Summary:Purpose To examine the changes in the pelvic floor structure caused by pregnancy and delivery. Methods A total of 141 nulliparous women were examined with three-dimensional transperineal ultrasound (3D-TPU) at the 24th and 34th weeks of gestation, 5th day postpartum, and 1 month postpartum. Puborectalis muscle trauma was diagnosed and the area of levator hiatus (ALH) was measured. Results One hundred and five normal vaginal deliveries, 19 vacuum/forceps deliveries, and 17 cesarean deliveries were included. In the normal delivery group, the rate of puborectalis muscle trauma was low and showed no significant change between the 24th and 34th weeks of gestation (12.5% vs. 17.2%, p  = 0.42). The rate of trauma significantly increased to 70.2% at the 5th day postpartum ( p
