Intracorporeal lithotripters are available in nearly all urological institutions. The authors compared the CALCUTRIPT made by K. Storz Co. and the Swiss LITHOCLAST in in vitro studies. No major difference in the efficacy of disintegration was observed after subjecting chalk cubes to the two modalities. Human tissue of the renal pelvis, ureter and bladder was exposed to both energy-sources. In the case of the electrohydraulic shock wave the authors found complete rupture of all three layers of the ureteric wall after exposure even with low energy, while tissue perforation was observed in only one of 72 tissue samples exposed to the LITHOCLAST. The authors recommend the LITHOCLAST because of its minimal invasiveness for the treatment of calculi especially in the ureter.
几乎所有的泌尿外科机构都配备了体内碎石机。作者在体外研究中比较了K. Storz公司生产的CALCUTRIPT和瑞士的LITHOCLAST。在用这两种方式处理白垩立方体后，未观察到碎石效果有重大差异。肾盂、输尿管和膀胱的人体组织都暴露于这两种能量源下。对于电液压冲击波，作者发现即使使用低能量，输尿管壁的所有三层在暴露后都会完全破裂，而在72个暴露于LITHOCLAST的组织样本中，仅观察到一例组织穿孔。由于LITHOCLAST对结石治疗的侵入性最小，尤其是对输尿管结石的治疗，作者推荐使用LITHOCLAST。
