The aim of the study was to assess the interobserver and intraobserver reliability of translabial 3D ultrasound imaging of the urethral sphincter in non-pregnant nulliparous asymptomatic women.
A study using a 3D translabial ultrasound on thirty-seven women was performed. Urethral sphincter parameters were measured by the same experienced clinician 2 weeks apart. Multiple axial cross-sectional areas at 1-mm distances were used to calculate urethral sphincter volumes. The same measurements were carried out by a second experienced clinician to assess the interobserver reliability.
We found an excellent intraobserver reliability (interclass correlation coefficient, ICC >0.8) and good interobserver reliability (ICC >0.6).
The described technique using multiple axial cross-sectional areas at set distances and a translabial approach is a reliable and accurate tool in the evaluation of the urethral sphincter. This should be used instead of mathematical formulas as the urethral sphincter is not a uniform geometrical sphere. The technique and values reported may help clinicians in the assessment of women with lower urinary tract disorders.
本研究的目的是评估非孕未育无症状女性经阴唇三维超声成像对尿道括约肌的观察者间和观察者内可靠性。
对37名女性进行经阴唇三维超声研究。由同一位经验丰富的临床医生在两周的间隔时间内测量尿道括约肌参数。使用间隔1毫米的多个轴向横截面积来计算尿道括约肌体积。由另一位经验丰富的临床医生进行相同测量以评估观察者间可靠性。
我们发现观察者内可靠性极佳（组内相关系数，ICC>0.8），观察者间可靠性良好（ICC>0.6）。
所描述的使用设定距离的多个轴向横截面积和经阴唇方法的技术是评估尿道括约肌的可靠且准确的工具。由于尿道括约肌不是均匀的几何球体，应使用该技术而非数学公式。所报告的技术和数值可能有助于临床医生评估下尿路疾病女性。
