Real time three-dimensional ultrasound in assessment of pelvic floor organ movement and levator hiatus in postpartum women / 中国医学影像技术

ABSTRACT

Objective To observe and evaluate the location of the three compartments of the pelvic floor organ and levator hiatus area in the postpartum women by transperineal real time three-dimensional ultrasound.Methods Sixty eases of maternal with the matching age and body mass index (BMI;postpartum group) and 35 non-fertile women (control group)were selected.The distance between the lower edge and the reference line was measured by the transperineal ultrasound at rest and Valsalva movement in the lowest point of bladder,cervix and rectum.Meanwhile,the area of levator hiatus under Valsalva action was measured by real time 3-dimensional ultrasound.The differences were compared between two groups.Results In the postpartum group,the lowest point of the bladder and cervix was lower than the control group at rest and Valsalva movemen (both P＜0.05).Rectum location in the rest state difference between the two groups had no statistical significance (t=0.405,P =0.398).The area of the levator hiatus of the postpartum group was significantly larger than that of the control group at the rest and Valsalva movement (t=11.253,9.625,P＜0.001).Conclusion Transperineal real time 3-dimensional ultrasound can dynamically observe the position,movement of pelvic floor organ and the area of levator hiatusin of the female.To evaluate the pregnancy and childbirth have obvious effect on the pelvic floor support tissues.
