ROLE OF BACTERIURIA AND PYURIA IN URINARY TRACT INFECTION OF SELECTED SUBJECTS OF TAMILNADU, SOUTH INDIA

BIO CHEMISTRY - HEALTH SCIENCES

Urinary tract infection is not much complicated which occurs commonly in both the genders . It is caused by the uropathogenic bacteria, usually Escherichia coli, enters into the urinary tract via bladder and defeats the immunity. Analyzing the presence of microorganisms in the urinary tract, compares bacteriuria or urinary tract infections (UTI), this study was conducted to assess the values for bacteriuria and pyuria and evaluate to go for the treatment. A total of 500 urine samples recorded data were obtained which were analysed by simple randomized method from the laboratory of the Govt. hospital Nagapattinam, Tamilnadu. Urine cultured values were compared with normal urine microscopy profiles of positive and negative predictive values of the findings of urine analysed datas were segregated. 350 (70%) of the cases were females. 55.7 % (159/500) of patients had positive urine cultures. The most prevalent cultured micro-organism was E. coli (61.2 %). Sensitivity, specificity, positive and negative predictive values of microscopic pyuria was 84%, 85%, 48%, 95 %, respectively. As the same for bacteriuria, these calculations were 80%, 97%, 93%, 94% and for the category with both bacteriuria and pyuria were 82%, 99%, 95%, 97%, respectively. According to the results, it is concluded that the urine microscopy features seems to be useful to exclude the presence of infection if the results of both bacteriuria and pyuria are negative, but positive test results have to be confirmed.
