[A case of stone former with pacemaker treated by extracorporeal shock wave lithotripsy]

A stone former, a 60-year-old male with a pacemaker, was treated by extracorporeal shock wave lithotripsy (ESWL). He had been on a DVI pacemaker due to sick sinus syndrome since the age of 52. During treatment for left ureteral stone by ESWL, the pacemaker was stopped, since there was a possibility of extra systoles caused by coupled triggering of the shock wave with the pacemaker spike wave in ECG. Pulse and blood pressure were maintained by continuous drip infusion of phenylephrine chloride and isoproterenol. As a result, ESWL was accomplished and pacemaking was reestablished without any problem. KUB revealed that the patient became stone free on the postoperative 17th day.
