Abstract:
BACKGROUND: Since 1998, mass urinary screening tests have been conducted in Korean school children. We analyzed the urinary screening test data gathered from the metropolitan city, Seoul, to identify the prevalence of persistent urine abnormalities. METHODS: The students were tested for hematuria and/or proteinuria using dipstick urinalysis. If the results were positive, the students were asked to visit a medical clinic to recheck urinalysis and in report their results. RESULTS: Among 1,337,210 students, who were screened with initial urinalysis, 10,871 students (proteinuria, 3,626 (0.27%); hematuria, 7,634 (0.57%); both, 389) were recommended to undergo second urinalysis in which 8,819 students (81.1%) did. Among them, 851 had persistent proteinuria and 2,618 had persistent hematuria. The results of the first urinalysis were scored based on the severity of hematuria and proteinuria from +1 to +4. Among all students 24.7% of the students who scored +1 and 40.4% who scored +3 proteinuria on the first test had persistent proteinuria, and 56.4% with both proteinuria and hematuria had persistent proteinuria on the second test. For hematuria, the more positive in the first test showed more prevalence of persistent hematuria. And 61.6% of students with both proteinuria and hematuia had persistent hematuria on the second test. CONCLUSION: The presence of both hematuria and proteinuria seemed to be a powerful predictor for persistent abnormal urine finding. And the more positive response in the first test was related to persistent abnormal finding. Therefore we should follow up closely for those students with positive findings.
