Objective To investigate the current situation of urine leakage symptoms in postpartum women, to explore the influencing factors of postpartum urine leakage, and to provide basis for prevention and early evaluation of urine leakage symptoms. Methods Convenience sampling method was used to collect the demographic data, pelvic function data, and postpartum urine leakage data from 717 women (42-60 postpartum days) who visited the outpatient department of Peking University People′s Hospital for postpartum review from February through December 2019. Results Among the 717 postpartum women, 130 had symptoms of urine leakage, with an incidence rate of 18.13%. The results of univariate analysis showed that such 8 factors as age, number of vaginal delivery, mode of delivery, urine leakage during pregnancy, genital hiatus（gh）measurements, strength of type I&II pelvic floor muscle, and stage of POP-Q, were associated with postpartum urine leakage（P<0.05, P<0.01）. Logistic regression analysis showed that age, vaginal delivery, forceps delivery, type I muscle strength and urine leakage during pregnancy were determinants of postpartum urine leakage（P<0.05,P<0.01）. Conclusion The prevalence rate of urine leakage in postpartum 42-60 days is at a high level, and increased age, vaginal and forceps delivery, weakened strength of type I muscle and urine leakage during pregnancy increase the probability of postpartum urine leakage. Clinical medical staff should assess and screen these influencing factors early on in order to reduce the incidence of postpartum urine leakage.
