MR Defecography in Assessing Functional Defecation Disorder: Diagnostic Value of the Defecation Phase in Detection of Dyssynergic Defecation and Pelvic Floor Prolapse in Females

Conclusion: The straining phase and the defecation phase have the same ability in assessing paradoxical puborectalis contraction of the DD. Compared with the straining phase, the defecation phase provides the maximum stress to the pelvic floor resulting in complete levator ani relaxation. In addition to diagnosing the abnormal anorectal function, the defecation phase with the discharge of the rectal filling demonstrates maximum anterior/middle pelvic organ descent in DD patients.Digestion
