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<0.01). 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.
