Treatment of pacemaker patients with extracorporeal shock wave lithotripsy: experience from 2 continents

Patients with cardiac pacemakers currently are treated by extracorporeal shock wave lithotripsy only by agreement between individual physicians and patients. We present the results of a survey of patterns of extracorporeal shock wave lithotripsy treatment (or nontreatment) of patients with pacemakers in the United States and Europe. Letters of inquiry regarding treatment of pacemaker patients were sent to 141 United States extracorporeal shock wave lithotripsy sites and 55 sites in Europe. Responses were received from 81 (57%) and 17 (31%) sites, respectively. A total of 131 patients received 142 treatments and pacemaker-related complications occurred in 4 (none was lethal, 3 were minor and all were corrected immediately). No patient required replacement of the pacemaker. No correlation existed between complications and pacemaker type or manufacturer. Urologists who treat patients with a pacemaker required previous clearance of the patients by the cardiologist, a cardiologist in or near the extracorporeal shock wave lithotripsy suite and standby of corrective equipment or temporary pacemakers.
