Pelvic organs prolapse recurrence after surgery using static and dynamic MRI

As high as 54% is the anatomical recurrence rate following hysterectomy with anterior and posterior vaginal wall restoration for pelvic organ prolapse (POP). The levator ani muscle (LAM) is the primary pelvic floor support system. Using static and dynamic MRI, we investigated the association between the morphology and function of LAM and the postoperative recurrence of POP. Risk factors for the recurrence of POP included the thickness and injury of the LAM at rest, the H line, the M line, and the size of the levator hiatus at rest and strain, as well as the variation of the levator hiatus during the Valsalva maneuver.
