Pelvic floor ultrasound in the diagnosis of sling complications.

PURPOSE: The mid-urethral synthetic sling (MUS) procedure has become the standard of care for treatment of female stress urinary incontinence. However, a small number of patients will have complications following MUS including failure, obstructive voiding, sling erosion, or chronic pain. This paper discusses the role of 2D and 3D ultrasound imaging in the evaluation of the female patient with complications following placement of a synthetic mid-urethral sling. RESULTS: The MUS is easily visualized as an echogenic structure on ultrasound and can be imaged by transperineal, transvaginal and introital approaches. Ultrasound allows dynamic assessment of the sling and can assist in the diagnosis of sling failure, obstruction, erosion and mesh related pain. CONCLUSIONS: Pelvic floor ultrasound has an emerging role in the assessment of complications following MUS surgery. 3D ultrasound can assist the clinician in assessment of the complex patient with multiple slings or meshes in situ.
