Perineal ultrasound in evaluation of the effects of different delivery methods on pelvic floor organ prolapse in early postpartum period

Abstract

Objective To observe the changes of the anatomical position of pelvic floor organs in the early postpartum period by transperineal pelvic floor ultrasound, so as to investigate the influence of vaginal delivery and cesarean section on prolapse of pelvic floor organs in transineal women. Methods A total of 110 perinatal women (55 cases in transvaginal delivery group and 55 cases in cesarean section group) at 5 to 10 weeks after delivery who were examined in the Outpatient Department of Meizhou People’s Hospital from January 2018 to January 2019 were selected as the study group, and 30 healthy and childless women were selected as the control group during the same period. Two-dimensional transperineal pelvic floor ultrasound was used to measure posterior urethrovesical angle (PUA), bladder neck position (BNP), cervical mouth position (CMP), urethral rotation angel (URA), bladder neck descent (BND), cervix down distance (CDD). And the infundibulation of the urethra was observed. Results Compared with control group, BNP and CMP position decreased in vaginal delivery group and cesarean section group, however, URA, BND and CDD activity increased in vaginal delivery group and cesarean section group, and the difference was statistically significant (P 0.05). Conclusions Transperineal two-dimensional pelvic floor ultrasound can be used to observe the anatomical structure, position and functional status of female pelvic organs dynamically, and evaluate the degree of early pelvic floor organ prolapse in postpartum women. The main influencing factor of pelvic floor structure and function of multipara is pregnancy, nor delivery mode.
