Role of MR Imaging in Evaluation of Pelvic Floor Weakness in Stress Urinary Incontinence in Female

Abstract

The damage to the supporting structures of these compartments leads to SUI. The degree of the disruption of the urethral ligaments and puboperineal muscles should be estimated in the SUI cases to be diagnosed and managed correctly. The conventional ways of diagnosis of pelvic floor dysfunction include voiding cystourethrogram, ultrasound and urodyamic but in recent years with advances in technology MRI proved to be the best to detect the degree of the floor dysfunction and to know which structure is damaged as dynamic MRI can detect and grade the pelvic floor relaxation by using HMO system, estimate width of the Levator hiatus and assessment of the iliococcygeal angle. Endovaginal MRI appears to be the most precise way to know the causing structural damage by imaging the urethra and its anchoring ligaments, detecting and estimating the damage to the pubic component of the Levator ani muscle, and to detect the damage of three levels of fascial support of DeLancey.
