Abstract

<abstract abstract-type="main" id="apa13019-abs-0001"> <title>Abstract</title> <sec id="apa13019-sec-0001" sec-type="section"> <title>Aim</title> <p>Guidelines recommend collecting urine with suprapubic aspiration or urethral catheterisation in infants with a suspected urinary tract infection (UTI), but the invasiveness of these methods continues to drive research on new urine collection devices. We studied children with a suspected UTI, who had not been toilet trained, to compare a new midstream urine collector and catheterisation.</p> </sec> <sec id="apa13019-sec-0002" sec-type="section"> <title>Method</title> <p>During this prospective controlled diagnosis study of 94 children, urine collection was performed using the midstream collector and then controlled via catheterisation when the urine dipstick was positive.</p> </sec> <sec id="apa13019-sec-0003" sec-type="section"> <title>Results</title> <p>When end stream samples collected by the midstream collector were compared to catheter samples, the results were inconsistent in 23.4% of cases, similar to the inconsistent results between first stream samples discarded by the device and the catheter samples (21.3%). Interestingly, the overall rate of sample contamination in the bag of the midstream collector was lower than that reported in previously published studies and there were no false positive bag results.</p> </sec> <sec id="apa13019-sec-0004" sec-type="section"> <title>Conclusion</title> <p>The midstream collector did not appear to provide additional benefits to classic collection bags. A sterile collection method, such as suprapubic aspiration, catheterisation or clean catch, is still mandatory for diagnosing urinary tract infections in children who are not toilet trained.</p> </sec> </abstract>
