Obstructed defecation (OD) is common and may be related to compromised pelvic floor integrity. Magnetic resonance (MR) defecography and statistical shape modeling were used to define pelvic floor shape variations, hypothesizing that State (rest vs peak evacuation) and Group (control vs case) would significantly influence shape. 16 women underwent MR defecography (9 cases vs 7 controls). Midsagittal, 2D pelvic floors were segmented and aligned by corresponding points. Principal component scores were compared using a Two-Way Mixed MANOVA. Three modes described differences between State (p < 0.001) and Group (p = 0.023). The pelvic floor shape differed significantly between women with and without OD and during evacuation.

盆底形状统计模型评估女性排便障碍症状

排便障碍 (OD) 很常见,可能与盆底完整性受损有关。磁共振 (MR) 排粪造影和统计形状建模用于定义盆底形状变化,假设状态(休息与高峰疏散)和组(对照组与病例)将显着影响形状。16 名女性接受了 MR 排粪造影(9 例 vs 7 例​​对照)。正中矢状面,二维骨盆底通过相应的点进行分割和对齐。使用双向混合多元方差分析比较主成分分数。三种模式描述了状态 (p < 0.001) 和组 (p = 0.023) 之间的差异。有和没有 OD 的女性以及疏散期间的骨盆底形状显着不同。
