Summary

Aim of the work This study aims to investigate the relationship between the number of previous cesarean sections (CS) and the incidence of a cesarean scar niche.

Detailed description

Cesarean section (CS) is a common surgical procedure globally, with increasing rates over the past few decades (WHO, 2021). This rise has led to concerns about its long-term complications, including the formation of Cesarean scar niches, also known as isthmoceles (the most common), Cesarean scar defect, Cesarean scar pouch, Cesarean scar diverticulum, Uterine niche and Myometrial defect at cesarean scar. These niches are characterized by discontinuation of the myometrium at the site of the previous CS, often presenting as a hypoechoic area within the lower uterine segment (Elkashef et al., 2023). The prevalence of cesarean scar niches varies widely, ranging from 6.9% to 69%, depending on the diagnostic method used and the population studied (Elkashef et al., 2023; Alassi et al., 2022). In Egypt, the incidence of CS has increased significantly, contributing to a higher risk of niche formation. Recent studies have highlighted a significant relationship between the number of cesarean deliveries and the risk of developing a scar niche, with multiple CS being a major risk factor (Elkashef et al., 2023). For instance, multiple cesarean sections may interfere with tissue perfusion and are associated with increased width and depth of the scar defects (Tilahun et al., 2023). Cesarean scar niches are associated with various clinical symptoms, including abnormal uterine bleeding, chronic pelvic pain, dysmenorrhea, and subfertility, significantly impacting a woman's quality of life (Alassi et al., 2022). The formation of these niches can also lead to complications such as ectopic pregnancies and placenta accreta spectrum disorders (Jauniaux, et al., 2022). Understanding these risks and factors is crucial for developing preventive strategies and managing potential complications.
