Diagnostic value of full urine test for kidney and urinary tract injury in patients with blunt trauma compared to CT scan findings

Introduction: Blunt trauma is one of the common causes of damage to the kidney and urinary tract. Timely and accurate diagnosis of these injuries is critical for effective management. Complete urine tests and CT scans are two important diagnostic methods in this field. This study examines the diagnostic value of complete urinalysis and its comparison with CT scan in the diagnosis of kidney and urinary tract injuries in patients with blunt trauma. Materials and methods: This study was conducted in a cross-sectional analytical manner, the study population included patients with blunt abdominal trauma referred to Shahid Beheshti Hospital in Qom. All CT scans that reported a lack of enhancement or weak contrast of kidney parenchyma and urinary tracts or kidney navel hematoma were considered positive. All CT scans interpreted by a radiologist were included in the study. The data checklist also recorded the findings of the urinalysis in terms of hematuria. Finally, the sensitivity and specificity of hematuria were compared with CT scan findings in diagnosing kidney and urinary tract injuries. Results: The results showed that the sensitivity, specificity, positive and negative predictive value in microscopic hematuria were 97.6%, 50.8%, 35.04%, and 99.1%, respectively. Conclusion: CT scan is the main and most reliable tool in diagnosing kidney and urinary tract injuries caused by blunt trauma. Complete urinalysis can be used as an initial and complementary evaluation method in the diagnostic process, but should not be used alone for clinical decisions. Further research is necessary to improve this field's diagnostic methods and data processing.
