Abstract
IntroductionThe acquisition of non-contaminated urine samples in pre-continent infants remains a challenge. The Quick Wee method uses bladder stimulation to induce voiding. A previous randomized trial showed a higher rate of voiding within 5 minutes using this method. We evaluated this method in an Irish hospital providing secondary care.MethodsA non-blinded, randomized, controlled trial was carried out. Eligible infants were between 1 and 12 months of age, who required urine sampling as part of clinical care. Participants were randomly allocated to receive the intervention (Quick Wee Method—supra-pubic stimulation with cold saline) or the control (usual care—clean catch with no bladder stimulation) for 5 min. Primary outcome was voiding of urine within 5 min.ResultsA total of 140 infants were included in this study (73 in intervention group; 67 in control group). Baseline characteristics were similar. 25% in the intervention group passed urine in the 5-min trial period compared with 18% in the control group [P = 0.4, absolute difference 7% (95% confidence interval: − 7% to + 20%)].ConclusionThe Quick Wee method is a simple and inexpensive intervention that did not show a statistically significant increase in urine samples obtained in pre-continent infants.

The acquisition of non-contaminated urine samples in pre-continent infants remains a challenge
A study by Selekman based on the experience of 2726 parents of infants who underwent urinary catheterization reported that 56% of parents were extremely distressed by the procedure [2]
The Quick Wee method was an effective method for obtaining clean catch urine specimens in infants 1–12 months of age with the primary outcome being achieved in 31% of the intervention group versus 12% of the control group [P < 0.0001, absolute difference 19%, number needed to treat = 5 (NNT)] [5]
Summary
The acquisition of non-contaminated urine samples in pre-continent infants remains a challenge. In a study by Tosif of children aged 2–48 months, 139 (64%) had a Recently, the Quick Wee method of bladder stimulation, which uses a non-invasive strategy to induce voiding within 5 minutes, was evaluated by Kaufman in a tertiary care centre. In this evaluation, the Quick Wee method was an effective method for obtaining clean catch urine specimens in infants 1–12 months of age with the primary outcome being achieved in 31% of the intervention group versus 12% of the control group [P < 0.0001, absolute difference 19%, number needed to treat = 5 (NNT)] [5]
