Abstract
Background: Pelvic floor dysfunction is characterized by incomplete fecal defecation, negatively affecting the quality of life. Magnetic resonance defecography (MRD) is a useful examination that is ionizing radiation-free and easily reproducible, and provides anatomical and functional details that are obtainable through multiplanar and dynamic examinations. The study aims to detect pathology using MRD in patients with suspected pelvic floor dysfunction and determine its cause.
Methods: MRD was performed on 79 individuals. Dynamic images were obtained at rest, straining, and during defecation. Pelvic hiatus mediolateral diameters were compared between groups.
Results: The defecation phase provided more accurate results than the straining phase for determining the existence and severity of pathology significantly.
Conclusion: The defecation phase is the most accurate phase for identifying the existence and severity of pathology, as the pelvic hiatus mediolateral diameter is thought to be an important factor in triggering pelvic dysfunction.
