BackgroundRetroperitoneal partial nephrectomy (RLPN) is the premier treatment for localized renal tumors despite narrow operation space. Many efforts have been taken to facilitate the operation of RLPN, but the optimal resolution remains debatable.ObjectiveTo explore the feasibility of using Mini‐lap to improve workspace and surgical vision in RLPN.Design, Setting, and ParticipantsA multicenter retrospective review of 51 patients who underwent RLPN with Mini‐lap from January 2018 to December 2020 was conducted.Surgical ProcedureStandard RLPN under three poles was performed in all cases. We highlighted the usage of Mini‐lap (Teleflex Minilap percutaneous Surgical System) as a novel retractor in RLPN.Outcome and Measurements and Statical AnalysisDemographics, preoperative, intraoperative, and postoperative outcomes were assessed.Results and LimitationsAll 51 cases completed RLPN with three ports successfully and no conversion to open surgery. The mean diameter of tumors was (3.53 ± 1.05) cm, in which 62.7% (32/51) were located anteriorly. The operation time and warm ischemic time (WIT) were (86.7 ± 15.9) min and (25.6 ± 5) min respectively. Minor complications (Clavien grade 1−2) occurred in 6 cases. The limitations were small sample size, retrospective design, and absence of control.ConclusionsMini‐lap could be used as a mini‐retractor in RLPN, sparing extra assistant ports, expanding workspace, and optimizing vision.Patient SummaryWith highlights of larger workspace and less instrument interference, mini‐lap could be applied in retroperitoneal laparoscopic partial nephrectomy.

一种用于后腹膜腹腔镜肾部分切除术的新型微型牵开器

背景尽管手术空间狭窄，腹膜后肾部分切除术（RLPN）仍然是局部肾肿瘤的首选治疗方法。人们已经采取了许多努力来促进 RLPN 的操作，但最佳分辨率仍然存在争议。 目的探讨使用 Mini-lap 改善 RLPN 工作空间和手术视力的可行性。 设计、设置和参与者对 51 例患者进行多中心回顾性评价2018 年 1 月至 2020 年 12 月期间接受了 Mini-lap RLPN。手术程序所有病例均进行三极下的标准 RLPN。我们重点介绍了 Mini-lap（Teleflex Minilap 经皮手术系统）作为 RLPN 中新型牵开器的使用。结果、测量和静态分析对人口统计学、术前、术中和术后结果进行了评估。结果和局限性所有 51 例患者均成功完成了三端口 RLPN并且没有转换为开放手术。肿瘤平均直径为（3.53±1.05）cm，其中62.7%（32/51）位于前方。手术时间和热缺血时间（WIT）分别为（86.7±15.9）min和（25.6±5）min。 6 例发生轻微并发症（Clavien 1~2 级）。局限性在于样本量小、回顾性设计和缺乏控制。结论Mini-lap可以用作RLPN中的微型牵开器，节省额外的辅助端口，扩大工作空间并优化视力。患者总结具有更大的工作空间和更少的仪器的亮点干扰，微型搭接可应用于后腹膜腹腔镜肾部分切除术。
