Wound healing status when closed by a single layer of interrupted sutures

A: The wound thickness in MRI images after transverse uterine fundus incision in the early stages of TUFI development that was ≤ 30% of the thickness of the surrounding muscle layer

Arrow: the scar from the transverse uterine fundal incision

B: Schematic drawings indicate that the uterine muscle was pulled in both directions, suggesting that strong postpartum uterine contractions prevented wound healing
