Translabial ultrasound (TLUS) is an inexpensive, noninvasive imaging modality traditionally used for assessment of pelvic organ prolapse. The utility of TLUS has recently been expanded to the evaluation of synthetic midurethral slings (MUS) surgically implanted for management of stress urinary incontinence. The purpose of this article is to familiarize radiologists with translabial ultrasound technique and provide a technical protocol for TLUS execution because it can be optimized for imaging and assessment of MUS, including identification of MUS configuration and recognition of common complications. This article provides example images of transobturator and retropubic slings and their associated complications, as visualized on TLUS. Accurate imaging and assessment of MUS is helpful in the evaluation of the patient presenting with symptoms suspicious for sling-related complications and in the planning of surgical revision.
Sonographers experience stress-related musculoskeletal injuries at alarming rates. The magnitude of the problem has resulted in substantial economic and human costs. Early efforts, such as the transposition of office ergonomic models to the ultrasound suite, have been only marginally successful because of the vast difference between clerical and sonography work demands. In addition, although the issue has attracted the attention of professional sonographer societies, equipment manufacturers, and governmental agencies, such as the OSHA (Occupational Safety and Health), the causative mechanisms by which sonographers are injured remain inadequately addressed. A definitive ergonomic solution has been elusive. With the help of occupational therapists and biomechanical engineers, we have developed a number of possible ergonomic modifications of ultrasound equipment. We explain the rationale behind these approaches to transducer design and assess the strengths and deficiencies of each.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
