Recurrent Thigh Abscess with Necrotizing Fasciitis from a Retained Transobturator Sling Segment

A woman who underwent transobturator sling surgery for urinary incontinence experienced early vaginal mesh erosion, and underwent a partial sling removal. Several months later, she developed recurrent right thigh and groin abscesses and necrotizing fasciitis. The source of the infection, a retained segment of mesh in the obturator space, was identified only after several operative procedures and referrals. This case illustrates several of the areas of concern with the introduction of new surgical materials and techniques.
