Evaluation of anatomical changes dynamically by magnetic resonance defecography according to pelvic floor dysfunction types
Key Points
Combined prolapse is linked to increased H line, M line, and anorectal angle values during straining.
During rectal evacuation phases, these anatomical changes are significantly different, indicating the impact of dysfunction.
Dynamic magnetic resonance defecography (MRD) effectively measures these anatomical alterations in real-time.
Findings may inform clinical approaches for patients with pelvic floor dysfunction, though further research is warranted.
Abstract
Dynamic MRD demonstrated that combined prolapse is associated with greater H line, M line, and anorectal angle values, which increase significantly during the straining and rectal evacuation phases.
