Comparison of Open and Robot Assisted Radical Nephrectomy With Level I and II Inferior Vena Cava Tumor Thrombus: The Mayo Clinic Experience

摘要

OBJECTIVE To compare the perioperative and oncologic outcomes associated with open radical nephrectomy with tumor thrombus (O-RNTT) vs robot assisted radical nephrectomy with tumor thrombus (RA-RNTT). Renal cell carcinoma with venous tumor thrombus has traditionally been managed through an open surgical approach. The robot assisted approach may offers improved perioperative outcomes compared to open, but there are few studies comparing these 2.
