Laser Lithotripsy: Basic Physics
1990Extracorporeal shock-wave (ESWL) lithotripsy is a useful method for fragmentation of stones in the urinary tract. Its application can be extended to gallstone diseases, where it competes with other conventional techniques. A new technology is now emerging which uses a laser and fiber-optic devices for disaggregation of gallstones (Fig. 1).

Laser Lithotripsy: Clinical Applications
1990Since the early 1980s several teams have worked on the problem of fragmenting gallstones by laser [1–6]. The first successful endoscopic-retrograde laser fragmentation of a bile duct stone was reported in 1986 [7]. In the meantime, experiences by other teams in clinical laser lithotripsy of bile duct stones have been published [8–10] or reported on (N.

Techniques of Laser Lithotripsy
Journal of Endourology, 1988A tunable pulsed dye laser has been used for the treatment of 157 patients with renal and ureteral calculi. All calculi treated were too large to be extracted by ureteroscopy or were not appropriate candidates for ESWL. In 106 cases, the stone was completely fragmented with the laser. The laser was used in combination with ESWL in 34 cases.

It seems apparent, from the previous discussion, that no form of intracorporeal lithotripsy represents the perfect treatment modality for all upper urinary-tract calculi. In fact, the role of endoscopic techniques for treatment for upper-tract calculi must be carefully considered given the success of SWL.

[Laser lithotripsy in gastroenterology].
Schweizerische Rundschau fur Medizin Praxis = Revue suisse de medecine Praxis, 1992Almost 90% of all stones in the bile duct can be removed after sphincterotomy and additional mechanical or electrohydraulic lithotripsy. However, a small number of very large or very hard or impacted stones remain, which cannot be removed by conventional endoscopic methods.
