Abstract

One suggested rationale for using MR imaging to evaluate urinary incontinence and pelvic floor dysfunction derives from the observation that patients might present with symptoms isolated to one pelvic compartment, but may have concomitant defects in other compartments (Maglinte et al. 1999). Accurate diagnosis of coexisting abnormalities is essential in planning reconstructive pelvic floor and antiincontinence surgery. Some authors have suggested that surgical failures result from the lack of thorough preoperative diagnosis and inadequate staging of pelvic floor dysfunction (Safir et al. 1999).
