Pelvic pain may be caused by disorders of the reproductive, urinary, or gastrointestinal systems. In the pediatric population, pelvic pain is often first evaluated with ultrasonography, with other imaging modalities reserved for further workup or specific indications. Radiologists must be aware of the findings associated with common pelvic emergencies to allow prompt diagnosis and prevention of life-threatening complications. Although the range of pelvic pathology is extensive, this pictorial review presents ultrasound examples of common nontraumatic causes of pelvic pain encountered in the pediatric population, with a brief discussion about multimodality imaging features...

Midurethral sling (MUS) surgical procedures, in which a polypropylene synthetic mesh graft is transvaginally placed to support the urethra and manage stress urinary incontinence (SUI), is commonly performed (Urology. 2013;82(1):38-41; Radiology. 2018;289(3):728-729). Within 10 years of sling placement, about 1 in 20 women undergo subsequent surgery to revise their mesh, in which the mesh is cut or partially excised (Obstet Gynecol. 2019;133:1099-1108). Translabial ultrasound (TLUS) has been described as a sensitive technique for viewing MUS, although few studies have evaluated its ability to view surgically revised MUS (Radiology...
