Minimal Invasive Management of Cesarean Scar Niche: Review Article

Abstract

Worldwide, rates of caesarean section are rising. The term ‘niche’ describes the presence of an hypoechoic area within the myometrium of the lower uterine segment, reflecting a discontinuation of the myometrium at the site of a previous caesarean section. A defect in caesarean section scar is associated with symptoms like abnormal uterine bleeding, infertility and complications in subsequent pregnancy including: risk of rupture and morbidly adherent placenta. It can also increase rates of complications during gynaecological procedures: IUCD insertion, evacuation of retained products of conception, hysteroscopy and risk of ectopic pregnancy at scar site.
