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.
机器人辅助部分肾切除术是泌尿外科的一项标准手术，但目前系统的高成本和技术限制阻碍了其广泛应用。新型机器人系统正在研发中，以提高可承受性和可及性，将先进的机器人手术推广到更多的医疗机构和患者。本研究评估了图迈系统在部分肾切除术中的可行性和安全性，研究了其先进特性及其对手术精度和操作效率的潜在影响。在这项单中心研究中，11例患者使用图迈系统接受了部分肾切除术。主要终点是可行性和安全性，次要结果包括围手术期结果。所有手术均成功完成，无需中转，并发症极少，且无重大设备故障。中位手术时间为107分钟，对接时间为8分钟，估计失血量为50毫升。成功实施了1例无阻断部分肾切除术，其余病例中位热缺血时间为9分钟。术后，肾功能保持稳定，所有病例手术切缘均为阴性。这些初步结果表明，使用图迈机器人系统可以安全地进行部分肾切除术。该系统的先进特性，包括感觉反馈、高频响应和增强成像技术，可能有助于实现良好的手术效果，并发症极少。然而，这些初步发现需要通过更大规模的研究和更长时间的随访进行进一步验证。
