ABSTRACT |
PURPOSE: Acute pyelonephritis is one of the most common causes of unexplained fever in children. It may lead to the development of progressive renal damage. However, the detection of acute pyelonephritis can be difficult, especially in infants. The objective of this study was to evaluate the diagnostic value of various lab tests and imaging studies for acute renal parenchymal changes in children with APN. We correlated the clinical and laboratory manifestations of acute pyelonephritis with the imaging studies. METHODS: We reviewed the records of 115 children (85 males and 30 females) who were hospitalized during the period of January 1998 to December 2002 with initial clinical symptoms suggestive of pyelonephritis. The patients' age, sex, duration of fever, laboratory findings, and causative organisms were compared with the findings of imaging studies (Technetium-99m dimercaptosuccinic acid renal scan, renal ultrasonography, intravenous pyelography, voiding cystourethrography). RESULTS: No significant relation between the number of febrile days, leukocyte count, causative organism, and the renal abnormalities in the imaging studies were observed. On the other hand, both C-reactive protein and erythrocyte sedimentation rate levels were significantly elevated in children with positive dimercaptosuccinic acid renal scan. Furthermore, females and children older than 1 year presented with significantly higher rate of abnormal dimercaptosuccinic acid renal scan findings and vesicoureteral reflux presented by voiding cystourethrography. CONCLUSION: We recommend females and children older than 1 year who are suspected of acute pyelonephritis be evaluated carefully for renal involvement by performing imaging studies including dimercaptosuccinic acid renal scan and voiding cystourethrography. |
