Endoscopic correction of vesicoureteral reflux in children

Introduction: Dextranomer/hyaluronic (Dx/HA) acid is the only tissue-augmenting agent approved by the Food and Drug Administration (FDA) for the vesicoureteral reflux (VUR) treatment. Objectives: We aimed to evaluate short-term outcomes of the Dx/HA in patients who had undergone subureteric injection. Patients and Methods: In this study, 30 patients with VUR diagnosis who had indications for open surgery were enrolled in the study. Patients underwent subureteric Dx/HA injection. Additionally patients underwent a one-year follow up period, subsequently. Follow up included urine analysis, urine cultures and kidney and urinary tract ultrasonography study. Results: Of a total 30 patients, 8 patients (27%) were male and 22 patients (73%) were female. The mean age of patients was 25.19 ± 0.70 months. Postoperative VUR resolution was observed in 28 patients (93.3%). Moreover, during one year follow up, urinary tract infection (UTI) was not reported in patients. However, recurrent VUR was detected in 8 patients (27%) during ultrasonography follow up. Analysis showed no significant difference of recurrence in VUR between males and females (P = 0.285) and VUR severity (P = 0.1). There was a significant relationship between recurrent UTI history before intervention and VUR recurrence after subureteric injection (P = 0.007). Conclusion: Dx/HA acid subureteric injection provides acceptable resolution rate among VUR patients, but its biodegradability causes VUR recurrence during one-year follow up.
