An Easy Approach to Obtaining Clean-catch Urine From Infants
Current collection methods leave much to be desired. But a new method may provide a quick alternative.
WHAT’S NEW
Method could reduce need for invasive sampling
A simple suprapubic stimulation technique increased the number of infants who provided a clean-catch voided urine sample within five minutes—a clinically relevant and satisfying outcome. In appropriate patients, use of the Quick-Wee method to obtain a clean-catch voided sample for initial urinalysis, rather than attempting methods with known high contamination rates, may potentially reduce the need for invasive sampling using catheterization or suprapubic aspiration.
CAVEATS
Complete age range & ideal storage temperature are unknown
Neonates and precontinent children older than 12 months were not included in this trial, so these conclusions do not apply to those groups. The intervention period lasted only five minutes, but other published studies suggest that this amount of time is adequate for voiding to occur.6,7 Although this study used soaking fluid stored at 2.8°C, the ideal storage temperature is unknown.
,CHALLENGES TO IMPLEMENTATION
AAP doesn’t endorse clean-catch urine samples
The Quick-Wee method is simple and easy to implement, and requires no specialized training or equipment. AAP guidelines do not endorse the use of clean-catch voided urine for culture, which may be a barrier to changing urine collection practices in some settings.
