The relationships between the size of the Cesarean scar defect and the clinical symptoms, uterine position and number of previous Cesarean sections were evaluated. Patients with other uterine pathologies, including endometrial hyperplasia, polyps, malignancy and submucosal myomas, were excluded from the study.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>During a 3\u2010year period, 4250 women were assessed by transvaginal sonography, of whom 293 (6.9%) were diagnosed with Cesarean scar defects. Eighty\u2010six patients were excluded due to other uterine pathologies. Altogether, 207 patients with Cesarean scar defects were included in this study. Women who had undergone multiple Cesarean sections tended to have larger scar defects (in width and depth) than did those who had undergone a single Cesarean section. Women with retroflexed uteri also tended to have wider defects than those with anteflexed uteri. Defect width was significantly greater in women with postmenstrual spotting, dysmenorrhea and chronic pelvic pain.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>Multiple Cesarean sections and retroflexed uteri are risk factors for larger Cesarean scar defects. The size of the Cesarean scar defect is associated with clinical symptoms such as postmenstrual spotting, dysmenorrhea and chronic pelvic pain. Copyright \u00a9 2009 ISUOG.
