Hubungan antara Pemeriksaan Nitrit Urine dan Bacterial Scattergram Automated Urine Analyzer dengan Kultur Urine pada pasien Infeksi Saluran Kemih di Rs Adam Malik

Abstract

Introduction Urinary tract infection is a common urinary tract disease that is often caused by bacteria. Bacterial scattergram is a parameter of automated urinalysis that is able to provide information on the number of bacteria and an estimate of the type of Grampositive or Gram-negative bacteria. Objective To determination correlation of Urine Nitrite Examination and Bacterial Scattergram Automated Urine Analyzer with Urine Culture in Urinary Tract Infection Patients at Adam Malik Hospital. Methods This study is a retrospective cross-sectional study. The study subjects were 91 subjects with a diagnosis of UTI at Adam Malik Hospital in 2024. Urinalysis and urine culture data were taken to be analyzed using Pearson correlation test statistics and Spearman rank test. All statistical tests with a p value <0.05 were considered significant. Results The subjects were 46 males (50.5%) and 45 females (49.5%). The mean age of the subjects was 55 years. The most common type of urine sample was midstream urine (63.7%). Positive urine nitrite was found in 24 (26.4%) urinalysis results. The most common bacteria causing UTI was E. coli: 22 (24,2%). From the scattergram examination, 60 subjects (65.9%) showed angles <30º and 19 subjects (20.9%) formed angles >30º, and unclassified angles were 12 subjects (13.2%). Conclusion There is a significant relationship between urine nitrite examination and the types of bacteria that grow on urine culture (p=0.008). There is a significant relationship between urine bacterial scattergram examination and the types of bacteria that grow on urine culture (p<0.001)
