Pelvic floor dysfunction, including both pelvic floor relaxation and pelvic organ prolapse, can lead to any combination of urinary or defecatory dysfunction, organ prolapse, and/or pelvic pain. Unfortunately, treatment failure is common - over 50% of patients presenting with pelvic floor dysfunction may have already undergone a failed intervention. Surgical intervention usually involves the placement of a pelvic sling, a procedure with a complication rate (pain and/or perforation) of approximately 10%. US and MR provide both anatomic and functional information for pre-procedural planning and post-operative problem solving, especially in the evaluation of mesh fragments. These dynamic imaging techniques provide reproducible and quantifiable means of diagnosis to triage patients to surgical intervention, follow patients after surgery, and evaluate failed interventions. Through multimodality imaging review and clinico-pathologic correlation, this exhibit will help radiologists understand surgically relevant pelvic floor anatomy, pelvic floor disorders, and the appearance of common implant and surgical techniques to improve performance and interpretation of dynamic pelvic floor imaging.
