The side effects of high-energy shockwaves (HESW) from two different sources on kidney parenchyma obtained from 10 patients treated by radical nephrectomy for renal cell carcinoma were examined. Immediately after nephrectomy, the kidneys were perfused with cold HTK solution and kept in hypothermia (8 degrees C) for a maximum of 4 hours. In five cases, the tumor-free parenchyma was treated at the upper or lower renal pole with 2000 shocks, energy output 21 kV, in an experimental electromagnetic shockwave system (Siemens Co., Erlangen). In the other five cases, the upper or lower poles were treated with 2000 shocks, energy output 24 kV, in an electrohydraulic spark gap system (MFL 5000; Dornier Medizintechnik, Germering). The resulting tissue defects were analyzed by histologic examinations. Changes after treatment with the electromagnetic system were found mainly in the tubules and midsized blood vessels in a well-defined focal area. Treatment with the electrohydraulic system was followed by tubular and glomerular lesions combined with vessel defects in a patchy pattern. The model is able to define the side effects of HESW in the human kidney and to test the side effects of different lithotripters.
