Abstract

The Wolf Piezolith 2200 lithotripter utilizes piezoceramic shock wave induction and ultrasound localization; it is mobile and requires no room adaption. Because of the low pressure intensity at the skin level, extracorporeal shock wave lithotripsy (ESWL) is pain free, and no analgesia is needed during treatment. In August 1986 a prototype of the Wolf lithotripter (Richard Wolf Company) became operational at the Department of Urology, Rudolfstiftung, Vienna, and was replaced by the Piezolith 2200 in February 1987, and that machine, in turn, was exchanged in February against the advanced model Piezolith 2300 with a dual scanning system. This presentation updates a previous report on our experience with piezo-ESWL1 and presents results of our first treatments on the biliary system.

In all, 914 units were treated, including renal stones (641), ureteral stones (187), and biliary stones (16 in bile duct, 6 in gallbladder). Treatment proved to be essentially pain free; general anesthesia was used only in children under 3 years old. Ultrasound localization was highly reliable for renal stones. Calculi in the ureter generally can be visualized only in the most distal and most proximal portions. The problems in passing stone debris were comparable to other lithotripters.
