Pain as the Sole Presenting Symptom of Infected Sacral Nerve Stimulation Implantable Pulse Generator

Abstract

Two patients presented from outside hospitals with complaints of pain at the site of implantable pulse generator (IPG). Neither patient had constitutional or local signs and symptoms of infection; however, during operations performed for revision and/or troubleshooting of the device, infection was encountered and all components were removed. Both individuals recovered well from the operation, and one patient underwent subsequent placement of a new InterStim device with good results. Possibility of infection should be considered in patients with complaint of pain associated with IPG site.
