Effect of different delivering methods on pelvic floor function in vaginal delivery / 中国医学影像技术

ABSTRACT

Objective To explore the effect of different delivering methods on the pelvic floor function in vaginal delivery by transvaginal three-dimensional ultrasound.Methods Eighty-four patients delivered transvaginal were classified into three groups according to the mode of delivery (perineal integrity group [n=32],episiotomy group [n=30] and forceps delivery group [n=22]).The hiatal images at resting,Valsalva,levator ani muscle maximum contraction were obtained and compared in three groups.Results There were no differences between perineal integrity group and episiotomy group in hiatal diameter and area (P＞0.05).There were significantly differences between perineal integrity group and forceps delivery group in hiatal diameter,area and change in hiatal area from rest to pelvic floor muscle contraction and from rest to Valsalva (all P＜0.05).Conclusion The injury of the pelvic floor of forceps delivery group is bigger than perineal integrity.And episiotomy is no significant difference with pelvic floor function injury.
