In an experimental study on pigs, 28 stone-free kidneys were treated with a second generation lithotripter. Histologically, acute bleeding was seen after ESWL in 23 (82%) of the 28 treated kidneys. CT studies before and after contrast were correct in 20/28 (74%) cases. It was shown that extracorporeal shock waves cause renal bleeding that is only partially detected by computed tomography. It can be concluded that the CT findings seen in a high percentage of renal stone patients after ESWL represent bleeding. The incidence of renal bleeding after ESWL and thus the possible risk of hypertension has obviously been underestimated so far in clinical studies.
在一项对猪的实验研究中，用第二代碎石机对28个无结石的肾脏进行了治疗。组织学检查显示，28个接受治疗的肾脏中有23个（82%）在体外冲击波碎石术（ESWL）后出现急性出血。增强CT检查前后诊断正确的有20/28（74%）例。结果表明，体外冲击波会导致肾脏出血，而计算机断层扫描只能部分检测到这种出血。可以得出结论，在ESWL后高比例肾结石患者中观察到的CT表现代表出血。到目前为止，临床研究显然低估了ESWL后肾脏出血的发生率以及由此可能产生的高血压风险。
