Abstract | Purpose : The aim of this study was evaluating the efficacy of endoscopic $Deflux^{(R)}$ submucosal injection in children with primary vesicoureteral reflux (VUR). Methods : Retrospective analysis of medical record was conducted on 38 children (59 ureters) who underwent endoscopic $Deflux^{(R)}$ injection due to primary VUR. Data were collected from March 2000 to February 2006. Mean infused amount of $Deflux^{(R)}$ was 0.77 cc. After $Deflux^{(R)}$ injection, patients were reassessed by voiding cystourethrogram (VCUG) 6 months later. Results : The success rate of endoscopic $Deflux^{(R)}$ submucosal injection 6 months later by VCUG was 100% for grade 1 VUR, 87.5% for grade 2, 60% for grade 3, 26.6% for grade 4, 16.6% for grade 5, respectively and there was negatively significant correlation between success rate and grade of VUR (P<.01). Degree of improvement of VUR by endoscopic $Deflux^{(R)}$ submucosal injection was not related to age at diagnosis, time to operation, existence of voiding dysfunction or constipation and infused amount of $Deflux^{(R)}$. However, group with anticholinergics medication had significantly lower success rate than non-medication group (P<0.047). Conclusion : Endoscopic $Deflux^{(R)}$ submucosal injection is effective therapy in patient with primary VUR, especially low grade VUR. It can be not only a useful substitute for prophylaxis with antibiotics, but also an effective management prior to ureteroneocystostomy in children with primary VUR. 목적 : 방광요관역류에 대한 치료법으로 최근 시행되고 있는 내시경적 요관 점막하 $Deflux^{(R)}$ (Dextranomer/hyaluronic acid copolymer) 주사요법의 효과에 대해 알아보고자 하였다. 방법 : 2000년 3월부터 2006년 2월까지 경북대병원 소아과에 내원하여 일차성 방광요관역류로 진단받고 이후 비뇨기과에서 내시경적 $Deflux^{(R)}$ 주사요법을 시행 받은 38명(59요관)을 대상으로 하였다. 의무기록을 통한 후향적 연구를 시행하였으며, 시술 6개월 후에 VCUG를 시행하여 방광요관역류의 치료 성공 및 호전 정도를 조사하였다. 결과 : 대상 환아의 평균연령은 2년 7개월이었으며 남녀비는 17:21이었다. 양측성이 21명(55.3%), 일측성이 17명(44.7%)이었으며 역류를 처음으로 진단받은 뒤 평균 24개월 후에 내시경적 $Deflux^{(R)}$ 주사요법을 시행 받았고 평균 주입량은 0.77 cc 였다. 시행 후 성공률은 Grade 1에서 100%, Grade 2에서 87.5%, Grade 3에서 60%, Grade 4에서 20%, Grade 5에서 16.6%였으며(r=-0.99, P=0.02), 호전률은 단계별로 각각 100%, 75%, 100%, 80%, 83% 이었다(r=-0.39, P=0.21). 즉, 방광요관역류의 단계와 호전률 사이에는 의미 있는 상관관계가 없었으나, 방광요관역류의 단계가 높을수록 성공률이 의미 있게 감소하였다. 그밖에, 방광요관역류의 진단 당시 연령, $Deflux^{(R)}$ 시술까지의 시간, $Deflux^{(R)}$ 주입량, 배뇨장애 유무, 변비의 유무와 성공률은 통계학적으로 의미 있는 상관관계를 보이지 않았고, 항콜린제 사용군에서 성공률이 의미 있게 낮았다. 결론 : 내시경적 요관 점막하 $Deflux^{(R)}$ 주사요법은 역류단계가 낮은 환아에서는 효과적인 치료법으로, 예방적 항생제 요법을 대신하고 개복 수술 전 단계로 시행할 만한 바람직한 방법으로 생각된다. |
