Does the use of volumetric bladder ultrasound improve the success rate of suprapubic aspiration of urine?

Abstract

OBJECTIVE: To determine whether a volumetric bladder scanner can improve the success rate of suprapubic aspiration and whether there is an optimal volume of urine required in the bladder before suprapubic aspiration should be attempted. DESIGN: Two-phase prospective study. SETTING: The emergency department of a tertiary children's hospital. SUBJECTS: Children younger than 2 years who required an uncontaminated urine specimen for microscopy and culture. METHODS: In phase one, all patients had an ultrasound followed by suprapubic aspiration. In phase two, patients were randomized to either ultrasound or no ultrasound. RESULTS: In phase one, 37 subjects had ultrasound measurement prior to attem..
