title: Improved focusing for extracorporeal shock wave lithotripsy of ureteral calculi.
abstract: Extracorporeal shock wave lithotripsy of ureteral calculi, which is usually performed with the patient in the prone position, may be difficult or even impossible under certain conditions because x-ray visibility is poor or the calculus is out of range of the shock wave focus. Treatment conditions can be improved by a simple change in the positioning of the patient, using the shock wave head from the contralateral side. This method is applicable for the common Siemens Lithostar device.
