Background: Since the introduction of minimally invasive surgery, the number of simulation models available for teaching new surgeons has continued to increase. Objective: To evaluate and validate use of a model for teaching robot-assisted pyeloplasty. Design, setting, and participants: Twenty simulated robot-assisted pyeloplasty procedures were performed by experienced (n = 4) and novice (n = 16) surgeons using a chicken crop model at two different training centers using third- and fourth-generation robotic systems. Outcome measurements and statistical analysis: We evaluated the time needed to perform the procedure, and the sufficiency and patency of the anastomosis. Participants rated the efficiency, face validity, and possible acceptance of the model as part of a structured curriculum on a scale from 0 to10. Statistical significance for comparison of results was set at p

Background: Robot-assisted partial nephrectomy (RAPN) is a challenging procedure that is influenced by a multitude of factors. Objective: To assess the impact of prior surgical experience on perioperative outcomes in RAPN. Design, setting, and participants: In this retrospective multicenter study, results for 2548 RAPNs performed by 25 surgeons at eight robotic referral centers were analyzed. Perioperative data for all consecutive RAPNs from the start of each individual surgeon’s experience were collected, as well as the number of prior open or laparoscopic kidney surgeries, pelvic surgeries (open, laparoscopic, robotic), and other robotic interventions. Intervention: Transperitoneal or retroperitoneal RAPN. Outcome measurements and statistical analysis: The impact of prior surgical experience on operative time, warm ischemia time (WIT), major complications, and margin, ischemia, complication (MIC) score (negative surgical margins, WIT ≤20 min, no major complications) was assessed via univariate and multivariable regression analyses accounting for age, gender, body mass index (BMI), American Society of Anesthesiologists score, PADUA score, and RAPN experience. Results and limitations: BMI, PADUA score, and surgical experience in RAPN had a strong impact on perioperative outcomes. A plateau effect for the learning curve was not observed. Prior laparoscopic kidney surgery significantly reduced the operative time (p
