Abscess formation at the ischiorectal fossa 7 months after the application of a synthetic transobturator sling for stress urinary incontinence in a type II diabetic woman

A 50-year-old diabetic woman was referred to our unit because of high fever, foul-smelling vaginal discharge and pain in the leg, 7 months after undergoing surgery for application of a transobturator suburethral sling. Patient evaluation revealed erosion of the tape through the vaginal wall; the infection had spread to the region of the internal obturator muscle and then up to the anterior recess of the ischiorectal fossa. The patient underwent surgery for sling removal, antibiotic therapy and, finally, surgical incisions to facilitate drainage of the abscess. All these passages were necessary to obtain complete resolution of the symptoms. Infectious complications are possible after transobturator sling procedures. Patients should then be informed about the risks of erosion and infection and be warned that the appearance of pain and foul-smelling vaginal discharge may indeed be the first symptom of subsequent and much snore severe infectious complications.
