Hallazgos gammagráficos en ni？os con primera infección febril del tracto urinario

introduction. urinary tract infection (uti) is one of the more frequent bacterial infections in childhood. the aim of present research was to know the acute phase renal alterations of the first febrile infection of urinary tract. methods. ninety children with a microbiological diagnosis of first febrile infection of urinary tract were studied and a renal tc dmsa scintigraphy was done in the acute phase of infection. scintigraphy results were correlated with the fever length and intensity before diagnosis, acute phase reactants (hemogram, erythrosedimentation and c reactive protein (crp) and the radiological studies results (renal us and urination urethrocystography). results. there was a female sex predominance and the 84,4% of patients were under 1 year. the 59% of patients had scintigraphy alterations and the radiodrug hypocaptation pattern was the predominant finding in the 75,5% of them. there was not a significant association between the fever length and intensity and the renal alterations. from the laboratory parameters only the rcp was statistically significant with renal alterations and the radiologic findings detected by renal us and urination urethrocystography had not statistic correlation with the renal affection detected by renal scintigraphy. conclusions. a high percentage of patients had an extensive infection to renal parenchyma and the crp was the only guiding parameter of renal damage.
