盆底器官脱垂女性盆膈裂孔的三维超声影像学观察

目的 应用三维超声观察盆底器官脱垂女性盆膈裂孔的形态、结构，探讨三维超声技术评估盆底器官脱垂的应用价值。方法 选取40例盆底器官脱垂女性;同期选择30例未孕、未产的健康妇女作为对照组。两组患者均行经会阴盆底三维超声检查，观察并比较各组妇女的盆膈裂孔的形态、结构、组成及大小。结果 与正常组相比，盆底器官脱垂患者盆膈裂孔形态和结构有明显的差异，表现为盆膈裂孔明显增大，形态由正常的菱形变为类圆形，盆膈裂孔中轴线偏移，裂孔内器官排列有异常，裂孔内结缔组织有缺损表现。结论 三维超声能够有效地对女性盆底结构进行观察，盆底器官脱垂患者存在盆膈裂孔形态和结构的异常。

Three-dimensional ultrasound imaging of the urogenital hiatus in pelvic organ prolapse women

Objective To provide an effective imaging technique for the morphological observation of the urogenital hiatus in pelvic organ prolapse women using three-dimensional ultrasound. Methods In a prospective observational study, forty patients with pelvic organ prolapse and thirty nulliparous women underwent three-dimensional transperineal ultrasound, with the patients supine after bladder emptying. The three-dimensional ultrasound volume was acquired and the form, structure, composition and size of urogeital hiatus were observed in the axial plane set by interior-inferior edge of symphsis pubis and analrectum junction. Results The urogenital hiatus in pelvic organ prolapse women was obviously different from the control's. The size increased sharply, the morphology represented as oval replacing the normal rotundity, the middle line diverged from the normal position, organs inside the hiatus arranged abnormally and the connective tissue defected. Conclusions Three-dimensional ultrasound is an effective imaging method to observe female pelvic floor. Urogenital hiatus in pelvic organ prolapse women displayed abnormities with morphology and structure.
