Objective

To compare, in the same children, urine culture results from bag- versus catheter-obtained specimens with catheter culture as the reference.

Study design

A total of 192 non-toilet-trained children <3 years of age from 2 emergency departments were recruited for this prospective cross-sectional study. All had positive urinalysis results from bag-obtained specimens that were systematically checked with a catheter-obtained specimen before treatment. Results of comparison of urine cultures obtained with these 2 collecting methods are presented.

Results

A total of 7.5% of bag-obtained specimen positive cultures had false-positive results. Twenty-nine percent of bag-obtained specimen cultures with negative results were false negative. Altogether, bag-obtained specimens led to either a misdiagnosis or an impossible diagnosis in 40% of cases versus 5.7% when urethral catheterization was used.
