Renal scintigraphy using technetium dimercaptosuccinic acid in the diagnosis of pyelonephritis in children: study of 17 cases. J. Pediatr. (Rio J.) [online]. 2001, vol.77, n.2, pp. 119-123.

OBJECTIVE: to determine whether the presence of abnormal results in DMSA renal scintigraphy indicates pyelonephritis. METHODS: we performed the washout test in 17 children with urinary tract infection, as a criterion standard, to locate the infection site. All the children underwent DMSA renal scintigraphy in the acute phase of the disease. The results were analyzed by the chi-square test or Fisher test. RESULTS: DMSA renal scintigraphy revealed changes in all five cases of pyelonephritis, suggesting acute kidney involvement. On the other hand, only one child with cystitis (total = 12 cases) had abnormal results in renal scintigraphy. Sensitivity and specificity were 100% and 92%, respectively. CONCLUSION: DMSA renal scintigraphy is a sensitive method for the diagnosis of pyelonephritis in children.
