盆腔淋巴结清扫术（PLND）对于前列腺癌和/或膀胱癌的准确分期和预后非常重要。一些指南建议对这些癌症患者进行延长 PLND。然而，延长 PLND 的治疗益处尚不清楚。主要原因之一是PLND的范围没有明确界定。因此，日本腔内泌尿外科和机器人学会于 2023 年 1 月成立了机器人辅助 PLND 标准化工作组，其中包括日本 9 名经验丰富的 PLND 泌尿科医生。本研究总结了这些经验丰富的泌尿科医生在共识会议上定义泌尿外科 PLND 个体范围的讨论。共识会议根据动脉（静脉）和解剖膜结构确定 PLND 的范围，而不是模糊的 PLND 概念或方法。这一概念预计将使外科医生能够实施相同程度的 PLND。最后，经过总共10次在线网络会议，我们根据以下公式确定了闭孔淋巴结（LN）区、髂内淋巴结区、髂外淋巴结区和髂总淋巴结区以及骶前淋巴结区的PLND范围。上述规则。此处建议的 PLND 范围目前尚无明确的治疗原理。因此，我们提出的 PLND 范围绝不是强制性的。我们希望我们对 PLND 范围的定义能够得到泌尿系统癌症治疗益处的进一步证据的支持。© 2024 日本泌尿外科协会。

Pelvic lymph node dissection (PLND) is important for accurate staging and prognosis of prostate and/or bladder cancer. Several guidelines recommend extended PLND for patients with these cancers. However, the therapeutic benefits of extended PLND are unclear. One major reason is that the extent of PLND is not clearly defined. Thus, the working group for standardization of robot-assisted PLND, including nine experienced urologists for PLND in Japan, was launched in January 2023 by the Japanese Society of Endourology and Robotics. This study summarized the discussions to define the individual extent of PLND in urological surgery in a consensus meeting among these experienced urologists. The consensus meeting determined the extent of PLND based on arteries (veins) and anatomical membrane structures rather than a vague concept or approach toward PLND. This concept is expected to allow surgeons to implement the same extent of PLND. Finally, after a total of 10 online web conferences were held, we determined the extent of PLND for the obturator lymph node (LN) area, the internal iliac LN area, the external and common iliac LN area, and the presacral LN area according to the above rules. The extent of PLND suggested here currently does not have a clear therapeutic rationale. Therefore, the extent of our proposed PLND is by no means mandatory. We hope our definition of the extent of PLND will be supported by further evidence of therapeutic benefits for urologic cancers.© 2024 The Japanese Urological Association.
