Robot-assisted radical nephrectomy with inferior vena cava thrombectomy: a case report

Research output: Contribution to journalArticlepeer-review

Abstract

Background: Recently, robot-assisted surgery has been widely used to treat several urological cancers. Robot-assisted radical nephrectomy (RARN) was approved by the health insurance system in April 2022; however, RARN with inferior vena cava tumor thrombectomy (IVCTT) is still challenging. Also, its safety and feasibility have not yet been established owing to lack of literature, especially in Japan. Case Description: We performed RARN with IVCTT in four patients between April 2022 and March 2023 at Fujita Health University Hospital. To reduce the risk of tumor embolism and major hemorrhage, an "IVC-first, kidney-last" robotic technique was developed. The safety and feasibility of RARN with IVCTT were evaluated by assessing the perioperative outcomes. Three women and one man were enrolled in this study. The median age was 72 years, and the tumor was on the right side in all cases. According to the Mayo Clinic thrombus classification, two patients were classified as level I, and the others were classified as level II. The two patients at level I did not undergo presurgical treatments, whereas the others at level II underwent presurgical treatments, which were combinations of tyrosine kinase inhibitors and immune-checkpoint inhibitors. The median operation and console times were 341 and 247 min, respectively. The median bleeding volume was 577 mL, and no complications beyond grade III of the Clavien-Dindo classification were observed. The median length of postoperative hospital stay was 10 days. Conclusions: Although the sample size was relatively small, we demonstrated the safety and feasibility of RARN with IVCTT in the Japanese population.
