Purpose: We evaluated the long-term results of endoscopic Deflux$^{(R)}$ injection for treating vesicoureteral reflux (VUR) in children. Methods: Between September 2004 and September 2014, 243 children (137 boys and 106 girls) with a mean age of 53 months underwent Deflux$^{(R)}$ injection. Our clinical protocol included radionuclide voiding cystography (RNC) at postoperative 3 months, 1 year and 3 years to assess the VUR resolution. Results: The cure rates at 3 months, 1 year, and 3 years by patients were 70.8%, 64.3%, and 65.6% for the total patients and 79.2%, 75.2%, and 76.4%, for the ureters, respectively. The recurrence rate of postoperative febrile urinary tract infection (UTI) was 20% in patients without VUR at postoperative 1 year. Twenty patients undergoing ureteroneocystostomy (UNC) significantly had younger age (P=0.003), higher VUR grade (P<0.001), and lower success rates of Deflux$^{(R)}$ injection (P<0.05). On univariate analysis, older age (P=0.014) and lower grade of VUR (P=0.031) were the significant predictors of a successful outcome. But there was none on multivariate analysis. Younger age, especially age of 0-12 month-old, was the only significant predictor of postoperative febrile UTI recurrence on both univariate and multivariate analysis. Conclusion: Deflux$^{(R)}$ injection is efficacious with a low complication rate for the anti-reflux procedure in children. There is low recurrence rate of UTI though VUR persists, and high probability of no VUR at 3 years if no VUR at 1 year. It is recommendable not to perform follow-up RNC at 3 years routinely if no VUR at 1 year.

배뇨방광요도조영술은 소아의 비뇨기과적 투시 검사에서 가장 중요한 검사이다. 배뇨방광요도조영술로 비뇨기계의 해부학적 구조와, 방광 요관 역류의 유무를 검사할 수 있다. 환자치료의 궁극적인 목표를 달성하려면 배뇨방광요도조영술을 적절하게 이해하고 수행하는 것이 중요하다. 이에, 심층적인 배뇨방광요도조영술의 술기 순서 및 기법에 대해 소개하였다. 또한, 배뇨방광요도조영술과 관련된 요령과 함정들을 다루었다.
