Abstract：Objective: To investigate the incidence of postpartum stress urinary incontinence(SUI) and analyze its influencing factors. Methods: A total of 836 women who gave birth at the Second Hospital of Anhui Medical University from December 2017 to December 2018 and were given 6-8 weeks postpartum assessment of pelvic floor muscle strength were selected.The postpartum women were divided into SUI group (n=294) and non-SUI group (n=542) according to the questionnaire survey used to investigate the incidence of postpartum urinary incontinence. The clinical data of the two groups were compared retrospectively, and the influence of related factors on postpartum SUI was analyzed. Results: The incidence of SUI in postpartum women was 35.2% and the pelvic floor muscle strength in SUI group was significantly lower than that in non-SUI group (P<0.05). Univariate analysis: the maternal age, gravidity, parity, the number of abortions, prenatal weight, prenatal body mass index (BMI), weight gain during pregnancy, mode of delivery, SUI during pregnancy,pregnancy and postpartum complications, newborn birth weight, macrosomia showed significant difference. Logistic regression showed that parity, prenatal BMI, mode of delivery, SUI during pregnancy, newborn birth weight, macrosomia, pregnancy and postpartum complications were all independent risk factors for postpartum SUI (P<0.05). Conclusion: Postpartum SUI is related to various factors of pregnancy and childbirth. Controlling pregnant women's weight gain during pregnancy and reducing prenatal BMI can reduce the incidence of postpartum SUI.
