Inclusion criteria
Inclusion criteria: (1) Patients with level II–III renal tumor and inferior vena cava tumor thrombus, without contraindications to robotic surgery or significant systemic comorbidities; (2) No history of major hepatic surgery, with preserved hepatic functional reserve; (3) Preoperative assessment demonstrating at least one of the following features: large retrohepatic tumor thrombus (diameter >=3.5 cm), dense adhesions around the inferior vena cava, or soft thrombus in the cephalic inferior vena cava.
Exclusion criteria
Exclusion criteria: (1) Contraindications to robotic tumor thrombectomy surgery (e.g., severe cardio/cerebrovascular diseases unfit for anesthesia, poor general condition precluding surgery, widespread tumor metastases making surgery non-beneficial, or other significant systemic diseases); (2) Pre-existing hepatic insufficiency or elevated liver enzymes.
