Abstract:
Objective:To explore the relationship between the changes of anorectal angle (ARA) under 3 physiological states and pelvic organ prolapse(POP) in postpartum women by transperineal ultrasound.Methods:The retrospective study enrolled 147 female in 6-8 weeks after delivery examined by pelvic floor ultrasound examinations in Fujian Medical University Second Affiliated Hospital from November 2019 to June 2021, who were divided into POP group and control group. Volume data of pelvic floor ultrasound examinations were obtained at rest, during contraction and during maximal Valsalva maneuver. The differences in the changes of ARA under 3 physiological states between the two groups were compared, and the correlation between the change state of ARA during maximal Valsalva maneuver and POP was analyzed.Results:Compared with ARA at rest, ARA decreased during contraction (χ 2=42.64, P<0.001) and increased during maximal Valsalva maneuver (χ 2=38.43, P<0.001). There was no difference of ARA between the POP group and control group in the 3 physiological states ( P>0.05). However, the risk of POP increased when ARA decreased during maximal Valsalva maneuver ( OR=2.690, 95% CI=1.074-6.739, P<0.05). Conclusions:The decrease of ARA during maximal Valsalva maneuver may increase the risk of POP, and the change of ARA during maximal Valsalva maneuver can be brought into the ultrasonic observation indicators of POP.
