To evaluate the safety and feasibility of using the EDGE SP1000 single-port surgical robot for laparoscopic partial ureterectomy with end-to-end anastomosis in a live pig model.

The EDGE SP1000 single-port robotic surgical system was used to perform laparoscopic partial ureterectomy with end-to-end anastomosis in pigs. Vital signs of the pigs were monitored during the surgery, and surgical difficulties and complications were recorded. The survival of the pigs was observed for two weeks post-operatively.

All pigs survived for two weeks after the surgery, with no surgical complications or technical difficulties encountered during the procedure. The average time for establishing the surgical access in five pigs was (15.0±1.2) min, while the installation time for the EDGE SP1000 single-port surgical robot system was also (5.6±0.6) min. The time for ureterectomy was (8.8±1.3) min, the time for end-to-end anastomosis of the ureter was (39.2±2.3) min, and the total surgical time was (89±5) min, and intraoperative blood loss was (1.20±0.24) mL. The surgical team highly praised the performance of the surgical system.

This study confirms that the EDGE SP1000 single-port robotic surgical system is safe and feasible for laparoscopic partial ureterectomy with end-to-end anastomosis in pigs. The next step is to evaluate the safety and effectiveness of the EDGE SP1000 system in other surgical procedures, providing more reliable preclinical data support.
