采用几何形态测量分析技术评价压力性尿失禁（SUI）患者尿道-阴道界面曲率的差异。我们进行了一项试点病例对照研究，使用磁共振成像（MRI）扫描的18名妇女与非SUI。在尿道中段水平的尿道-阴道界面用二阶多项式回归拟合。利用所得抛物曲线的弦长和弦到顶点的长度来计算拟合界面曲率的圆弧的弧长和半径。收集人口统计学特征和盆腔器官脱垂定量（POP-Q）参数。受试者按照有无SUI、有无前壁脱垂超过处女膜近端2 cm（Aa>-2 cm）进行分层。在有和没有SUI的受试者之间，尿道-阴道界面曲率半径没有差异（8.8 vs 9.2 mm，p=0.53）;然而，在Aa>-2的受试者中，该值较小（8.4 vs 11.9 mm，p=0.03）。有和无SUI的受试者之间以及Aa>-2 cm的受试者和无Aa的受试者之间的弦长、弦顶长度和弧长（包括尿道-阴道界面曲率）相似（所有p>0.05）。在这项初步研究人群中，前阴道壁脱垂超过处女膜近端2 cm的女性中尿道-阴道界面曲率半径较小。未发现有和无SUI的女性尿道-阴道界面曲率的差异。
To evaluate differences in the curvature of the urethral-vaginal interface in women with and without stress urinary incontinence (SUI) using geometric morphometric analysis techniques. We conducted a pilot case-control study using magnetic resonance imaging (MRI) scans of 18 women with and without SUI. The urethral-vaginal interface at the level of the mid-urethra was fitted with a second order polynomial regression. The chord length and chord-to-vertex length of the resulting parabolic curve were used to calculate the arc length and radius of a circular arc fitted to the interface curvature. Demographic characteristics and Pelvic Organ Prolapse Quantification (POP-Q) parameters were collected. Subjects were stratified by those with and without SUI, as well as by those with and without anterior wall prolapse beyond 2 cm proximal to the hymen (Aa>−2 cm). The radius of the urethral-vaginal interface curvature was not found to be different between subjects with and without SUI (8.8 vs 9.2 mm, p=0.53); however, this value was smaller in subjects with Aa>−2 (8.4 vs 11.9 mm, p=0.03). The chord length, chord-to-vertex length, and arc length comprising the urethral-vaginal interface curvature were similar between subjects with and without SUI, and between subjects with and without Aa>−2 cm (p>0.05 for all). In this pilot study population, the radius of the urethral-vaginal interface curvature at the mid-urethra was smaller among women with anterior vaginal wall prolapse beyond 2 cm proximal to the hymen. A difference in the urethral-vaginal interface curvature among women with and without SUI was not found.
