title: [Renal scintigraphy with Tc99m DMSA (dimercaptosuccinic acid) in acute pyelonephritis].
abstract: Twenty patients, 6 months to 11 year old, with clinically recognized acute pyelonephritis, were evaluated with Tc99m DMSA renal scintigraphy in the first 15 days of their illness to validate this method in the detection of the acute renal inflammatory disease. In 85% of Tc99m DMSA scintigraphies some kind of abnormality (focal or diffuse, unilateral or bilateral) was observed. Second renal images obtained at an average 8.5 months later, showed total disappearance of abnormal findings in 42%; partial regression in 50% and no changes in 8% of these cases. Tc99m DMSA scintigraphy seems to be a good diagnostic tool to confirm acute renal compromise in urinary tract infections. Besides follow up examinations, at least three months later with this same method, were able to confirm sustained renal lesions.
