Purpose : We checked voiding cystourethrography (VCUG) in patients with congenital hydronephrosis (CHN) and followed up the occurrence of urinary tract infection(UTI) in these patients. And we tried to figure out the relationship between CHN and VUR and UTI.
Methods : We performed a retrospective study in 122 CHN patients who received VCUG from 2002 to 2008 at Ajou University Hospital. We executed logistic regression, chi-square test and T-test using version 16.0 SPSS package for the statistical analysis. P<0.05 was regarded as significant.
Results : Most patients with CHN were male (73%) and there was a tendency of preferences for unilateral (77%) and left (84%) occurrence of hydronephrosis. The incidence of VUR was 18.9% among 122 CHN patients and no laterality difference was found to the severity of VUR or hydronephrosis. The incidences of VUR and UTI was higher in group of higher grade (III-IV) CHN patients, when compared to the lower group, respectively. When VUR was present in CHN patients, the incidence of UTI during infancy was also higher.
Conclusion : The incidence of VUR was higher in patients with higher grades of CHN. The incidence of UTI during infancy was higher when VUR was present in the CHN patients.
Key words: Congenital hydronephrosis | Vesicoureteral reflux (VUR) | Renal ultrasound | Voiding cystourethrography (VCUG)
