We used the data from a school urine screening program conducted in Yonago, Tottori Prefecture, Japan, to investigate the prevalence of urinary abnormalities, final diagnoses, renal histologic diagnoses and prognoses of cases in which renal biopsy was performed. We also performed renal biopsies and assessed the renal histologic diagnoses and prognoses of cases identified by clinical symptoms. Between 1978 and 2016, 418,802 children were screened; of them, 2,567 underwent a tertiary examination. The number of children received a final diagnosis was decreased from a cumulative total of 84.2 per 10,000 persons to 4.50 before and after setting up of the judging committee of a school urine screening program, and the “normal” in a final diagnosis was reduced. Moreover, the “glomerulonephritis” in that fell from 3.1 to 0.76. We performed renal biopsy for 54 cases identified by a school urine screening program and 39 cases identified by clinical symptoms. The most common histological diagnoses were IgA nephropathy in cases found by the school urine screening program and purpura nephritis in cases identified by clinical symptoms. The judging committee of a school urine screening program in Yonago city contributed to an accuracy improvement of a school urine screening program.
