Objective Suprapubic aspiration ( SPA ) is the gold standard for obtaining uncontaminated urine specimens in young febrile children. The use of real‐time ultrasound ( RTUS ) has been shown to increase the success rate of SPA . The B ladder S can ( BSUS ) Verathon ® is an alternative portable ultrasound device designed to provide automated measurement of bladder volume. Although simple and requiring minimal training, there are no data on the success rate of SPA using the device. Methods An audit of current SPA practice using BSUS in the ED of a tertiary referral children's hospital was conducted. We assessed the success rate of SPA to obtain urine and correlate with BSUS readings and techniques. Results Sixty SPAs (mean age 5.0 months) were observed over an 8‐month period between A ugust 2009 and M arch 2010. The audit showed an overall success rate of 53% (32/60) [95% confidence interval 41–66%]. Success rates were 63%, 32%, 82% and 63% for the largest BSUS readings of 0–9 mL ( n = 8), 10–19 mL ( n = 25), 20–29 mL ( n = 11) and 30+ mL ( n = 16), respectively, or 39% at <20 mL and 70% at ≥20 mL ( P = 0.02). Conclusion The success rate of SPA in ‘real‐life’ non‐standardised clinical practice was low at 53% overall. The BSUS ‐assisted SPA success rate was higher in patients with readings ≥20 mL. These rates are lower than success rates reported using RTUS . Parameters for using BSUS to assist SPA should be established.
