Abstract:

Objective To investigate the characteristics of screening data of urinalysis in school students in Yangzhou, thus providing basic data for abnormal urinalysis data in the local area and offering standardized management and follow-up. Methods In 2021, a total of 1973 school students aged 6-14 years old in Yangzhou were selected for urinalysis using a urine analyzer. Those with abnormal findings were re-examined for urinalysis and urinary sediment. Screening data of urinalysis and re-examined data were analyzed. Results Screening data showed that the positive rate of urinary occult blood was 9.22%, and the positive rate of re-examined hematuria was 0.61%. The positive rate of urinary protein in the initial examination and re-examination was 6.08%, and 0.76%, respectively. The positive rate of urinary leukocyte esterase was 5.58%, and that of leukocytosis in the re-examination was 1.93%. There were a few other abnormalities detected in the urinalysis. Conclusion The most common abnormal urinalysis findings in primary and middle school students in Yangzhou is occult blood, and a small amount of proteinuria. Urinary tract infection is mostly found in female children. Screening of urinalysis contributes to identify children with asymptomatic abnormalities in urinalysis, thus providing early interventions.
