Ultrasound imaging of slings and meshes in urogynecology

Imaging is used increasingly in urogynecology. One of the main applications is in the assessment of synthetic implants. Ultrasound is particularly useful for this purpose as most such implants appear highly echogenic on ultrasound but are not visible using other imaging techniques. The worldwide success of synthetic mid-urethral slings, introduced in the late 90s, led to the subsequent introduction of transvaginal mesh in 2003-2004. Widespread use of synthetic implants for both urinary incontinence and prolapse has caused a rise in implant-related complications and increasing negative publicity and litigation, with many products removed from the market. It is not surprising that there is increasing demand for the assessment and evaluation of sling and mesh implants using imaging. This review article discusses the role of translabial/transperineal ultrasound in the evaluation of synthetic implants used in the treatment of urinary incontinence and pelvic organ prolapse. The discussion focuses on those applications of the technique that are useful for surgeons dealing with patients after mesh and/or sling placement.
