In our article, we reported on 645 renal abnormalities found in 132 686 school children screened through the use of renal ultrasonography. Of those with renal abnormalities, 50 patients had surgically correctable lesions. The other 595 cases have been examined fully to establish the correct diagnosis and the prevalence of renal abnormalities in school children. However, in this study, the cost to benefit ratio was determined by total expense to number of surgically treatable diseases.
