Abstract
INTRODUCTION: Single-port (SP) robotic surgical system performs well in small anatomical spaces, which makes it suitable for retroperitoneal robotic partial nephrectomy (RPN). However, there is limited evidence comparing the safety and feasibility of SP RPN to multiport (MP) RPN. To address this gap in evidence, we sought to analyze and compare the safety of retroperitoneal RPN between SP and MP approaches.
METHODS: This is a retrospective cohort study using data from the Single Port Advanced Research Consortium (SPARC) and a multicenter database of patients who underwent retroperitoneal RPN using either SP or MP between 2017 and 2023. Baseline, perioperative, and postoperative data were compared using t-tests, Mann-Whitney U test, χ
RESULTS: A total of 286 patients (SP RPN, n = 86 [30%]; MP RPN, n = 200 [70%]) underwent retroperitoneal RPN. R.E.N.A.L nephrometry score and tumor location were significantly different between the 2 groups. Notably, the ischemia time was significantly shorter in the MP group (16 vs. SP, 22 minutes, P < 0.001). Adjusting for baseline characteristics, the ischemia time was approximately 7.89 minutes longer for patients in the SP group compared to the MP group, on average (95% CI: 5.87, 9.92; P < 0.001). No significant differences were observed in operative time, EBL, blood transfusion, conversion rates, LOS, PSM, and overall 30-day postoperative complications between the 2 groups.
CONCLUSION: Our study shows that retroperitoneal SP and MP RPN have comparable perioperative and postoperative outcomes, except for the longer ischemia time in the SP platform. SP RPN is a safe and viable alternative; however, further research is needed to explore its potential benefits, cost-effectiveness, and long-term oncologic outcomes.
