Removal of Mini-Sling Anchor With Magnetic Resonance Imaging-Guided Site Marking With Methylene Blue.

Abstract

<h4>Background</h4>Single-incision midurethral slings are an alternative to standard midurethral slings for the treatment of stress urinary incontinence. Single-incision midurethral slings use less mesh, relying on soft tissue anchors for mesh stabilization, but can be associated with chronic pain.<h4>Case</h4>We describe the novel use of magnetic resonance imaging to localize and stain a retained radiolucent single-incision midurethral sling anchor with methylene blue dye. This assisted the transvaginal dissection for removal of the stained anchor for a patient with persistent chronic pelvic pain after a prior mesh removal.<h4>Conclusion</h4>Marking the target anchor with dye provided crucial intraoperative guidance for the surgical dissection. This technique can be a valuable tool for localizing surgical targets that are radiolucent.
