Abstract

Introduction: Robot-assisted surgery is increasingly utilized in urology, providing enhanced precision and potentially improving patient outcomes. The Saroa surgical system is a novel robotic platform featuring integrated haptic feedback and compatibility with standard laparoscopic instruments. This study reports the first clinical application of Saroa in robot-assisted radical nephrectomy (RARN) and nephroureterectomy (RANU).

Methods: A single-center, retrospective analysis was conducted on 11 patients who underwent RARN or RANU using Saroa between January 2024 and March 2025. Perioperative outcomes, complications, grasping force data, and Likert scale evaluations from surgeons and assistants were analyzed.

Results: All procedures were completed without conversion or major complications. No transfusions or Clavien-Dindo grade ≥ 3 complications occurred. Haptic feedback was associated with reduced grasping force (mean force: 2.94 N with feedback off vs. 0.49 N at 2.0× setting). Surgeons rated Saroa higher for haptic naturalness and grasp control, while overall satisfaction was greater with the da Vinci system. Assistants reported significantly greater technical engagement with Saroa (p = 0.042), reflecting enhanced educational value.

Conclusions: RARN and RANU using the Saroa system appear safe and feasible, even in early clinical use. The system's compact design, tactile feedback, and cost-effectiveness suggest potential for broader adoption and training utility. Further prospective studies are warranted to confirm its clinical and educational benefits.

应用新型Saroa手术系统进行机器人辅助肾切除术和肾输尿管切除术的初步经验。

导读：机器人辅助手术越来越多地应用于泌尿外科，提供更高的精度和潜在的改善患者的结果。Saroa手术系统是一种新颖的机器人平台，具有集成的触觉反馈和与标准腹腔镜仪器的兼容性。本研究报道了Saroa在机器人辅助根治性肾切除术（RARN）和肾输尿管切除术（RANU）中的首次临床应用。方法：对2024年1月至2025年3月期间使用Saroa进行RARN或RANU的11例患者进行单中心回顾性分析。分析围手术期结局、并发症、抓握力数据和外科医生和助手的李克特量表评估。结果：所有手术均顺利完成，无明显并发症。无输血或Clavien-Dindo级≥3级并发症发生。触觉反馈与抓握力降低有关（反馈关闭时的平均力为2.94 N， 2.0倍设置时为0.49 N）。外科医生对Saroa的触觉自然度和抓握控制的评价更高，而对达芬奇系统的总体满意度更高。助理报告说，与Saroa的技术接触显著增加（p = 0.042），反映了增强的教育价值。结论：RARN和RANU使用Saroa系统是安全可行的，即使在早期临床使用也是如此。该系统的紧凑设计、触觉反馈和成本效益表明，该系统具有广泛采用和培训用途的潜力。需要进一步的前瞻性研究来证实其临床和教育效益。
