Purpose: The aim of this study is to investigate the renal ultrasonographic findings in children with vesicoureteral reflux (VUR).
Methods: We retrospectively reviewed the medical records of 83 patients who were diagnosed with VUR and underwent ultrasonography at Ilsan hospital between January 2000 and December 2010.
Results: Among 166 renal units, 108 (65.0%) were found to have vesicoureteral reflux (VUR). Fifty-one (73.9%) had VUR in renal units with abnormal ultrasonography (USG), whereas 57 (58.7%) had VUR in renal units with normal USG. Abnormal USG findings were independent risk factors for VUR (Odds ratio, 1.98; 95% CI, 1.01-3.89; =0.045). In renal units with VUR, the number of normal USG finding was 52.8%, and the abnormal findings were as follows; increased cortical echogenicity 16.7%, hydronephrosis 17.6%, megaureter or ureter dilatation 8.3%, hydronephrosis and ureter dilatation 1.9%, duplication of ureter 1.9%, and atrophic kidney 0.9%. The prevalence of VUR was relatively higher in renal units with hydronephrosis (23/19, 82.6%), ureter dilatation (9/9, 100%), duplication of ureter (2/3, 66.6%), and atrophic kidney (1/1, 100%).
Conclusion: Our study indicates that VUR was associated with abnormal USG findings. When there are abnormal USG findings such as hydronephrosis, ureter dilatation, duplication of ureter, and atrophic kidney in children with UTI, VCUG is recommended to detect VUR after controlling UTI.
