AI Summary & Key Takeaways
AI InsightWhen the relationship of CUA, which is required for the preliminary diagnosis of UTI, with the growth rates in urine culture, it was found that the highest growth rate was in those with Nitrite(+), but false negativity was also high.

Abstract
In this study, relationship of complete urinalysis (CUA) with urinary culture growth rates in infants admitted with a preliminary diagnosis of urinary tract infection (UTI) was examined. The files of 101 infants admitted with a preliminary diagnosis of UTI were reviewed retrospectively. Units used for the preliminary diagnosis of UTI; at CUA; Leukocyte>5, Leukocyte Esterase(LE) positivity, Nitrite Positivity, LE + Nitrite positivity were compared with the growth rate in urine culture. CUA samples were taken with sterile bags. Urine cultures were taken with a catheter from those with significant findings in CUA. While the rate of growth in urine culture was 67.4% in those with Leukocytes>5 in CUA, the rate of growth was 57.1% when Leukocytes were<5. While the rate of growth in urine culture was 76.1% in those with LE(+), it was 12.5% in those with LE(-). While the rate of growth in urine culture was 94.4% in those with nitrite(+), it was 44.7% in those with nitrite(-). While the growth rate in urine culture was 73.3% in those with LE(+)+Nitrite(+), it was 21.1% in those with LE(-)+Nitrite(-). When the relationship of CUA, which is required for the preliminary diagnosis of UTI, with the growth rates in urine culture, it was found that the highest growth rate was in those with Nitrite(+), but false negativity was also high. It is thought that the detection of LE(+) with the lowest false-negative rate in the reproduction of the urine culture is more reliable in diagnosing UTI.
