Purpose : Voiding cystourethrography(VCUG) is required to detect vesicoureteral reflux(VUR), which may manifest as urinary tract infection(UTI) in children. It is well known that VCUG can cause UTI(post-VCUG UTI). In this study, risk factors for post-VCUG UTI and the preventive effect of antibiotics against this complication of VCUG were explored.
Methods : Medical records of 284 patients who underwent VCUG at our hospital in 2007 were reviewed retrospectively. The incidence of post-VCUG UTI and risk factors for post-VCUG UTI, and the impact of antibiotic use on prevention of post-VCUG UTI were evaluated. According to antibiotics usage, we divided the enrolled patients into 4 groups of noantibiotics group, prophylactic antibiotics group(prophylactic antibiotics having been used before), antibiotics-for-VCUG group(antibiotics added for VCUG) and antibiotics-for-treatment group(treatment dose of antibiotics).
Results : Seven of 284 children(2.5%) developed UTI after they underwent VCUG. Highgrade(gradeIII) VUR was the only statistically significant risk factor(odds ratio[OR] 6.266, P=0.026) for post-VCUG UTI, while sex, age, and other anomalies of urinary system were not significant. Five post-VCUG UTI cases belonged to prophylactic antibiotics group. Antibiotics use (three groups using antibiotics vs. no-antibiotics group) or addition of antibiotics for VCUG (antibiotics-for-VCUG vs. other groups) did not have any effect on prevention of post-VCUG UTI.
Conclusion : The risk factor for post-VCUG UTI was high-grade VUR. Antibiotics use did not prevent post-VCUG UTI in this study.
