目的：研究国产术锐 ® 单孔蛇形臂手术系统行逆行松解神经血管束且保留 Retzius 间隙的优化后入路机器人辅助根 治性前列腺切除术的安全性与可行性，并报道初步经验。方法：收集 2023 年 10 月—2023 年 11 月在天津医科大学第二 医院就诊并接受国产“术锐”单孔蛇形臂机器人辅助根治性前列腺切除术的 3 例患者的临床资料，2 例采用逆行松解神经 血管束且保留 Retzius 间隙的改良后入路，1 例采用前后联合入路，分析患者围手术期资料及随访数据。结果：3 例手术 均顺利完成，自切皮至缝合伤口完毕的手术总时间为 248（217~286）min，其中腔内手术时间为 212（180~255）min， 术中出血量为 306（120~500）mL。3 例患者均未发生术后并发症，切缘均为阴性，其中 2 例实现拔管即刻尿控，1 例实 现拔管 1 周后尿控，术后 1 个月及 12 个月 PSA 均控制良好，未出现生化复发。结论：采用国产术锐 ® 单孔蛇形臂手术 系统可以安全地进行逆行松解神经血管束且保留 Retzius 间隙的优化后入路机器人辅助根治性前列腺切除术，术后短期随 访满意。

Objective: To assess the safety and feasibility of radical prostatectomy via an optimized posterior approach using the domestically developed SHURUI single-port serpentine-arm robotic surgical system, featuring retrograde neurovascular bundle (NVB) release with Retzius-sparing technique, and to report preliminary clinical outcomes. Methods: Clinical data from 3 patients who underwent SHURUI single-port robot-assisted radical prostatectomy at the Second Hospital of Tianjin Medical University from October 2023 to November 2023 were analyzed. 2 patients received the modified posterior approach (retrograde NVB release with Retziussparing), while 1 patient underwent a combined anterior-posterior approach. Perioperative parameters and follow-up data were evaluated. Results: All procedures were successfully completed. Total operative time (from skin incision to wound closure) was 248 (217~286) min, with console time of 212 (180~255) min. Intraoperative bleeding was 306 (120~500) mL. No postoperative complications occurred. Surgical margins were negative in all cases. Immediate urinary continence was achieved in 2 patients after removal of catheter, with 1 patient attaining continence within one week. PSA levels remained well-controlled at 1 and 12 months after surgery, with no biochemical recurrence. Conclusion: The domestically developed SHURUI single-port serpentine-arm robotic surgical system can be used to perform radical prostatectomy via the optimized posterior approach safely incorporating retrograde NVB release and Retzius-sparing techniques, with satisfied short-term follow-up outcomes.
