Résumé : Purpose: This multicentric international retrospective study aimed to report the outcome of robot-assisted extravesical ureteral reimplantation (REVUR) in patients with unilateral vesico-ureteral reflux (VUR). Methods: The medical records of 55 patients (35 girls, 20 boys) underwent REVUR in four international centers of pediatric robotic surgery for primary unilateral VUR were retrospectively reviewed. Patients’ average age was 4.9 years. The preoperative grade of reflux was III in 12.7%, IV in 47.3% and V in 40%. Twenty-six patients (47.3%) presented a loss of renal function preoperatively and 10 (18.1%) had a duplex system. Results: Average robot docking time was 16.2 min (range 5–30). Average total operative time was 92.2 min (range 50–170). No conversions or intra-operative complications were recorded. All patients had a bladder Foley catheter for 24 h post-operatively. Average hospital stay was 2 days (range 1–3). Average follow-up length was 28 months (range 9–60). We recorded three (5.4%) postoperative complications: 1 small urinoma resolved spontaneously (II Clavien) and 2 persistent reflux, only one requiring redo-surgery using endoscopic injection (IIIb Clavien). Conclusion: REVUR is a safe and effective technique for treatment of primary unilateral VUR. The procedure is easy and fast to perform thanks to the 6° of freedom of robotic arms. The learning curve is short and it is useful to begin the robotics experience with a surgeon expert in robotic surgery as proctor on the 2nd robot console. The high cost and the diameter of instruments remain the main challenges of robotics applications in pediatric urology.
