Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This study is a multi-center, prospective, observational clinical trial study. 510 full-term pregnant women will be enrolled as subjects, and the ratio of eligible subjects in the two groups is 1:1. In the cesarean section group, full term pregnant women with one prior cesarean section after spontaneous labor who are willing to try the trial of labor after cesarean (TOLAC) and in accordance with the criteria according to the 2016 China vaginal birth after cesarean (VBAC) clinical management guidelines will be enrolled and recorded by our homemade registration form of TOLAC. In the non-cesarean section group, pregnant women after 37 weeks of gestation after spontaneous labor but without vaginal labor contraindications will be enrolled. After spontaneous labor for 24h, their final delivery mode will be recorded. In the following 42 days postpartum, their complications and the neonatal outcome will be followed up.
