To explore the efficacy of three-dimensional printing physical model-assisted laparoscopic partial nephrectomy (3D-LPN) in patients with renal tumors.
We retrospectively assessed all patients who underwent LPN with or without 3D-printed physical model assistance from January 2016 to February 2018 at our institution. The demographic characteristics, operative findings, and clinical outcomes from the procedure were collected and analyzed.
Sixty-nine patients underwent 3D-LPN and 58 underwent traditional LPN. The groups showed no differences in demographics, RENAL score, surgical approach, operative time, estimated intra-/postoperative blood loss, increased creatinine level, or complications. In the 3D-LPN group, warm ischemia time was shorter, whereas surgery waiting time was longer, compared with those parameters in the LPN group. Subgroup analysis indicated that for patients with RENAL score ≥8, the 3D-LPN group had significantly shorter warm ischemic time and less intraoperative blood loss than the traditional LPN group. Intra- and postoperative hospital complication rates were similar for 3D-LPN and traditional LPN groups (8.7% vs. 13.7%).
3D printing provides an additional tool to assist with LPN. Use of a 3D model can assist in planning and performance of LPN in patients with RENAL score ≥8.
探讨三维打印实体模型辅助腹腔镜肾部分切除术（3D-LPN）治疗肾肿瘤患者的疗效。
我们回顾性评估了2016年1月至2018年2月在我院接受LPN手术（无论是否使用3D打印实体模型辅助）的所有患者。收集并分析了患者的人口统计学特征、手术发现及该手术的临床结果。
69例患者接受了3D-LPN手术，58例接受了传统LPN手术。两组在人口统计学、RENAL评分、手术方式、手术时间、估计的术中/术后失血量、肌酐水平升高或并发症方面无差异。与LPN组相比，3D-LPN组的热缺血时间更短，而手术等待时间更长。亚组分析表明，对于RENAL评分≥8的患者，3D-LPN组的热缺血时间明显短于传统LPN组，术中失血量也更少。3D-LPN组和传统LPN组的术中和术后医院并发症发生率相似（8.7%对13.7%）。
3D打印为LPN提供了一种辅助工具。使用3D模型可协助规划和实施RENAL评分≥8的患者的LPN手术。
