简要总结
Uterine niche is a defect formed by poor healing of the lower uterine myometrium after cesarean section, defined as a depression of at least 2mm in the uterine myometrium at the cesarean scar; it is associated with gynecological symptoms and even life-threatening pregnancy complications, so accurate imaging evaluation is crucial for diagnosis, symptom grading, and treatment planning. Currently, transvaginal ultrasound (TVS), saline hysterosonography (SHG), and magnetic resonance imaging (MRI) are commonly used for evaluation, but there are controversies about the consistency of their measurements and repeatability of results. This observational study, conducted at the International Peace Maternity and Child Health Hospital affiliated with Shanghai Jiao Tong University School of Medicine, included women diagnosed with uterine niche.
