Abstract | BACKGROUND: METHODS: Sixty-four children with a first episode of APN underwent a 99mTc-DMSA scan. If there were abnormal findings on this scan, another scan was performed 6 and 12 months later. RESULTS: The baseline 99mTc-DMSA scan showed cortical changes in 35 patients (54.7 %). One the 6- and 12-month follow-up scans, 25 patients (39.06 %) and 21 patients (32.8 %), respectively, had cortical lesions. In multiple logistic regressions with the final 99mTc-DMSA scan results as the dependent variable, only the age range of the patients (β = 1.062; 95 % CI 1.014-1.113; p = 0.01) showed an independent and significant association. Gender, therapeutic delay time, ultrasonography, and voiding cystourethrogram results, as well as laboratory test results including the erythrocyte sedimentation rate, C-reactive protein level, white blood cell counts, and type of bacteria in the urine, did not show such an association (p > 0.05). CONCLUSION: There is not a significant difference between the results of 6- and 12-month 99mTc-DMSA follow-up scans. A follow-up 99mTc-DMSA scan should be performed 12 months after the acute scan to yield a more accurate diagnosis of permanent renal damage. If present, long-term follow-up of patients is necessary.
