What is Robot-assisted Partial Nephrectomy with the Newly Developed KangDuo Surgical Robot Versus the da Vinci Si Surgical System: A Double-center Prospective Randomized Controlled Noninferiority Trial about?

## Background: The kangduo surgical robot (kd-sr) was recently developed in china. ## Objective: To compare the safety and efficacy of the kd-sr versus the da vinci si surgical system (dv-ss-si) for robot-assisted partial nephrectomy (rapn). ## Design, setting, and participants: A double-center prospective randomized controlled noninferiority trial of patients aged 18-75 yr with a suspicion of t1a n0m0 renal cancer (renal nephrometry score ≤9) was conducted. ## Intervention: Rapn with the kd-sr versus the dv-ss-si. ## Outcome measurements and statistical analysis: The primary endpoint was the success rate of operation. the operation was successful if (1) there was no open or laparoscopic conversion, (2) the warm ischemia time was <30 min for renal nephrometry scores of 4-6 or 40 min for renal nephrometry scores of 7-9, and (3) the pathological margin was negative. the secondary endpoint was the estimated glomerular filtration rate (egfr). a threshold of 10% was set to demonstrate noninferiority. ## Results and limitations: From september 2020 to march 2021, 100 participants were enrolled, of whom 99 (49 in the kd-sr group and 50 in the dv-ss-si group) were finally included in the f
