Cross-sectional imaging following surgical interventions for stress urinary incontinence in females.

Stress urinary incontinence (SUI) is a condition in which the weakness of the pelvic floor muscles causes unintentional loss of urine. For patients who are unable to achieve symptomatic improvement from lifestyle modification and pharmacotherapy, surgical placement of the pelvic slings or the use of urethral bulking agents has been shown to provide tremendous symptomatic improvement. Learning to recognize the pelvic slings and to identify their complications on imaging is invaluable; however, this is challenging because of the change in the local anatomy after surgical placement of the sling. In this paper, we present CT and MR imaging to demonstrate the surgical and non-surgical treatments of female SUI and their complications. Through this pictorial essay, our goal is to familiarize radiologists with recognizing the various forms of treatment for SUIs, the relevant pelvic anatomy, and complications that may occur secondary to the surgical placement of the pelvic slings.
