To evaluate the degree of ischemic formation at the tissue level after high-energy shock wave (HESW) application in a time- and dose-dependent manner, an experimental study in rabbits was performed. Following varying numbers of HESWs (1,000–2,000–3,000 shock waves) under fluoroscopic localization, treated kidneys were removed, by assessing tissue concentrations of two different free-radical scavenger enzymes (superoxide dismutase and catalase) the degree of formation of free oxygen radicals (i.e. ischemia) was evaluated. Evaluation of our results showed a statistically significant (p < 0.05) decrease in tissue scavenger enzyme levels (i.e. formation of free oxygen radicals) after 24 h following HESW application. However, results obtained 7 days after ESWL demonstrated disappearance of ischemia with normalization of tissue enzyme levels (p > 0.05)
