Li M, et al. - Researchers tried to find out the application of magnetic resonance defecography (MRD) to assess anatomic and functional pelvic floor disorders in women with stress urinary incontinence (SUI) before and after mid-urethral sling (MUS) intervention. In both SUI individuals, they conducted MRD and continent controls. Static MR was used to describe the anatomic abnormalities in levator ani muscle and periurethral ligaments (PUL). Dynamic MR was applied to describe the function of the urethra and pelvic floor. The MRD parameters were compared between the SUI individuals and continent controls before surgery. The outcomes suggested that MRD with high-resolution and defecation phases gives a detailed anatomic and functional evaluation of the pelvic floor in female SUI before and after pelvic reconstruction.
