Evaluation of urine analysis in adults with simple and complicated appendicitis

Abstract

INTRODUCTION: Acute appendicitis is one of the common abdominal emergencies. We aimed in this study to evaluate whether routine urinalysis may use in discriminating between simple appendicitis and complicated appendicitis in the emergency department.Acute appendicitis is one of the common abdominal emergencies.

We aimed in this study to evaluate whether routine urinalysis may use in discriminating between simple appendicitis and complicated appendicitis in the emergency department. METHODS: Patients over 18 years of age with a pathological diagnosis of acute appendicitis and those who underwent urine analysis in the emergency department were included in the study. Patients with missing data were excluded. According to pathology reports, patients were classified as simple and complicated appendicitis. RESULTS: Compared to simple appendicitis, the complicated appendicitis group had significantly higher urine ketone body, protein, and nitrite counts on admission (p<0.05 for all parameters). Urine ketone bodies and positive urine nitrite were found to predict statistically significant complicated appendicitis in multivariate logistic regression analysis (for all values p<0.001). DISCUSSION AND CONCLUSION: Urine analysis is one of the routine tests performed in patients with suspected acute abdomen. Therefore, we think that especially urine ketone bodies and positive urine nitrite in urine analysis may be a warning for complicated appendicitis.
