Abstract

Vesicoureteral reflux (VUR) is one of the most common anomalies of the urinary
system in children. Contrast-enhanced voiding urosonography (ceVUS) is one of the best methods in
VUR diagnosis. This study compared characteristics associated with VUR specific images and categorized
patients according to a particular VUR grade. The study included 183 children. VUR was detected
in 38.9% of patients, mean age 1.7±1.1 years. Grade II VUR was most common (60.3%), followed
by grade III (29.4%). Study results showed that VUR occurred irrespective of age, gender, previous
ultrasound findings, causative agent, and severity of urinary tract infection (UTI ). VUR was more
common in children with recurrent UTI . In the group of children with the first UTI not caused by
Escherichia coli or with recurrent UTI , boys more commonly suffered from severe VUR (grade IV-V;
66.7%), while girls suffered from moderate VUR (grade II -III ; 100%). In this study, the incidence of
VUR in prenatally diagnosed hydronephrosis was 28.6%. It is necessary to develop an algorithm for
the treatment of children after UTI in Croatia, which should include ceVUS. All children with possible
VUR should be referred to a specialized center where it is possible to perform ceVUS.
