Evidence supporting the safe use of the single-port (SP) robot for partial nephrectomy is scarce. The purpose of this study was to compare perioperative outcomes for patients undergoing robotic assisted SP vs multi-port (MP) partial nephrectomy (PN) in a time-matched cohort. All patients with clinically localized renal masses who underwent robotic PN from January 2019 to March 2020 were evaluated. Patients were stratified according to SP vs MP approach. Postoperative analgesia was administered in accordance with department-wide opioid stewardship protocol and outpatient opioid use was tracked. Total of 78 patients underwent robotic PN with 26 patients in the SP cohort. The majority of renal masses had low-complexity (53, 67.9%) R.E.N.A.L. nephrometry scores, without a significant difference between the two cohorts (p = 0.19). A retroperitoneal approach was performed in 16 (20.5%) patients overall, though more commonly via the SP robotic approach (13 vs 3, p
