ObjectiveThe objective of this study was to compare contamination rates in urine samples obtained by transurethral catheterization and clean-catch methods in preschool children aged 2 to 5 years.MethodsA retrospective, chart review was performed on patients evaluated in our emergency department over a 6-month period who had a urine culture obtained by either transurethral catheterization or clean-catch methods. The charts were reviewed for urine bacterial colony counts and divided into positive, negative, or contaminated cohorts. Demographic data were collected as well.ResultsFour hundred sixty patients met inclusion for this study. Of these patients, there were 120 samples collected by catheter (26.1%) and 340 samples collected by clean-catch method (73.9%).Female patients comprised 73% of the eligible samples (n = 336), and 27% were male (n = 124). Contamination rates significantly varied by collection method (P < 0.0001), with only 9 contaminated catheter samples (7.5%) and 125 contaminated clean-catch samples (36.76%). Contaminated samples were found in 122 of 336 female urine samples (36.3%), and 12 of 124 male urine samples (9.7%). There were no associations found between contamination rates and age within either sex.ConclusionsOur study demonstrated a higher urine culture contamination rate in preschool age children in the clean-catch method group compared with the transurethral catheterization group. This finding was particularly strong within the female subset, which could partially be accounted for by the small male sample size.Copyright © 2021 Wolters Kluwer Health, Inc. All rights reserved.
