Using a new robotic endoscopic platform system developed for retrograde intrarenal surgery (RIRS) called easyUretero (ROEN Surgical Inc.), we evaluated the feasibility and safety of renal stone retrieval in a porcine model.
Six female pigs were used for our in vivo study. First, 0.3-cm-sized phantom stones were inserted into the kidneys of each pig via the ureteral access sheath. Next, renal stone retrieval was attempted using manual RIRS in three pigs and robotic RIRS in three pigs. Three surgeons performed extraction of 10 stones in each session.
The mean stone retrieval time by manual RIRS was significantly shorter than that by robotic RIRS (399.9±185.4 sec vs. 1127.6±374.5 sec, =0.001). In contrast, the questionnaire regarding usability showed high satisfaction in the surgeons' fatigue category for surgeons using robotic RIRS. The radiation exposure dose was also lower in robotic RIRS than in manual RIRS (0.14 µSv vs. 45.5 µSv). Postoperative ureteral injury assessment revealed Grade 0 in manual RIRS cases and Grades 0, 1, and 2 in robotic RIRS cases.
The easyUretero system is a new robotic RIRS system that was developed in Korea. The results of the present study suggest that using easyUretero for stone retrieval during RIRS is safe and ergonomic.
我们使用一种名为 easyUretero（ROEN Surgical Inc.）的新型逆行肾盂内手术（RIRS）用机器人内窥镜平台系统，评估在猪模型中经皮肾镜取石术（PCNL）取石的可行性和安全性。
本研究共纳入 6 头雌性猪。首先，通过输尿管鞘将 0.3cm 大小的模拟结石插入每头猪的肾脏内。然后，分别采用手动 RIRS 和机器人 RIRS 尝试取石。每次手术有 3 名外科医生尝试取出 10 个结石。
手动 RIRS 的平均取石时间明显短于机器人 RIRS（399.9±185.4 秒 vs. 1127.6±374.5 秒，=0.001）。然而，在外科医生的疲劳程度方面，对于使用机器人 RIRS 的外科医生，其易用性问卷显示出高度满意度。与手动 RIRS 相比，机器人 RIRS 的辐射暴露剂量也较低（0.14µSv vs. 45.5µSv）。术后输尿管损伤评估显示，手动 RIRS 组均为 0 级，机器人 RIRS 组分别为 0、1 和 2 级。
easyUretero 系统是一种新型的韩国研发的机器人 RIRS 系统。本研究结果表明，使用 easyUretero 进行 RIRS 取石是安全且符合人体工程学的。
