Currently, there is an increase in the frequency of cesarean sections, and the number of young fertile women with a scar on the uterus rises as well. The presence of any scar on the uterus is always a risk for reproductive complications. If there is a severe myometrial defect, it can lead to thinning of the myometrium of less than 3 mm and formation of a defect on the part of the uterine cavity (niche). This article discusses the issues of terminology, the causes of formation and the clinical consequences of the defects in the scar area. Uterine rupture along the scar during pregnancy and childbirth is a life-threatening complication that can occur in the absence of timely diagnosis and treatment of this pathology in women planning a pregnancy. Modern algorithms for diagnosis and choice of treatment tactics depending on the clinical and instrumental results of the examination are presented in the article. Ultrasound examination, sonography, MRI, hysteroscopy are the main methods for diagnosing pathology in the area of the uterine scar after cesarean section. Depending on the clinical symptoms, the patient’s reproductive plans and the location of the defect, both dynamic observation and surgical correction of the uterine scar are possible. Hysteroscopic niche resection and metroplasty are the main methods of surgical treatment of patients with uterine scar defects.
Conclusion: The comprehensive examination of women with a uterine scar after cesarean section, the combination of at least two examination methods (ultrasound and MRI) can significantly increase the accuracy and quality of diagnosing the condition of the postoperative uterine scar. The choice of treatment for defects in the area of the uterine scar after cesarean section depends on the severity of clinical symptoms, the woman’s reproductive plans, the characteristics and localization of the myometrial defect in the area of the scar. Reconstructive surgery on the uterus (metroplasty) makes it possible not only to improve the quality of a woman’s life and restore fertility, but most importantly it can reduce the risks of life – threatening complications during pregnancy.
