Abstract

Background: Urinary screening program for asymptomatic urinary abnormalities among primary school preventing, halting, and deferring the progression of some diseases. Objectives: To describe the urine examination findings in healthy primary school beginners in Yazd (Iran). Patients and Methods: A complete physical examination in the morning with a midstream urine sample collection obtained from 3014 students in two educational areas of Yazd, Iran. Students with positive test results in the first screening were retested. The urine samples of those with two abnormal results were analyzed using dipstick and microscope concurrently. Results: Children (1527 girls, 1487 boys) were screened and urinary abnormalities were detected in 94 (3.1) subjects at the first screening. Proteinuria was the most common abnormality, detected in 54 (1.79), and next, hematuria was present in 16 subjects. Of these children, 24 (0.79) cases were positive in the second screening. In the third analysis of samples, abnormal findings in the patients included one isolated hematuria, eight isolated proteinuria, and two combined hematuria and proteinuria. 19 out of 3014 (0.63) had a familiar history of renal diseases and three of them had renal disease. Conclusions: Urinary screening can detect chronic renal disease in its earliest stages that may help to prevent the deterioration of future renal function. In addition, a long-term follow-up of the children with hematuria and proteinuria is suggested. © 2015, Shiraz University of Medical Sciences.
