V9-09: Novel Robotic System for Single Port Partial Nephrectomy: Initial Experience and Technique
VideoIntroductions and Objectives
Single-port (SP) laparoscopic surgery has been developed with the goal of accelerating patient recovery and improving cosmesis. In this video we describe a new purpose-built robotic system for performing SP robotic partial nephrectomy.
This is a prospective IRB-approved study performed SP robotic renal surgery on 11 patients, including 4 patients who underwent SP robotic partial nephrectomy using a new SP robotic system. Video footage was obtained to describe the feasibility and safety of using this new robotic system. Perioperative data including patient characteristics and post-operative complications were prospectively collected. The patients were followed for 3 years post-operatively for oncologic and functional outcomes.
A total of 4 patients were enrolled in this study to undergo SP robotic partial nephrectomy. Median age was 62.5 years, median BMI was 27.2, and mean eGFR was 68.6 mL/min. No cases were converted to open procedures. There were no major complications. Two patients had Clavien 2 complications of post-operative anemia requiring transfusion. At 30 day follow up mean eGFR was 74.1 mL/min. At 3-year follow up, all patients were disease free and demonstrated preserved renal function.
We describe the steps and present the outcomes from the first application of a new SP robotic system constructed specifically for single-port surgery. SP robotic partial nephrectomy was performed in 4 patients without need for conversion to traditional laparoscopic or open surgery. There were no major complications. Functional and oncologic outcomes were comparable to traditional robotic technique.
