经会阴二维超声动态观察和评估未育女性盆底

Dynamic observation and evaluation on pelvic floor in nulliparous women with trans-perineum two-dimensional ultrasound

目的应用经会阴二维超声动态观察并评估未育女性盆底器官的形态、位置及运动,探索一种可有效观察盆底器官的影像学方法。方法对50例未育女性行经会阴二维超声检查,分别在静息期、缩肛期和张力期动态观察盆底器官的形态、位置及运动,并获取位置的测量参数。结果经会阴二维超声可清晰显示未育女性盆底器官的形态和位置。盆底器官静息期位于参照线头侧,缩肛期向头腹侧移动,张力期向足背侧移动,但始终位于参照线头侧;盆底器官有一定的向正常方向的移动度。结论经会阴二维超声能清晰地显示女性盆底器官的形态、位置及运动,是一种有效的影像学方法。

Objective To dynamically observe and evaluate the shape,position and movement of pelvic floor organs in nulliparous women with trans-perineum two-dimensional ultrasound,and to seek for effective imaging method for pelvic floor.Methods Trans-perineal two-dimensional ultrasound was performed on 50 nulliparous women to observe the shape,position and movement of pelvic floor organs during quiet period,anus-contracting period and tension period.Linear parameters of location were measured.Results The shape and position of pelvic floor organs of nulliparous women were clearly displayed.Pelvic floor organs located at the head side of the reference line in quiet period,but moved to the cephalic and ventral direction during anus-contracting period while to the caudal and dorsal direction during tension period.Pelvic floor organs could move appropriately towards the right direction.Conclusion The trans-perineum two-dimensional ultrasound can clearly display and estimate the shape,location and movement of nulliparous women＇s pelvic floor organs.It is an effective imaging pattern to observe pelvic floor.
