Background and ObjectivesWe aimed to examine the effect of preoperative three‐dimensional (3D) computed tomography (CT)‐based resection process map (RPM) imaging on the outcomes of robot‐assisted partial nephrectomy (RAPN).MethodsWe retrospectively analyzed 177 patients (RPM group, n = 92; non‐RPM group, n = 85) who underwent this surgery between November 2012 and April 2022. Patient‐specific contrast‐enhanced CT images were used to construct an RPM, a 3D representation of the kidney showing the planned tumor resection and a 5 mm safety margin. Outcome analyses were performed using propensity score matching. The primary endpoint was the trifecta achievement rate.ResultsWe extracted 90 cases. The trifecta achievement rate showed no significant differences between the RPM (73.3%) and non‐RPM groups (73.3%). However, the RPM group had fewer Grade 3 and higher complications (0.0% vs. 13.3%, p = 0.026). The da Vinci Xi (OR 3.38, p = 0.016) and tumor diameter (OR 0.95, p = 0.013) were independent factors affecting trifecta achievement in multivariate analysis. Using RPM imaging was associated with the absence of Grade 3 and higher perioperative complications (OR 5.33, p = 0.036) in univariate analysis.ConclusionsUsing preoperative 3D CT‐based RPM images before RAPN may not affect trifecta achievement, but may reduce serious complication occurrence by providing detailed information on tumor resection.

基于三维计算机断层扫描的机器人辅助肾部分切除术切除流程图：单中心回顾性研究的倾向评分匹配

背景和目的我们旨在检查术前基于三维（3D）计算机断层扫描（CT）的切除过程图（RPM）成像对机器人辅助肾部分切除术（RAPN）结果的影响。方法我们回顾性分析了 177 名患者（RPM）团体，n= 92；非 RPM 组，n= 85）在 2012 年 11 月至 2022 年 4 月期间接受了这项手术。患者特定的对比增强 CT 图像用于构建 RPM，这是肾脏的 3D 表示，显示计划的肿瘤切除和 5 毫米的安全裕度。使用倾向评分匹配进行结果分析。主要终点是三连胜达成率。结果我们提取了 90 例。RPM 组（73.3%）和非 RPM 组（73.3%）之间的三连胜达成率没有显着差异。然而，RPM 组的 3 级及以上并发症较少（0.0% vs. 13.3%，p= 0.026）。达芬奇习（OR 3.38，p= 0.016）和肿瘤直径（OR 0.95，p= 0.013）是多变量分析中影响三连胜成就的独立因素。使用 RPM 成像与不出现 3 级及以上围手术期并发症相关（OR 5.33，p= 0.036）在单变量分析中。结论在 RAPN 之前使用术前基于 3D CT 的 RPM 图像可能不会影响三连胜的实现，但可以通过提供肿瘤切除的详细信息来减少严重并发症的发生。
