Abstract To investigate the influence of the different delivery modes of primiparas on their short-term anterior pelvic function evaluated by the pelvic floor ultrasonography quantitatively. Methods: The clinical data of 102 primiparas who had undergone the pelvic floor examination by ultrasound from June 2022 to December 2023 were collected. According to the different delivery modes, these primiparas were divided into group A (58 primiparas with vaginal delivery) and group B (44 primiparas with cesarean section). The short-term anterior pelvic function of the primiparas in the two groups were evaluated quantitatively by pelvic floor ultrasound. The values of the pelvic floor ultrasound parameters and the incidence of abnormal anterior pelvic function of the primiparas were compared between the two groups. Results: There were no significant differences in the maternal age, the body mass index and the neonatal length of the primiparas between the two groups (P>0.05). There were no significant differences in the bladder neck distance (25.1±4.4 mm vs. 25.6±4.2 mm), the posterior bladder angle value (117.6±6.8 °vs. 118.2±7.5 °), the urethral tilt angle value (29.1±2.4 °vs. 28.2±2.5 °) of the primiparas between the two groups (P>0.05). The values of the maximum Valsalva ultrasound parameters, such as the bladder neck descent (27.17±7.38mm), the posterior bladder angle (132.91±10.57 °) and the urethral tilt angle (53.82±12.35 °), of the primiparas in group A were significantly higher than those (15.26±6.14mm, 124.93±9.18 °and 34.71±10.02°) of the primiparas in group B. The incidence of the cystocele (53.5%) of the primiparas in group A was significantly higher than that (27.3%) of the primiparas in group B, and the incidence of the internal urethral orifice dilatation (19.0%) of the primiparas in group A was significantly higher than that (4.6%) of the primiparas in group B (all P<0.05). Conclusion: The pelvic floor ultrasound can effectively and quantitatively evaluate the changes of the anterior pelvic structure and function of the primiparas with the different delivery modes, and the changes of the pelvic structure and function of the primiparas with vaginal delivery are greater than those of the primiparas with cesarean section.
