Abstract：
BACKGROUND: No consensus has been reached on operative procedures since a limited case series of robot-assisted inferior vena cava thrombectomy (RA-IVCT) and robot-assisted radical nephrectomy (RA-RN) have been described.
METHODS: The clinical data of 21 patients who underwent RA-IVCT and RA-RN were retrieved from the database. Preoperative preparation was used for assessment of the tumour. Surgical procedures were recorded, and operative skills were summarised.
RESULTS: The median IVC clamping time was 23 min, and IVC wall invasion was pathologically found in 2 cases. The mean postoperative hospital stay was 8.4 days and most patients recovered to full ambulation and oral feeding on the fourth day. None of the patients had liver or kidney dysfunction at the last follow-up (median, 24 months).
CONCLUSIONS: RA-IVCT presents technical challenges to surgeons. IVC control is an important part of the surgical process and different sides require different techniques.

摘要：
背景：由于已经描述了机器人辅助下腔静脉血栓切除术（RA-IVCT）和机器人辅助根治性肾切除术（RA-RN）的有限病例系列，因此尚未就手术程序达成共识。
方法：从数据库中检索21例接受RA-IVCT和RA-RN的患者的临床资料。术前准备用于评估肿瘤。记录外科手术，和操作技能进行了总结。
结果：中位IVC夹持时间为23分钟，2例病理发现IVC壁浸润。术后平均住院时间为8.4天，大多数患者在第四天恢复到完全下床活动和口服喂养。在最后一次随访时，没有患者有肝脏或肾脏功能障碍（中位数，24个月）。
结论：RA-IVCT对外科医生提出了技术挑战。IVC控制是外科手术过程的重要组成部分，不同方面需要不同的技术。
