Abstract
This cross section study was carried out in Assiut governorate, upper Egypt. from February 2009 to October 2009. 1300 healthy students were included in this study, 637(49%) boys and 663(51%) girls.The age of the students ranged from 7 to 15 years. Urinary screening was performed with the dipstick test for protein, blood, glucose, nitrite and leukocyte. Students with abnormal urinary findings re-examined again after 2 weeks by dipstick test. Students with persistent abnormal urinary findings were further subjected to general examination (blood pressure, weight and height), local abdominal examination, complete urine examination, urine culture, serum creatinine, and abdominal ultrasound.
Results: 176 students (13.54%) had urinary abnormalities in the first screening. 37 students (2.85%) had persistent urinary abnormalities in the second test, isolated hematuria was found in 32 students (2.46%), combined hematuria and proteinuria in one student (0.08%), glucosuria in 3 students (0.23%), nitrite in one student (0.08%), and none had isolated proteinuria. Only 30 students (2.3%) had urinary abnormalities in complete urine examination. Among them 22 students (1.69%) had isolated hematuria, one student (0.08%) had combined hematuria and proteinuria, 13 students (1%) had pyuria, 2 students (0.15 %) had glucosuria, 20 students (1.54 %) had crystaluria.
Four students (0.3%) had systolic hypertension, and 7 students (0.54%) had diastolic hypertension. Six students (0.46 %) were under weight, and 6 students (0.46 %) had short stature. Serum creatinine and abdominal ultrasound were normal in all studied students. There was no significant difference observed in the prevalence of urinary abnormalities between boys and girls (P value = 0.09), but the prevalence was higher in older students
(P value = 0.001).
Conclusion: asymptomatic urinary abnormalities might be detected by the school screening program, a way for early management. Follow up of patients with confirmed abnormal urine examination, as some of these diseases may be reversible, recurrent or progressive.
