There are different surgical techniques of uterine closure during cesarean. Currently data suggest that the double layer unlocked closure technique is associated with better uterine scar healing, and this technique is considered the gold standard.

This study compares two techniques of uterine closure on myometrium thickness:

1. Double layer unlocked suture;
2. Purse suture of the uterus with a first continuous purse suture of the deep portion of the myometrium and a second unlocked continuous suture including the remaining part of the myometrium.

The primary outcome is the mean residual myometrium thickness at the site of the uterine scar evaluated by transvaginal ultrasound at six months after cesarean.
