[Computed tomography following extracorporeal shockwave lithotripsy (ESWL) of the kidneys. I: Correlation with acute histopathological findings in experimental animals].
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.
