Abstract
Background
Pelvic floor dysfunction is known to be among the principal factors influencing public health, regarding frequency, cost and effect on women’s quality of life. Radiographic assessment of the pelvic floor function and anatomy plays a vital role in the recognition of pelvic floor defects. The aim of this study is to detect the postpartum-related levator ani muscle changes thus defining the relationship between the vaginal deliveries and the etiology of pelvic floor dysfunction in order to provide guidelines to decrease the incidence of pelvic floor injuries during parturition and guide the treatment plan.
Results
There was a significant difference in the puborectalis muscle thickness between the case and control groups in the right puborectalis (P value ≤ 0.001) and in the left puborectalis (P value (≤ 0.001) as well as significant midpoint thickness (P value = 0.03) with 46.2% puborectalis muscle injury in the case group compared with none in the control group.
Conclusion
Pelvic floor MRI is highly recommended as it is a contrast-free modality that allows for both anatomical and functional analysis. Its incorporation in the routine postpartum assessment will allow early detection of abnormalities even in asymptomatic cases thus ensuring proper management and preventing the development of pelvic floor dysfunction predisposed to by repeated vaginal deliveries.
