To investigate the effects of Buzhong Yiqi Pills in the treatment of postpartum pelvic floor dysfunction(PP）and its influence on urodynamic indexes and sexual function.Methods:A total of 94 cases of postpartum pelvic floor dysfunction were selected from Henan Rongjun Hospital from June 2015 to June 2017.They were randomly divided into the observation group(47 cases）and the control group(47 cases）according to random number table.Patients in the control group had the pelvic floor muscles exercised，and the observation group was treated with Buzhong Yiqi Pills in addition to the same exercise as the control group.The treatment course of the 2 groups were 12 weeks.After the treatment，the curative effects of the 2 groups were compared：the recovery of the pelvic floor muscle strength and sexual function before and after the treatment，as well as the changes in urodynamic indexes.Results:The total effective rate of treatment in the observation group(91.49%）was higher than that of the control group(72.34%)(P<0.05).After treatment，the pelvic floor muscle strength of both group was>III，higher than before(P<0.05)，and the pelvic floor muscle strength in the observation group was higher than that of the control group(P<0.05).The maximum bladder capacity and maximum urinary flow rate in the observation group were higher than that of the control group(P<0.05).Sexual life and orgasm frequency of both group increased after treatment(the observation group：t=29.987，24.200，the control group：t=15.540，22.182，P<0.05); the frequency of sexual life and orgasm of the observation group was higher than that of the control group(t=15.058，10.661，P<0.05).Conclusion:The therapeutic effect of Buzhong Yiqi Pills in the treatment of postpartum pelvic floor dysfunction is significant，and also，it can improve the urodynamics and sexual function of the patients，which is of research significance.
