Abstract:
The authors subjected to the effects of a shock wave 20 concrements of the biliary pathways. Their size varied but was within the range of 8-30 mm. Their chemical composition and crystalline pattern from which ensues the hardness of the concrement was verified by the method of X-ray diffraction. It was confirmed that the apparatus MEDILIT 5 which uses discharges of electric sparks between two electrodes deposited under water is able to destroy concrements of the biliary pathways to a maximum size of 3 mm. This effect is independent on the chemical composition of the concrements, their hardness and size up to a diameter of 30 mm.
