BACKGROUND: Vesicoureteric reflux (VUR) is an important association of paediatric urinary tract infection (UTI) found in 30-50% of all children presenting with first UTI. Contrast-enhanced voiding ultrasonography (ceVUS) has become an important radiation-free method for VUR detection in children. Its sensitivity in detecting VUR has greatly improved due to the development of the contrast-specific ultrasound techniques and the introduction of the second-generation ultrasound contrast agent, superseding the diagnostic accuracy of standard radiological procedures.AIM: This article aimed to summarise the current literature and discuss the first local pilot study performed in our institution on detection of vesicoureteric reflux by contrast-enhanced voiding ultrasonography with second- generation agent (SonoVue, Bracco, Italy).MATERIAL AND METHODS: Retrospective review of the first 31 ceVUS (24 girls, 7 boys) was presented.  Age range was 2 months to 18 years (mean = 6.4 ± 4.9).RESULTS:  All examinations were well tolerated without any adverse incident. VUR was shown in 20 (64.5%) children in 32/62 (51.6) nephroureteral units (NUUs). In 18 NUUs, VUR was grade II/V, in 11 Grade III/V and in 3 grade IV/V, respectively. Urethra was shown in 19/31 children and in all boys, without pathological finding. In two girls spinning top urethra has been detected. Subsequent urodynamic studies revealed functional bladder problem in both. CONCLUSIONS: Contrast-enhanced voiding urosonography using intravesical second generation ultrasound contrast agent could be recommend  as a valid alternative diagnostic modality for detecting vesicoureteral reflux and evaluation of the distal urinary tract in children, based on its radiation-free, highly efficacious, reliable, and safe characteristics.
