Abstract：Objective To evaluate postpartum pelvic floor disorder through assessing the pelvic floor func -tion and compare the effects of two kinds of delivery modes , cesarean section and vaginal delivery on postpartum pel-vic floor function and provide a theoretical basis for the prevention and treatment of pelvic floor dysfunction (PFD). Methods 800 postpartum women who revisited the outpatient department 6 to 8 weeks after childbirth were collected from January to June 2014 and divided into caesarean delivery group (n=288) and vaginal delivery group(n=512) according to the different modes of delivery .Routine assessment of pelvic floor function was retrospectively analyzed and compared between the two groups .Results Among 800 patients who were screened by the manual muscle test combined with the assessment of pelvic floor function .The damage of muscle fiber type Ⅰwas found in 185 cases and the damage of muscle fiber type Ⅱin 168 cases in the cesarean delivery group;the damage of muscle fiber type Ⅰwas found in 504 cases and the damage of muscl fibere type Ⅱin 502 cases in the vaginal delivery group .There was significant difference between the two groups (P<0.01).The impaired muscle strength, muscle injury, abnormal muscle fatigue and the vaginal dynamic pressure value <80 cmH2 O were more severe or higher in vagina delivery group than those in the caesarean delivery group (P<0.05).Conclusion Compared with vaginal delivery , cesarean section has less adverse effects on pelvic floor function .However , the impaired pelvic floor function can be recovered by carrying out postpartum rehabilitation exercise , so it should not be based on the choice of delivery modes .
