A new dıagnostic tool for assessment of pelvıc dysfunction ın MR defecography

Pelvic floor dysfunction is characterized by incomplete fecal defecation, affecting quality of life in a negative way. Magnetic resonance defecography (MRD) is a useful examination that is ionizing radiation-free and easily reproducible, and which provides anatomical and functional details that are obtainable through multiplanar and dynamic examinations. We aimed to detect pathology using MRD in patients with suspected pelvic floor dysfunction and determine its cause. MRD was performed in 79 individuals. Dynamic images were obtained at rest, straining, and during defecation. Pelvic hiatus mediolateral diameters were compared between groups. Defecation phase provided significantly more accurate results than the straining phase for determining the existence and severity of pathology. Conclusıons: 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.
