Abstract:
Objective To assess the contractility of levator ani muscle in postpartum female using pelvic floor three-dimensional ultrasound and to provide an effective imaging basis for the change of levator ani muscle contractility in postpartum female.Methods Totally 75 postpartum women (55 underwent spontaneous vaginal delivery and 20 underwent selective cesarean delivery) and 40 nulliparas were examined by pelvic floor three-dimensional ultrasound.The images were obtained at rest and at maximal levator ani muscle contraction.The sagittal hiatal length (L) on the two-dimensional sagittal images,the area of levator hiatus (A) and the circumference of levator hiatus (C) were measured on the three-dimensional images,and the difference value between rest and contraction were calculated to get the △L,△A,△C.Then the △L,△A,△C between different groups were compared.Results The △L,△A,△C in spontaneous vaginal delivery group and selective cesarean delivery group were smaller than those in nulliparas group (P ＜0.05),and there was no statistical difference between spontaneous vaginal delivery and selective cesarean delivery group (P ＞ 0.05).Conclusions Three-dimensional ultrasound can effectively assess the the contractility of levator ani muscle,the levator ani muscle contractility of postpartum female was poorer than nulliparas,and between spontaneous vaginal delivery and selective cesarean delivery women there is no obvious difference.
