Objectives: To evaluate the feasibility and safety of the EDGE SP1000 single-port robotic platform by performing nephrectomy in live porcine model. Materials and Methods: Robotic nephrectomy was performed on sample group of five gilts using the EDGE SP1000 single-port robotic system. The continuous vital signs of all gilts were monitored throughout the operation to examine the safety of the operation. Data regarding surgical complications and technical difficulties throughout the operation were recorded for future evaluation. Finally, the survival of the sample gilts 2 weeks after the operation were recorded. Results: The robot-assisted nephrectomy yielded an impressive result that all sample gilts survived after 2 weeks. Furthermore, neither surgical complications nor technical difficulties were encountered during the operation. The average duration to establish the operation channel was 12.4 ± 1.52 minutes, the average time taken to install EDGE SP1000 single-port robotic system was 2.8 ± 0.84 minutes, the average time to dissociate and remove the kidney was 47 ± 5.61 minutes, and average total operational duration was 71 ± 5.24 minutes. Most importantly, the surgeon and assistant who were using the system found it convenient and performed excellently during the operation. Conclusions: This study shows that the EDGE SP1000 single-port robotic surgical system is safe and feasible for the use of nephrectomy in gilts. Our further research will expand the application of the EDGE SP1000 system to other urologic procedures and accumulate more preclinical data for further clinical trial.
