fast and abnormal urinalysis: the effective screening tools in pediatric abdominal trauma

Objective: the present study examines the diagnostic accuracy of abdominal ultrasonography and urinalysis test in children with blunt abdominal trauma, compared with ct scan. the aim of this study was to compare the diagnostic value of ultrasound and urinalysis test with ct scan as a golden standard diagnostic method in predicting abdominal peritoneal injury in these patients. methods: this prospective study, based on diagnostic accuracy evaluation, was performed on children with blunt abdominal traumas less than 12 years of age who were referred to the emergency department from 2017-2018 and for whom abdominal ultrasonography, urinalysis and abdominal ct scans were requested. demographic data, mechanism of trauma, the results of urine tests, ultrasound and ct scan of the abdomen were recorded. sensitivity, specificity, positive and negative predictive values were used to measure the diagnostic power of the tests. results: in this study, 100 children with multiple traumas were included. the mean age of these patients was 5.75 ± 3 years with a range of 1-12 years. in terms of sexual distribution, 69 (69%) were boys and 31 (31%) were girls. according to the results, ultrasound with an abnormal urinalysis test had sensitivity of 85.7%, specificity of 91.9%, positive predictive value of 63.2% and negative predictive value of 97.5%. the accuracy was 91%. conclusion: according to the results of this study, the combination of ultrasonography and urinalysis resulted in a significant increase in diagnostic value (p <0.001). pediatric patients with a negative ultrasonography and urinalysis test should be observed rather than subjected to the radiation risk of ct.
