Abstract
To evaluate the accuracy of diagnosing urinary tract infections using a new, recently described, standardized clean-catch collection technique. Cross-sectional study of infants <90 days old admitted due to fever without a source, with two matched samples of urine obtained using two different methods: clean-catch standardized stimulation technique and bladder catheterization. Sixty paired urine cultures were obtained. The median age was 44-days-old. Seventeen percent were male infants. Clean-catch technique sensitivity was 97% (95% CI 82% to 100%) and specificity was 89% (95% CI 65% to 98%). The contamination rate of clean-catch samples was lower (5%) than the contamination rate of catheter specimens (8%). The sensitivity and specificity of urine cultures obtained using the clean-catch method through the new technique were accurate and the contamination rate was low. These results suggest that this technique is a valuable, alternative method for urinary tract infection diagnosis.Keywords
