Endoscopic treatment of vesico-ureteric reflux in children of early age

The purpose of the study was to study the long-term results of endoscopic treatment of infants and young children with vesicoureteral reflux (VUR). Materials and methods . The analysis of the long-term results of endoscopic correction of reflux in infants and young children operated in the hospital from January 2015 to December 2018. Of these, up to 3 years there were 115 patients (67%), up to a year – 56 children (33%). The duration of follow-up was from 2 to 4 years. Polyacrylamide gel DAM+was used as an implant in 70% of cases (191 ureters). Endoscopic treatment with DAM+ was performed in 77 (70%) children from one to 3 years, as well as 23 patients (41%) of infancy. In other cases, used collagen, uradex. Introduction was carried out by methods of STING, HIT 1 and HIT 2. Results and discussion . Evaluation of the effectiveness of the use of drugs: collagen, DAM+, urodex. The type, degree of reflux, kidney function, presence of concomitant pathology were taken into account in the analysis of the correction results, and the effectiveness was evaluated by changing the degree of reflux and the course of the inflammatory process after 6 months – year after endoscopic correction. The disappearance of reflux after a single application of DAM+ took place in 86% of cases. Re-introduction of the implant was performed in 55 children, 3-fold – 20 at 3–4th degree of reflux. Neoimplantation of the ureter was performed in 9 patients with 4–5th degree of reflux, concomitant pathology of the upper urinary tract and signs of reflux nephropathy. Conclusion. The analysis of long-term results showed that the use of endoscopic techniques of reflux correction with the use of the domestic drug DAM+, including in infants, allows to completely cure reflux or reduce its degree to 1–2, providing optimal conditions for the maturation of the uretero-vesical segment.
