骨性产道与盆腔器官脱垂：基于MRI对盆腔中平面尺寸的定量评估

推荐 为探究骨性产道尺寸与盆腔器官脱垂（POP）的关联，来自未提及单位的研究人员开展病例对照研究，利用3D MRI模型对比有、无POP的生育期女性盆腔中平面骨性尺寸。结果显示，POP患者该部位尺寸更大，且与脱垂程度相关，为临床诊断提供新依据。

　　

The bony birth canal dimensions are hypothesized to be related to pelvic organ prolapse (POP). However, the pelvic mid - plane, the narrowest obstetrical plane, has not been fully studied. This study aimed to compare the bony dimensions at the pelvic mid - plane level between childbearing women with and without POP using 3D MRI models and evaluate their association with POP. Data from 131 POP patients were prospectively collected between 2021 and 2023, and 85 cases were matched with 85 controls with similar demographic characteristics. A case - control study was conducted. The results showed that there were significant differences in multiple bony dimensions at the pelvic mid - plane between the two groups. A larger pelvic mid - plane was significantly associated with an increased risk of prolapse, and among POP patients, those with a larger pelvic mid - plane area had more severe prolapse.
