Since traditional open surgery yields a nearly 95% clinical success rate, it is difficult to determine which approach is most advantageous to patients. Despite excellent clinical outcomes with the open approach, many pediatric urologists are shifting towards newer RAL approaches, claiming faster recoveryand improved cosmesiswith a nominal increase in surgical cost in the absence of randomized controlled trials (RCTs). We designed a pilot comparative effectiveness trial of open versus robotic pyeloplasty in pediatric patients. METHODS: Non-obese (<95th% BMI for age) patients age 2 – 8 years old diagnosed with a UPJO were approached by a research assistant regarding enrollment into the RCT. Upon signing consent, patients were randomized to OP or RALP and scheduled for surgery. The surgical team was blinded as to the randomization assignment until the morning of the scheduled operation. Intraoperatively, patients underwent cystoscopy, retrograde pyelogram and retrograde stent placement with extraction string, then underwent either open or robotic pyeloplasty with a similar transversalis plane block by anesthesia and the same dressings were applied. Patients, families and nursing staff were blinded as to the approach used for the first 24 hours postoperatively. We then assessed our primary outcomes of pain scores with each nursing assessment, total length of stay. RESULTS: (91%): 5 underwent open pyeloplasty and 5 robotic pyeloplasty. All patients were symptomatic with flank pain and associated nausea/vomiting. Mean age was 5.4 years, 7 were male, and had an average BMI of 16.7kg/m2. UPJO was right-sided in 4 patients (with one solitary kidney). On exit interview at 24 hours post surgery, blinding was deemed adequate by families and nursing staff, with only 40% correctly identifying the procedure. There were no intraoperative complication and one 30 day Clavien 3b complication (a stent removal in the operating room). At last follow-up, all patients remained asymptomatic with stable or improved hydronephrosis. CONCLUSIONS: We successfully randomized and blinded 10 children to undergo either open or robotic surgery. Using current recruitment strategy and expanding inclusion criteria, we are planning a multi-institutional comparative effectiveness trial comparing open to robotic pyeloplasty in the pediatric population.
