Unusual cause of dysuria: migration of a pacemaker generator into the urinary bladder.

Following pacemaker implantation, a 71-year-old female developed infection of the generator pocket. Five years after relocation posterior to the rectus muscle she suffered from cystitis. Cystoscopy revealed the pacemaker generator to be lying within the urinary bladder. Healing was achieved by removing the pacemaker and reutilizing it, after sterilization, in a new pectoral pocket.
