Methods: Two-hundred and one singleton primiparae without any complications underwent translabial three-dimensional ultrasound at 6 and 18weeks after delivery, with 12 participants lost to follow-up at 18weeks. Fifty nulliparae were enrolled as the control group. Levator hiatal morphology at rest and on Valsalva maneuver was assessed by experienced sonographers, specifically evaluating the anteroposterior diameter, left-to-right diameter, and area. Results: In postpartum women at 6weeks after delivery, all the levator hiatal parameters were significantly higher compared with those of the control group. At 18weeks, the hiatal parameters were better than at 6weeks but still higher than in the nulliparous controls. In all three groups, the hiatal parameters were significantly higher during the Valsalva maneuver than at rest. Conclusions: Postpartum women are prone to develop pelvic floor dysfunction as shown by an enlarged levator hiatus. Translabial three-dimensional ultrasound can be used to effectively assess the morphology and structural alterations of the levator hiatus in postpartum women, providing reliable pelvic floor imaging for early screening, diagnosis, and prevention of pelvic floor dysfunction.
