Abstract
Electro-impulse intracorporeal lithotripsy comprises bringing electrodes of a probe in immediate electrical contact with the calculus and supplying to the electrodes of very short high voltage impulses capable to ignite electrical spark discharge and establish a discharge channel within the bulk of the calculus. The channel goes through the calculus and creates tensile stresses, destroying the calculus.
