Analysis Of Urine Screening And Clinical Significance Of Primary And Secondary School Students In Lanzhou City

Objective To know about the urinary anomalies among the primary and middle school students in Lanzhou city and chronic kidney disease in the region, to prevent the occurrence of early kidney disease, and to provide evidence for the further improvement of people’s cognition of kidney disease in poor areas.Methods To test the morning urine with the urine dipstick, from April, 2012 to October, 2013, according to the particularity of Lanzhou city in geographical location, there were 10,800 primary and middle school students from two boroughs and one county selected randomly in groups as the objects of screening. Those experimenters whose result of initial urine tests is positive need to be tested for the second time two weeks later. The results were categorized into four types(occult blood positive, protoplasmic, occult blood + protoplasmic, white blood cells urine). The experimenters whose results are positive twice are qualified for regular urine examination in local secondary-level hospitals.Results As a result, of all the student experimenters in Lanzhou, it was found that there were 1655(15.31%) with urine occult blood, 517(4.78%) with positive urine protein, 113(1.04%) with occult blood with protein, 744(6.88%) with white blood cells. Two weeks later, the second test showed that 814(7.55%) were with occult blood positive, 231(2.13%) with positive urine protein, 75(0.69%) with occult blood with protein, 271(2.51%) with white blood cells. 456 experimenters from 1391 received the regular urine examination and the result showed that there were 32 cases with white blood cells, 147 cases with hematuria, 23 cases with albuminuria, 13 cases of proteinuria with blood in the urine. Hematuria and proteinuria in junior middle school students is higher than primary school students(P < 0.05), and the rate of hematite, white blood cells urine being positive among primary school students is high. It was found that there were 12 cases of chronic kidney disease with the abnormal urine examination.Conclusions 1.Those asymptomatic children with abnormal urine test could be found in urine screening at school. If the children were provided a chance of an early intervention, the severity of chronic kidney disease(CKD) might be reduced and also the occurrence of the end-stage renal failure might be relayed.2. As for the screening for primary and middle school students, choose a better test method according to the actual situation and select the urine positive results of those primary and middle school students with the test. Then eliminate the rate of false positive according to the result of urine routine effectively, and do well in the later follow-up work.3. To strengthen the urine screening for children in poverty-stricken areas and the follow-up work, promote the knowledge of the kidney disease to parents and raise their cognition of it.
