摘要

Robotic partial nephrectomy is a standard procedure in urology, but its widespread use is limited by the high cost and technical constraints of current systems. New robotic systems are being developed to enhance affordability and accessibility, expanding the availability of advanced robotic surgery to a broader range of healthcare facilities and patients. This study evaluates the feasibility and safety of the Toumai system in partial nephrectomy, examining its advanced features and their potential impact on surgical precision and operational efficiency. In this single center study, eleven patients underwent partial nephrectomy using Toumai. Primary endpoints were feasibility and safety, while secondary outcomes included perioperative outcomes. All surgeries were completed successfully without conversion, minimal complications, and no major equipment failures. The median operative time was 107 min, docking time was 8 min, and estimated blood loss was 50 ml. One off-clamp partial nephrectomy was successfully performed and median warm ischemia time was 9 min in the remaining cases. Postoperatively, renal function remained stable, and surgical margins were negative in all cases. These preliminary results suggest that partial nephrectomy can be safely performed using the Toumai robotic system. The system’s advanced features, including sensory feedback, high-frequency response, and enhanced imaging technologies, likely contributed to favorable surgical outcomes with minimal complications. However, these initial findings warrant further validation through larger studies and longer follow-up.
