Introduction. Urinary tract infections could be the only sign of vesicoureteral reflux (VUR). Vesicoureteral reflux is congenital urinary tract abnormality observed for children. There have not been any studies about methods to diagnose VUR for children by using voiding urosonography (VUS) in Lithuania before.

Material and methods. A total sample of 21 children was investigated from May, 2017 to October, 2017. Nurse catheters the bladder with aseptic rules. SonoVue 0.5-1.0 mL is injected into 200-500 mL sodium chloride 9 mg/mL (0.9%). The prepared system is glued up to a height of 40-60 cm. Ultrasound provides images of the bladder, ureters and kidneys, which is performed during filling and voiding of the child bladder. The duration of procedure is around 30-60 minutes. All examinations were recorded and interpreted by the radiologist.

Results. The study involved 8 (38.1%) boys and 13 (61.9%) girls (p=0.5). The average age of children's is 32.05 (±6.84) months. VUR was diagnosed using VUS method in 13 (61.9%) children: 4 boys (30.77%) and 9 girls (69.23%). VUR grade I-II was 7 (53.85%), VUR grade III-V was 6 (46.15%). No acute complications were observed during the study.

Conclusions. Acute severe allergic reactions were not observed in this study. VUS is suitable for the detection or exclusion of VUR and reduces the number of children being exposed to ionizing radiation.
