Abstract

The Intuitive Surgical DaVinci SP (“Single Port”) robotic platform was approved in 2014, but, recently, there has been a dissemination of the technology with multiple urological procedures successfully adapted to this robot. There are some important differences from prior models. We aimed to share our early outcomes and lessons learned for performing successful single-port robotic-assisted partial nephrectomy (SP-RAPN). This study is a retrospective review of sequential SP-RAPN cases between 7/2019 and 3/2020. We extracted patient characteristics and early surgical outcomes. Surgical tips and tricks were recorded during these cases and compiled. SP-RAPN was successfully completed in 12 patients. Patients mean age was 57.8 ± 11.0 years and median ASA score was 2. Mean tumor size was 3.1 ± 2.2 cm. The average OR Time was 172 ± 41 min and EBL was 68 ± 75 mL. All cases had warm ischemia time < 25 min. Tumor pathology included 8 RCC (6 pT1a, 1 pT1b, 1 pT2a), 2 AML, and 2 oncocytoma. There were no complications. Our top surgical tips involved: (1) patient positioning, (2) port placement, (3) insufflation, (4) air docking, (5) assistant port placement, (6) dynamic arm control, (7) hilar clamping, (8) camera relocation, (9) tumor excision, and (10) extraction and port closure. SP-RAPN is safe and feasible in this series. There are advantages and disadvantages to this platform. As the technology matures and techniques evolve, SP-RAPN may become more appealing. Future studies should focus on long-term outcomes and cost-effectiveness of the SP system.
