Introduction Vesicoureteral reflux (VUR) is an anatomic or functional disorder, and it is a condition associated with renal scarring, hypertension, and end-stage renal disease. Renal damage can be prevented by appropriate medical and surgical intervention for selected patients. Objectives The objective of this study was to retrospectively analyze the surgically treated patient group of this study in reference to the risk analysis criteria used in European Association of Urology (EAU), European Society for Paediatric Urology (ESPU) guidelines to see the outcome of the study management protocol within the last 15 years in respect to this risk analysis. Study design A total of 686 patients who were operated upon in a single institution for VUR between 1997 and 2016 were retrospectively analyzed. According to the criteria in EAU/ESPU guidelines, the patients were classified into three groups: low, medium, and high risk. Risk factors were compared between the groups. Results The patient numbers for low, medium, and high risk were 92 (13.4%), 485 (70.7%), and 109 (15.9%), respectively. In the high-risk group, surgeons tended to do more ureteroneocystostomy (UNC) (82.6%), whereas in the low-risk group, surgeons tended to do more subureteric injection (STING) (76.1%). The success rates for STING and UNC were found to be 75% and 93%, respectively. Although there was a difference in success rates among patients treated with STING or UNC, this difference was not statistically significant in success rates regarding risk groups for patients treated with STING or UNC. Discussion The most recent guideline was that which was published by the EAU/ESPU organization in 2012. This guideline is established based on the risk analysis. The analysis revealed that patients in the low-risk group tended to undergo endoscopic surgery treatment method, whereas patients in the high-risk group tended to undergo open surgery. Therefore, the study management over the last 10 years has been mainly in line with the current recommendations. Conclusion The analysis shows that when the patients are classified according to the EAU/ESPU risk classification, surgeons tended to perform more endoscopic and more open surgery for the low- and high-risk groups, respectively. Although each surgical modality had similar success rates in each group, open surgical results were overall much higher than those of endoscopic surgery in each group. This was a specifically important finding in high-risk group where the endoscopically treated group of patients was small in number, and the need for a definitive correction is essential in this group because of increased risk of renal injury.
