Abstract Background Vesicoureteral reflux (VUR) is present in up to 24% of children with neurogenic bladder secondary to meningomyelocele. Endoscopic management of VUR has been an emerging approach, especially since the continuous development of this technique has translated in comparatively high success rates. In this study, we assess the efficacy of subureteric injections of dextranomer/hyaluronic acid copolymer in managing VUR secondary to meningomyelocele in pediatric patients.Materials and methods All patients aged less than 12 years who underwent endoscopic management for secondary VUR of grades III–V due to meningomyelocele were observed. The diagnosis and classification of VUR was done via a MCUG. All patients underwent clinical assessment, renal function tests, urine microscopy with culture, KUB ultrasound, and dimercaptosuccinic acid (DMSA) scan before and after the intervention.Results A total of 19 children (38 renal units) were evaluated and followed up. The mean age at presentation and intervention was 44 ± 34.6 months and 45.7 ± 35.2 months. The most common grade of reflux at presentation was grade IV (42.1%) followed by V (26.3%). A complete symptomatic relief and treatment success was achieved in 29 renal units (76.3%) following a single injection. A second injection was sufficient to achieve symptomatic relief in the remaining nine renal units (23.6%). None of the patients required a third injection or open surgery.Conclusion The endoscopic treatment of secondary VUR grades III, IV, and V due to meningomyelocele with dextranomer/hyaluronic copolymer paste in children younger than 12 years is safe and effective alternative minimally invasive surgery with low morbidity.
