Objective: To describe the surgical technique for the single port (SP) transperitoneal donor nephrectomy through a modified Pfannenstiel incision using the da Vinci SP surgical system (Intuitive Surgical, Sunnyvale, CA, USA) on a cadaver. Patients & Methods: In a male cadaver, the SP surgical system was used to perform transperitoneal donor nephrectomy. A 3 cm modified Pfannenstiel incision was made. Through the incision GelPOINT mini (Applied Medical, Rancho Santa Margarita, CA, USA) was inserted. The floating docking technique was used. Through the gel port, the dedicated 25 mm multichannel port and a 12 mm assistant port were introduced. The surgical steps for donor nephrectomy were performed in the following order. 1) Mobilization of the colon, 2) Identification of psoas muscle, ureter, and the gonadal vein, 3) hilum dissection, 4) perirenal dissection, 5) stapling the renal artery and renal vein, 6) removal of the kidney through the enlarged incision. Results: Transperitoneal SP donor nephrectomy was completed without any complications or capsulotomy. Additional ports were not needed. The total operative time was 63 minutes and 54 seconds. A good-quality kidney was harvested. Renal artery length was 4 cm. Conclusion: We demonstrated the feasibility of single-port transperitoneal donor nephrectomy via modified Pfannenstiel incision, using the novel SP robotic platform. Further assessment is necessary in a clinical setting.

通过改良的 Pfannenstiel 切口进行单端口供体肾切除术：尸体模型的初步临床前经验和技术描述

目的：描述使用 da Vinci SP 手术系统（Intuitive Surgical，Sunnyvale，CA，USA）在尸体上通过改良的 Pfannenstiel 切口进行单端口 (SP) 经腹膜供体肾切除术的手术技术。患者和方法：在一具男性尸体中，使用 SP 手术系统进行经腹膜供体肾切除术。做了一个 3 cm 改良的 Pfannenstiel 切口。通过切口插入 GelPOINT mini（Applied Medical，Rancho Santa Margarita，CA，USA）。使用了浮动对接技术。通过凝胶端口，引入了专用的 25 mm 多通道端口和 12 mm 辅助端口。供体肾切除术的手术步骤按以下顺序进行。1) 动员结肠，2) 识别腰大肌、输尿管和性腺静脉，3) 肺门解剖，4) 肾周解剖，5) 缝合肾动脉和肾静脉，6) 通过扩大切口取出肾脏。结果：经腹膜 SP 供体肾切除术完成，没有任何并发​​症或囊切开术。不需要额外的端口。总手术时间为63分54秒。收获了一个优质的肾脏。肾动脉长度为 4 cm。结论：我们使用新型 SP 机器人平台证明了通过改良的 Pfannenstiel 切口进行单孔经腹膜供体肾切除术的可行性。在临床环境中需要进一步评估。总手术时间为63分54秒。收获了一个优质的肾脏。肾动脉长度为 4 cm。结论：我们使用新型 SP 机器人平台证明了通过改良的 Pfannenstiel 切口进行单孔经腹膜供体肾切除术的可行性。在临床环境中需要进一步评估。总手术时间为63分54秒。收获了一个优质的肾脏。肾动脉长度为 4 cm。结论：我们使用新型 SP 机器人平台证明了通过改良的 Pfannenstiel 切口进行单孔经腹膜供体肾切除术的可行性。在临床环境中需要进一步评估。
