title: [Effects of focused shock waves on children's kidney: experimental study].
abstract: The effects of focused shock waves produced by URAT-P2 unit on renal tissue was studied in 120 immature rats with 100-120 g b.w. Morphological material obtained after the procedure and 3 months after it was studied with reference to the following parameters of the impact: interelectrode spacing, capacitor capacitance, capacitor charging voltage, pressure in the therapeutic focus, number of impulses. It was found that one of the essential damaging factors of the shock waves is spontaneous widening of the interelectrode spacing in the course of the fragmentation which entails an increase in the pressure amplitude in the center of the therapeutic focus with resultant prolongation of the impulse.
