[The late results of the surgical treatment of vesicorenal reflux in children].

1-27-year follow-up results are available for 455 patients who at the age of 3 months-14 years were operated on vesicoureteral segments with reflux of the II, III and IV degree. Overall 648 interventions were made, of them 78 according to Grégoir-Lich (54 patients). Good results were obtained in 91.02% of cases (reflux degree II and III). Resection of distal ureter with its implantation into the bladder by Politano-Leadbetter technique was performed in 401 patients on 570 vesicoureteral segments. In reflux degree II and III good outcomes were reached in 97.37%, degree IV in 90.80% of the cases. Histological findings on the resected ureters showed that pathogenetically the reflux was initiated by structural changes in distal ureteral wall which occurred as a congenital or acquired condition. The removal of the destroyed segment contributed to advanced treatment effects. The reflux elimination favoured renal growth and clinical improvement of pyelonephritis. X-ray images of 150 kidneys (95 patients) 10-26 years after the reflux discontinuation reflected a 1.5-5-fold increase in the kidney size. Before stabilization parenchymal sclerosis developed the following 1-2 to 10-15 years.
