The proposed study builds upon published literature. Herreros et al first described the bladder stimulation technique in newborn infants, which was successful in 86% of newborns with a mean time of 57 seconds. Altuntas et al subsequently demonstrated in a randomized controlled study that the bladder stimulation technique was effective in 78% of newborns, with urine collection occurring within a median time of 60 seconds. Tran et al then demonstrated that this technique is particularly effective for children ≤ 90 days presenting to the emergency department with a contamination rate similar to that of catheterization. Importantly, these findings were replicated by Labrosse et al who also noted that the contamination proportion is not statistically different from the rate seen with catheterization. Thus, while all the previous studies have demonstrated the ease of this approach, without an increase in contamination rates compared with more invasive techniques, previous studies have relied upon trained study personnel, limiting the generalizability of the technique to routine clinical care.
