[Computed tomography after extracorporeal shockwave lithotripsy (ESWL) of the kidneys. II. A correlation with the histopathologic findings 3 weeks later in an animal experiment].
In a pig model, 13 kidneys were treated with a second generation lithotripter and examined by CT immediately and three weeks after ESWL. 9 (69%) acute traumatic lesions were seen in CT without, and 10 (77%) in CT with contrast in the 13 treated kidneys. After 3 weeks only 1 residual lesion persisted in CT contrast studies. On the histopathologic specimens residuals of bleeding were found in 3 (23%) of the 13 kidneys treated, which could not be seen in CT studies. CT is accurate in monitoring acute traumatic renal lesions after ESWL, but appears less reliable in chronic ones. Three weeks after ESWL traumatic renal lesions show marked regression.
