Acute and serious myositis with abscess in thigh muscle after transobturator tape implantation.

The complications of transobturator tape (TOT) were known as lower urinary tract injury, postoperative urinary retention, urge incontinence, vaginal erosion, and etc. A 63-year-old woman presented with new onset of severe pain, heating, and swelling of the left thigh and perineum. She had undergone TOT implantation for stress urinary incontinence (SUI) 4 days previously in an outside clinic. Painful left thigh swelling and skin erythema were noted on the physical examination. A computed tomography (CT) scan showed multiple, large left medial thigh and obturator abscesses. Removal of the implanted tape and abscess drainage were performed immediately and two additional operations were needed for proper abscess drainage. We believe this case to be one of the most serious complications to occur since the introduction of the TOT procedure. Here we report this case and discuss its initial management along with a review of the literature.
