Groin granuloma formation after midurethral sling.

BACKGROUND

Complications of midurethral transoburator slings include injuries directly associated with trocar placement or subsequent erosion of the mesh that is placed. While tissue reaction to implanted mesh material occurs, rarely does it produce clinical symptoms. We report a case of granuloma formation after a transobturator tape midurethral sling presenting as a groin mass.

CASE: A 59-year-old para 2 postmenopausal woman underwent uncomplicated placement of a transobturator tape midurethral sling concomitantly with prolapse repair. Two years later, she presented to her primary care physician complaining of a 1-cm groin mass. After failure of empiric treatment with antibiotics for a presumed infectious etiology, surgical resection of the mass was performed, which revealed granuloma formation surrounding the polypropylene mesh.

CONCLUSION

Granuloma formation can occur years after placement of a midurethral transobturator sling. Whereas a rare complication, it is important for surgeons to consider this diagnosis during the workup of a groin mass.
