【摘要】：目的:经会阴三维超声观察不同状态未育正常女性盆底,为女性盆底功能障碍的诊治提供正常值参考。方法:120例未育正常女性,采用经会阴三维超声分别在静息、张力及缩肛状态下观察盆底器官的位置、形态及运动,测量及分析比较盆底三维超声系列生物力学参数。结果:矢状面观察:与静息状态比较,在张力状态膀胱颈到耻骨联合下缘的水平距离绝对值(Dx)增大(P0.01),垂直距离绝对值(Dy)减小(P0.01),而在缩肛状态,Dx减小(P0.01),Dy增大(P0.01)。三维重建图观察:与静息状态相比,盆膈裂孔的左右径、前后径、周长和面积在缩肛状态均减小,而在张力状态均增大(P0.05)。与静息状态相比,耻骨内脏肌厚度在缩肛状态增大,在张力状态减小(P0.05),但耻骨内脏肌角度在缩肛状态及张力状态均增大(P0.05)。在缩肛状态耻骨内脏肌应变值为(-19.11±7.36)%,在张力状态为(19.89±9.28)%。结论:经会阴三维超声能建立盆腔器官运动程度和盆底形态学的正常值参考,是一种有效影像学方法。
[Abstract]:Objective: to observe the pelvic floor of unfertile women in different states by transperineal three-dimensional ultrasound, and to provide a reference for the diagnosis and treatment of female pelvic floor dysfunction. The position, shape and motion of pelvic floor organs were observed under tension and anus contraction, and the biomechanical parameters of pelvic floor three-dimensional ultrasound were measured and compared. Results: sagittal observation: compared with resting state. The absolute value of horizontal distance from bladder neck to lower margin of pubic symphysis increased in tension state, and the absolute value of vertical distance (Dy) decreased P0.01T, while in anus constriction, Dx decreased P0.01Dy and increased P0.01.Three-dimensional reconstruction: compared with resting state, the left and right diameters of pelvic diaphragm foramen were increased. The anteroposterior diameter, circumference and area decreased in anus contraction state, but increased in tension state. Compared with resting state, the thickness of pubic visceral muscle increased in anus contraction state. The strain of pubic visceral muscle decreased in tension state, but increased in anal contraction state and tension state. The strain value of pubic visceral muscle was -19.11 卤7.36 and 19.89 卤9.280.Conclusion: transperineal three-dimensional ultrasound can establish pelvic organ transport. Reference to the normal values of dynamic degree and pelvic floor morphology, It is an effective imaging method.
