Purpose: VUR is a common urologic problem in children. Cystoscopic injection of bulking agents (most commonly Deflux) has gained popularity as the first line treatment in the west. However, primarily due to cost factors, it has not gained much popularity in our country. We present our initial experience with cystoscopic Deflux injection for VUR. Materials and Methods: We reviewed our 3-yr experience with the use of Dx/HA (Deflux) for correction of VUR in children and adolescents. All children were evaluated with Ultrasound, MCUG and DMSA renal cortical scan. The indications for surgical correction of VUR included breakthrough infections while on antibiotic prophylaxis, persistent high-grade VUR beyond 3 yrs of age, and presence of significant renal damage on DMSA at diagnosis (in those children presenting with UTI). All children underwent cystoscopic Deflux injection using the standard technique of subureteral injection (0.4-1 ml per ureter). All children received antibiotic prophylaxis for 3-6 months after the injection. USG was done at 1 month and MCUG at 3-6 months after the injection. Results: 33 patients (48 ureters) underwent cystoscopic Deflux injection for correction of VUR. Mean age was 4.5 yrs (1-17 yrs); there were 12 boys and 21 girls. Thirteen children had antenatally diagnosed HDN, while 20 children presented with febrile UTI. All children had primary VUR except one child with persistent VUR 4 yrs after PUV fulguration. The VUR was grade 1-2 in 8, grade 3-4 in 37, and grade 5 in 3 ureters. Every child had at least one ureter with dilating reflux (grades 3,4 or 5). When present, low grade VUR (grade 1or 2) was always on the contralateral side. Only one child received a 2 nd injection after 6 months. Follow-up MCUG was done in 28 children (41 ureters). Complete reflux resolution was achieved in 27 ureters (65%), and the reflux was downgraded in 2 (5%). There were no complications of Deflux injection. Conclusions: Endoscopic correction of VUR in children is a safe and effective minimally invasive treatment for VUR. It stops or downgrades VUR in 70% of ureters. At present, we recommend it as a first-line treatment for grades 1-4 VUR requiring surgical management. Cost is the major factor limiting its use in our country.
