本研究的目的是比较 MRI 上患有主要肛提肌 (LA) 缺陷和盆腔器官脱垂 (POP) 的女性与具有正常 LA 肌肉和正常支撑的女性的耻骨直肠肌肉完整性和体积。这是一项病例对照研究，将 24 例已知主要 LA 缺陷和 POP 的病例与 24 例具有正常 LA 和正常支持的对照进行比较。骨盆的轴向 T-2 加权 MRI 扫描评估了耻骨直肠肌肉的完整性和肌肉体积的程度。年龄、体重指数、阴道分娩或子宫切除状态没有显着的组间差异。在所有 48 名受试者中，耻骨直肠肌都是可见的，并且没有发现任何破坏。各组之间的肌肉体积没有差异（对照/病例，瘦42% vs. 25%，平均42% vs. 38%，厚17% vs. 38%；P=0.47）。对于患有严重 LA 缺陷和 POP 的女性，MRI 未发现耻骨直肠肌缺陷和肌肉体积损失。
The objective of this study was to compare puborectal muscle integrity and bulk in women with both major levator ani (LA) defects on MRI and pelvic organ prolapse (POP) to women with normal LA muscle and normal support. This is a case-control study comparing 24 cases with known major LA defects and POP to 24 controls with normal LA and normal support. Axial T-2 weighted MRI scans of the pelvis were evaluated for integrity of the puborectal muscle and degree of muscle bulk. There were no significant group differences in age, body mass index, vaginal deliveries, or hysterectomy status. In all 48 subjects, the puborectal muscle was visible and had no disruption noted. There was no difference in muscle bulk between groups (control/case, thin 42% vs. 25%, average 42% vs. 38%, thick-17% vs. 38%; P=0.47). Defects and loss of muscle bulk in the puborectal muscle are not seen on MRI in women with major LA defects and POP.
