Objectives: To assess long-term postoperative ultrasonographic outcomes of robotic-assisted laparoscopic pyeloplasty (RALP) and of conventional open pyeloplasty (COP) in pediatric patients with ureteropelvic junction obstruction. Methods: Retrospective review of 312 patients who underwent RALP or COP in a single institution. Preoperative and postoperative ultrasounds were used to determine the grade of hydronephrosis. Postoperative assessment included 3 ultrasounds at 0-6, 6-12 and >12 months intervals. Patients were matched by age, etiology of obstruction, grade of preoperative hydronephrosis and gender for case-matched analysis. Results: We identified 212 pyeloplasties that met inclusion criteria, being 58 RALP and 154 COP. Groups were different in age, gender and etiology, but similar in severity of hydronephrosis and follow-up time. At the end of follow-up, complete resolution and success rates were 62% and 74% in RALP and 45% and 70% in COP, respectively. Matching included 105 patients. Complete resolution was higher in RALP (p = 0.004), while median time before improvement was lower (12.3 months RALP vs 29.9 months COP). There was no difference in success rate at the end of follow-up between the groups. Conclusion: RALP shows satisfactory long-term outcomes, comparable to COP. In our cohort, patients who underwent robotic pyeloplasty showed faster resolution of hydronephrosis on ultrasound. © 2012 Journal of Pediatric Urology Company.

What’s known on the subject? and What does the study add? Robot assisted laparoscopic surgery (RALS) is slowly gaining acceptance in the field of paediatric urology. Accumulating data on safety and efficacy when performing paediatric robotic urologic procedures has led paediatric urologists to gradually embrace increasingly more complex reconstructive surgeries. Indeed, the unique and delicate movements generated by the robotic system make this technology ideal for children who often require reconstructive procedures. We critically review the current role of RALS in paediatric urology and to analyse the published data, with a special emphasis on the most common applications. We also propose a structured plan to expedite training and the surgical ‘learning curve’. OBJECTIVES: * To critically review the current role of robot-assisted laparoscopic surgery (RALS) in paediatric urology and to analyse the published data, with a special emphasis on the most common applications. * One of the greatest benefits of RALS has been the ability to truly spread the application of minimally invasive surgery to paediatric surgical patients. The unique attributes of the robotic interface make this technology ideal for children with congenital anomalies, who often require reconstructive procedures. * We also propose a structured plan to expedite training and the surgical ‘learning curve’. PATIENTS AND METHODS: * Currently, almost all urological surgical procedures in children have been performed with the assistance of the robotic interface. * The most commonly performed procedures include pyeloplasty, nephrectomy/hemi-nephrectomy and surgery for vesico-ureteric reflux. * Initial series of bladder augmentation and appendicovesicostomy are available. RESULTS: * Initial results with RALS are encouraging and have shown safety similar to open procedures, and outcomes at least equivalent to standard laparoscopy. * Accumulating data have consistently shown that postoperative analgesia requirements and overall hospital stay are decreased. * However, operative durations are significantly longer than their open counterparts, but this is decreasing as experience accumulates. CONCLUSIONS: * RALS is already part of paediatric urological surgery. * Larger single-institution case series and comparative studies with the open approach and multi-institutional meta-analyses will help to identify the benefits of RALS in paediatric urology.
