Vaginocutaneous fistula and buttock abscess formation 7 years after polypropylene transobturator tape insertion

Surgical treatment for stress urinary incontinence (SUI) using transobturator tape insertion is widely accepted. However, several postoperative complications were reported in the literature including infections, abscess and fistula formation. Here, we report a case of 57-year-old female who presented with abscess and left vaginocutaneous buttock fistula 7 years after transobturator polypropylene tape insertion. Treatment included abscess drainage with dissection of the fistulous tract and removal of the left arm of the transobturator tape along with antibiotic coverage. Sinus drainage stopped after 3 days. Stress urinary incontinence did not recur. Suspicion of fistula formation should rise in patients presenting with bothersome vaginal or cutaneous discharge after transobturator tape insertion. This case is particular since it describes a fistula complication with polypropylene tape, which is unusual with this type of tapes. Treatment of such complication should always consist of surgical removal of the mesh to allow closure of the fistulous tract.
