BACKGROUND This single-center study involved 33 women diagnosed with pelvic organ prolapse (POP), aiming to evaluate the levator ani muscle (LAM) using pre- and post-surgery magnetic resonance imaging (MRI). MATERIAL AND METHODS MRI data of 33 women were analyzed before and after POP surgery. Diagnoses used the Pelvic Organ Prolapse Quantification (POP-Q) system, including 10 cases of stage II, 5 of stage III, and 18 of stage IV with pelvic organ prolapse. All participants underwent pelvic floor reconstruction surgery. Morphological parameters, including the levator hiatus's length, width, area, and the distance between the LAMs and the pubic symphysis's inferior point, were assessed before and after surgery. RESULTS Significant pre- and post-surgery differences were observed in the levator hiatus's shape, length, width, and area, and the distance between levator ani and pubic symphysis in both static and Valsalva states. CONCLUSIONS We found structural changes in the LAM morphology in women with POP, as assessed by MRI, suggesting potential improvements in clinical function.
背景 这项单中心研究纳入了33名被诊断为盆腔器官脱垂（POP）的女性，旨在通过术前和术后磁共振成像（MRI）评估肛提肌（LAM）。材料与方法 对33名女性POP手术前后的MRI数据进行分析。诊断采用盆腔器官脱垂定量（POP-Q）系统，其中盆腔器官脱垂II期10例、III期5例、IV期18例。所有参与者均接受盆底重建手术。评估手术前后包括肛提肌裂孔的长度、宽度、面积以及肛提肌与耻骨联合下点之间距离在内的形态学参数。结果 在静息和Valsalva状态下，肛提肌裂孔的形状、长度、宽度和面积以及肛提肌与耻骨联合之间的距离在手术前后均存在显著差异。结论 我们发现，通过MRI评估，POP女性的肛提肌形态存在结构变化，提示临床功能可能得到改善。
