Abstract Objective: This study aimed to observe the changes of the anatomical position of the pelvic floor and the thickening rate of the levator ani muscle in the early stage of postpartum, and to explore the effect of different delivery modes on the pelvic floor structure and function in primipara. Methods: One hundred cases(including 50 cases of vaginal delivery and 50 cases of selective cesarean section) of primipara postpartum 6~10 weeks were selected as the study group. Thirty cases of nulliparous women were selected as the control group. The urethral tilt angel(UTA), posterior urethrovesical angel(PUA), bladder neck position(BNP) and cervical mouth position(CMP) were measured at rest and maximum Valsalva operation by two-dimensional perineal pelvic ultrasonography, respectively. The urethral rotation angel(URA), bladder neck descent(BND), cervix down distance(CDD) were calculated and meanwhile the mouth of the urethra was evaluated to be funnel-shaped or not. In addition, the thickness(TN) of the middle levator ani muscle was measured at rest and the maximum contraction state, and the thickening rate(TR) in the middle levator ani muscle was calculated. Results: Compared with nulliparous women, the position of BNP and CMP moved downward, UTA increased, URA, BND and CDD became more mobile, and the levator muscle TR decreased in the primipara, especially in vaginal delivery women. There was a negative correlation between URA, BND, CDD and TR in the control group and the selective cesarean section group. There was no significant correlation between URA, BND, CDD and TR in vaginal delivery group. Conclusion: The perineal pelvic ultrasonography can be used to observe the anatomical structure, location and function of female pelvic organs dynamically.
