BACKGROUND: The selection of best surgical approach for treatment of vesico-ureteral reflux (VUR) in the pediatric population remains debated. This study aimed to report the results of a multicenter survey about the current trends in surgical management of pediatric VUR.
METHODS: An online questionnaire-based survey was performed, with participation of 6 international institutions. All children (age <18 years) affected by primary III-V grade VUR, who were operated over the last 5 years, were included. The incidence of each VUR intervention, patients’ demographics and outcomes were analyzed.
RESULTS: A total of 552 patients (331 girls), with a median age of 4.6 years (range 0.5-17.6), were included. Deflux® injection (STING) was the most common technique (70.1%). The multicenter success rate after single treatment was significantly lower after STING (74.4%) compared with the other treatments [p=0.001]. Persistent VUR rate was significantly higher after STING (10.8%) compared with the other treatments [p=0.03]. Choosing endoscopy over surgery mean reducing Clavien Dindo grade 2 complications by 5% but increasing redo procedure rate by 7%. STING was the most cost-effective option.
CONCLUSIONS: This survey confirmed that the choice of the technique remains based on surgeon’s preference. Deflux® injection currently represents the first line therapy for primary VUR in children and the role of surgical ureteral reimplantation is significantly reduced. STING reported acceptable success rate, less post-operative complications and lower costs but higher failure and re-operation rates and related costs compared with the other surgical approaches. The adoption of laparoscopy and robotics over open reimplantation remains still limited.
