Objective: Demographical, pre-transplantation and post-transplantation features and post-treatment results of four pediatric cases, who had vesicoureteral reflux (VUR) in the graft kidney, were discussed. Methods: Transplantation age, primary diagnosis, VUR to pretransplantation in native kidneys, history of bladder dysfunction, bladder capacity, results of urodynamic studies, donor and its features, induction treatments and ongoing immunosuppressive treatments, acute rejection episodes, CMV and BK infections, VUR grade in the renal graft, DMSA results, treatment type and its outcomes, and the renal graft functions of four patients who underwent kidney transplantation at Tepecik Training and Research Hospital between 2008 and 2016 and for whom VUR was determined via voiding cystourethrography (VCUG) due to recurrent urinary tract infections, were evaluated. Results: All of four cases were female. Their mean transplantation age was 8.7 years (5-16). High grade (Grade 4) VUR was determined in the graft kidney in all but one. DMSA included multiple scar foci apart from one case having low grade VUR. Cases were primarily treated endoscopically and then by open surgery. Spontaneous recovery occurred in one case. Graft dysfunction was not observed in any of the cases. Conclusion: VUR is an important risk factor in recurrent urinary tract infections after post-transplantation. A special assessment should be done for the patient in the presence of VUR and conservative and surgical treatments should be executed together. It should be remembered that VUR can be spontaneously regressed by the bladder capacity increasing treatments and prophylaxis.
