The aim of this study is to determine the specifity and sensitivity of the procedures used in determining bacteriuria and pyuria regarding the urine culture results. In the Central Microbiology Laboratory of Gazi University Hospital midstream urine samples of 161 patients with pre-diagnosis of urinary tract infections were used in this study. They were cultured using standard procedures. Bacteriuria and pyuria were evaluated with microscopic examination. Combur 10 Test M kits were used for leukocyte esterase (LE) and nitrite tests. In 24 (%14.9) of the cases growth was observed, in one case contamination was determined and in 136 (%84.5) of the cases no growth was observed. The sensitivity and specifity of the combination of LE and nitrite tests were 72.2% and 97.5%, respectively, while the sensitivity and specifity of the combination of determining pyuria was %95 and bacteriuria which is determined by Gram stain method was %95. It was observed that in the diagnosis of urinary tract infections, the microscopic examination of urine was more specific and sensitive than examining the urine by dipsticks. As a result, although using dipsticks are easier and simpler than microscopic examination, it is better to use microscopic examination in order to choose the correct treatment in patient groups for whom empirical treatment is intended.
