The purpose of this study was to explore the relevant factors that affect the risk of cesarean scar diverticulum (CSD).A retrospective, case-control study was designed among women with a history of cesarean section (CS) who were admitted in Zhejiang Tongde Hospital from January 2017 to December 2019. Women with missing information were excluded. The basic clinical characteristics and the risk factors for CSD were assessed using univariate analysis and multivariate logistic regression analysis.A total of 216 women were analyzed, including 87 patients with CSD and 129 cases without CSD as control. Significant differences in number of CS, trial of labor (elective or urgent CS), CS interval, uterine position, intraoperative hemorrhage, and dysmenorrhea between CSD group and control group (P < .05). Multivariate logistic regression analysis showed that number of CS, trial of labor, interval of CS, and uterine position were independent risk factors of CSD.In women with a history of CS, multiple cesarean deliveries, elective CS, cesarean interval of less than 5 years, and retroflexed position of the uterus may be associated with an elevated risk of CSD.
