[Administration of intracorporeal, laser-induced shock waves for the destruction of urinary calculi].

In spite of rapid developments in modern endourologic methods of urinary tract stone management, a definitive solution regarding the energy source for intracorporeal lithotripsy has not yet been found. Laser-induced shock wave lithotripsy is one of the most promising approaches. The evolution of this treatment modality within the last 4 years gives rise to the hope that a commonly accepted standard method will soon become available. General acceptance depends on increasing reliability and effectivity of current systems, especially in the case of problem stones. The advantages of intracorporeal shock wave lithotripsy can be summarized in the following points. (1) The shock wave is applied directly to the intended object, i.e., the stone, so that adverse side effects are virtually excluded. (2) Laser-induced shock wave lithotripsy leads to a precise and extremely fine fragmentation of stones, avoiding urinary tract obstruction with consecutive tract infection. (3) Cost and treatment handling are further points in favour of intracorporeal lithotripsy. (4) Perspectives are widened by the possibility of treating, of biliary, pancreatic and salivary gland duct stones.
