Uterine Niche After Cesarean Section

In the past decade several articles have described a defect that can be seen on ultrasound at the site of cesarean delivery scar, known as a 'niche' .An incompletely healed scar is a long-term complication of cesarean delivery and is associated with symptoms such as postmenstual spotting, dysmenorrhoea, chronic pelvic pain dyspareunia and subfertility. This study aimes to evaluate the prevalence of niche in a large cohort study after long term follow up since operation, and characterize the risk factors for its development and for symptoms to appear.
