Kangduo (KD) surgical robot is a novel robotic system in China, and some animal experiments and single-arm clinical trials have indicated its effectiveness, feasibility, and safety for urologic surgeries. This study intended to compare the performance and safety of the KD surgical robot with the da Vinci (DV) robotic system in patients who received urologic surgeries.
A total of 201 patients who received urologic surgeries were divided into the KD group (N = 60) and the DV group (N = 141) according to the actual surgical methods.
The median (range) operation time [180.0 (30.0-540.0) minutes vs. 130.0 (70.0-360.0) minutes] (P < 0.001) and indwelling time of abdominal drainage tube [5.0 (2.0-14.0) days vs. 3.0 (2.0-18.0) days] (P < 0.001) were longer, but the intraoperative blood loss [50.0 (10.0-200.0) mL vs. 50.0 (10.0-400.0) mL] (P < 0.001) was less in the KD group than the DV group. The median values of white blood cells at the 1st (P = 0.032) and 3rd (P = 0.022) day after surgery were decreased in the KD group compared to the DV group. The incidence of infection (11.7% vs. 29.1%) (P = 0.008) and fever (15.0% vs. 30.5%) (P = 0.023) was lower in the KD group compared to the DV group. Postoperative and follow-up parameters, including time of urinary incontinence improvement, administration of hemostatic, pain numeric rating scale score, Barthel's index score, and patient satisfaction, were not different between the two groups (all P > 0.05).
The KD surgical robot unveils satisfactory surgical performance compared to the DV robotic system in patients receiving urologic surgeries.
康多（KD）手术机器人是中国一种新型机器人系统，一些动物实验和单臂临床试验已表明其在泌尿外科手术中的有效性、可行性和安全性。本研究旨在比较KD手术机器人与达芬奇（DV）机器人系统在接受泌尿外科手术患者中的性能和安全性。
根据实际手术方式，将201例接受泌尿外科手术的患者分为KD组（N = 60）和DV组（N = 141）。
KD组的中位（范围）手术时间[180.0（30.0 - 540.0）分钟 vs. 130.0（70.0 - 360.0）分钟]（P < 0.001）和腹腔引流管留置时间[5.0（2.0 - 14.0）天 vs. 3.0（2.0 - 18.0）天]（P < 0.001）更长，但术中出血量[50.0（10.0 - 200.0）mL vs. 50.0（10.0 - 400.0）mL]（P < 0.001）比DV组少。与DV组相比，KD组术后第1天（P = 0.032）和第3天（P = 0.022）白细胞的中位数值降低。KD组的感染发生率（11.7% vs. 29.1%）（P = 0.008）和发热发生率（15.0% vs. 30.5%）（P = 0.023）低于DV组。两组术后及随访参数，包括尿失禁改善时间、止血药物使用情况、疼痛数字评分量表得分、巴氏指数评分和患者满意度，均无差异（所有P > 0.05）。
在接受泌尿外科手术患者中，与DV机器人系统相比，KD手术机器人展现出令人满意的手术性能。
