✦ Synopsis

With a high intensity Q-switched Nd-YAG laser shock waves can be generated in a liquid close to the calculus. Up to 80 mJ single pulse energy with 8 nsec pulse duration can be transmitted through flexible quartz fibers. Energy conversion and enhancement can be accomplished at the fiber tip with optical focussing of the light at the quartz tip, with irrigation solutions and with high pulse energies. Iron-III-dextran solutions (1 mg Fe3+/1) and magnesium chloride (50 mmol/l) increased the pressure in the laser induced breakdown up to ten times (8,000-10,000 bar). Smaller stone particles and higher efficacy in stone fragmentation could be achieved.

To date, there are two fairly well-established alternatives for laserinduced shock-wave lithotripsy in clinical practice. The Q-switched Nd:YAG laser is distinguished by the high-stone selectivity of its coupler systems. The necessity of a coupler system and its fairly small conversion rate of light

## Background and Objective : Several laser procedures, extracorporeal lithotripsies (ESWL), and high-velocity missile trauma generate pressure transients that are transmitted through the tissues. Despite several publications demonstrating shock wave-induced tissue injury, little is known about its

Gallstone ileus is caused by a gallstone impacted in the intestinal lumen. Usually the gallstone enters the bowel through a cholecystoduodenal fistula and travels a varying length aborally before stopping. This situation often requires an emergency laparotomy. A case is presented where the gallstone

The extraction of large gallstones in laparoscopic cholecystectomy either requires the enlargement of one of the incisions or intraoperative lithotripsy. Preoperative extracorporeal shock-wave lithotripsy (ESWL) might theoretically solve the problem and facilitate the extraction of the gallbladder.
