Evaluation of Routine Urine Analysis in Diagnosing Urinary Tract Infection among Pediatric Population: A Validation Study

Background: Urinary tract infection (UTI) stands out as one of the most common bacterial infections affecting children below the age of five. A valid diagnostic test for UTI is of utmost importance for avoiding bacterial resistance.Objectives: To assess the diagnostic efficacy of routine urine examinations in detecting urinary tract infections in pediatric patients, employing urine culture as the reference standardMaterial and Methods: This diagnostic study was conducted at leady reading hospital, Peshawar. The study employed a non-probability consecutive sampling technique and included 130 children between the ages of 1 and 5 years, regardless of gender, who exhibited symptoms suggestive of urinary tract infections. Exclusion criteria comprised children who had taken antibiotics within the past 48 hours, those with congenital renal anomalies such as renal or renal tumors, renal tract obstruction, and acute renal failure. All participants underwent urine regular examination and urine culture. Sensitivities, specificities, and accuracy were calculated, and the data was further stratified based on gender and age.Results: The mean age of the participants was 2.646±1.32 years. The males were predominant (n-86, 66.2%). The urine examination demonstrated a specificity of 90.91% and a sensitivity of 58.06% in detecting urinary tract infections. A statistically significant difference was observed when comparing the diagnosis of Urinary tract infections using urine culture and urine examination.Conclusion: While urine examinations exhibit satisfactory specificity, their sensitivity is insufficient to be utilized as a reliable diagnostic test for detecting urinary tract infections in children. Clinicians are advised to depend on urine culture for accurate diagnosis in such cases.Keywords: Diagnostic accuracy, Pediatrics, Urine Microbiology, Urinalysis, Urinary tract infection.
