Prospective Evaluation of the Effect of Thigh Dissection for Removal of Transobturator Mid Urethral Slings on Refractory Thigh Pain

Purpose: Transobturator slings have higher rates of de novo neurologic symptoms than retropubic slings, most commonly related to the thigh. Cases refractory to conservative management may require removal of the thigh portion of the sling. In this series we prospectively examine the effect of thigh dissection with mesh removal on refractory thigh pain.Materials and Methods: All thigh dissections for refractory neurologic symptoms after transobturator sling placement were followed prospectively from October 2012 to October 2015. Patients were assessed preoperatively, with a pain score using a visual analog scale, and postoperatively with a global response assessment.Results: A total of 12 thigh dissections were performed from October 2012 to October 2015 in 8 patients. Mean (±SD) time from original mesh placement to presentation was 2.7 (±1.5) years. Average preoperative pain score was 7.9 (±1.7) out of 10, with pain in the thigh in all patients. Seven cases involved unilateral thigh dissection and 1 had co...
