123 patients underwent 320 extracorporeal shock wave lithotripsy (ESWL) sessions with the Wolf 'Piezolith 2200' lithotripter. The overall success rate, judged by adequate stone fragmentation into particles of 2 mm or less as seen on X-ray, was 92%. Few complications occurred. The lithotripter was easy to operate, and treatment was painless.
