ABSTRACT
PURPOSE: This study was performed to elucidate the clinical pictures of acute focal bacterial nephritis(nephronia) in children. METHODS: We reviewed 9 children with nephronia diagnosed by ultrasonography or computed tomography of kidneys from September 1994 to August 2004. RESULTS: The overall male to female ratio was 2:1, and the age distribution ranged from 0.1 to 6 years(mean 2.8+/-2.2). The cardinal symptoms were fever, chills, abdominal pain and dysuria/frequency. The initial leukocyte count was 21,000+/-5,600/uL; ESR, 60+/-23 mm/hr; CRP, 17+/-10 mg/dl. Pyuria was noted in every patient and persisted for 10.5+/-7.8 days after antimicrobial treatment. Abdominal sonography demonstrated focal lesion of ill-defined margin and low echogenicity in 5 of 9 patients(55.6%), while computed tomography revealed nonenhancing low density area in all patients(100%). Three of 9 patients(33.3%) had vesicoureteral reflux, greater than grade III. The initial (99m)Tc-DMSA scan showed one or multiple cortical defects in every patient, and improvements were noted in 2(33.3%) of 6 patients who received follow up scan after 4 months. Intravenous antibiotics was given in every patient under admission. Total febrile period was 11.8+/-6.3 days(pre-admission, 4.0+/-3.0; post-admission, 7.8+/-5.5 days) and the patients needed hospitalization for 17.2+/-8.1 days. CONCLUSION: For the early diagnosis of 'acute focal bacterial nephritis' we should perform renal computed tomography first rather than ultrasonography, when the child has toxic symptoms and severe inflammatory responses in blood and urine.
