Comparing Decidual Inclusion vs. Exclusion in Uterine Suture Techniques During Cesarean Section to Improve Scar Thickness and Reduce Isthmocele Risk in Primiparous Women

Starting soon · Not applicable

Conditions studied: Isthmocele, Cesarean Scar Diverticula

In brief

This study compares two ways of closing the uterus during cesarean delivery. In one group, the decidual layer near the uterine cavity is included in the suture. In the other group, this layer is left out. The study will examine whether these two methods differ in how well the uterine scar heals 6 to 9 months after surgery. Women having an elective cesarean delivery will be randomly assigned to one of the two closure methods. Scar healing will be assessed by ultrasound after delivery. The goal is to determine whether one method is associated with better cesarean scar healing and fewer scar defects.
