RESUMO
An attempt to compare the value of the excretory urography and renal isotope scanning performed simultaneously in assessing damage in 15 patients with renal trauma has been made. The results obtained as follows: 1) The surgical specimens in seven cases showed more marked in severity of the parenchymal injury than the excretory urography did. 2) In 11 cases with moderate or severe injury, renal isotope scanning was more accurate in delineating the damaged area than the excretory urography, while in four cases with minimal injury, both were roughly equal in accuracy. 3) Because of the case, safety and accuracy of the renal isotope scanning, its use is recommendable in patients with renal trauma as a procedure for follow-up study and in those with allergic tendency or iodine hypersensitivity.
