We report an unusual case of rectal mesh erosion presenting 16 months after robotic sacrocolpopexy. The patient initially underwent a robotic sacrocolpopexy, lysis of adhesions, midurethral sling, and posterior colporrhaphy for symptomatic grade 2 pelvic organ prolapse and urodynamic stress incontinence. Her postoperative recovery was uneventful. Sixteen months later, an anterior 2 × 2-cm rectal mesh erosion was noted on the colonoscopy performed when she presented with hematochezia.
