Objective: To explore natural rehabilitation status of pelvic floor function in pluriparas after re-deliver. Methods: A retrospective analysis was performed on the clinical data of 1 052 pluriparas undergoing re-deliver during the period from November 2016 to June 2018 in the hospital. The natural recovery status of pelvic floor function after maternal delivery was analyzed. The occurrence of pelvic floor disorders was recorded. The risk factors were analyzed. Results: Among 1 052 pluriparas undergoing re-deliver, there were 514 cases undergoing cesarean section. And there were 117 cases with pelvic floor dysfunction, with incidence of 22.76%. There were 538 cases undergoing vaginal delivery. And there were 169 cases with pelvic floor dysfunction, with incidence of 31.47%. The incidence of pelvic floor dysfunction in pregnant women undergoing vaginal delivery was higher than that undergoing cesarean section (P<0.05). Logistic regression analysis showed times of pregnancy, weight gain, cesarean section after labor, gestational stress incontinence, and previous vaginal delivery history were independent risk factors for pelvic floor dysfunction in cesarean section puerperae. Logistic regression analysis showed age, times of pregnancy, weight gain, gestational stress incontinence, previous vaginal delivery history, perineal tear, neonatal body mass more than 4 kg, and long first and second stage of labor were independent risk factors for pelvic floor dysfunction in vaginal delivery puerperae. Conclusion: Under natural rehabilitation, incidence of pelvic floor dysfunction is relatively higher. Clinically, intervention measures should be taken to reduce occurrence of postpartum pelvic dysfunction aiming at risk factors of the disease.
