The authors discuss the results ultrasonographic (USG), power Doppler (PD) and thermovision (TV) examination in monitoring changes of kidney parenchyma in 30 children with nephrolithiasis after ESWL treatment. To monitor possible effect of shock wave on the kidney parenchyma the USG, PD and TV examination were done before ESWL treatment as well as, 48 hours and 3 months following the treatment. Parts of kidney parenchyma localized on the way of shock wave to the stone were analysed. Echogenicity of kidney parenchyma was analysed by comparison of echo amplitude in subsequent USG examinations. Parenchymal blood flow by computer analyse was estimated. In TV examination the temperature distribution in the place of skin kidney projection was estimated. Changes in echogenicity of kidney parenchyma and impaired kidney parenchymal blood flow 48 hours after ESWL were found. In TV examination 48 hours after ESWL transient reduction in skin temperature was observed in the place of shock wave transmission. In 3 months after ESWL disturbances in the kidney parenchyma in USG, PD and TV were not observed.
