreement using the Bland Altman method and a parameter q, which compares the values at each bladder volume for each volunteer. UBV parameters were also repeatable for measurements recorded in the supine and sitting positions.
