Abstract: Stress urinary incontinence（SUI） is a common disease in gynecology. There is a higher morbidity of SUI in reproductive and postmenopausal women. SUI is mostly caused by pregnancy and childbirth, which lead to the pelvic floor injury. Women after delivery are in a special period, the pelvic floor has just been hurt during childbirth, and has not been well recovered. So the occurrence of SUI is on a high level after childbirth. To prevent and reduce the occurrence of SUI, we must reveal the etiology of SUI. By analyzing the SUI-related factors, we can find the high risk factors of postpartum SUI, which show us the way to prevent the occurrence of postpartum SUI. After reading related literature, we found that early postpartum pelvic floor muscle training is helpful for preventing and treating postpartum SUI. But there is still insufficient education and lack of aid to access more guidance. Overall, the new mothers require more guidance from community health workers or obstetricians as soon as possible.
