Locally Advanced RCC
Locally advanced RCC has escaped the kidney locally — into the vein/IVC, perinephric tissues, adrenal or nodes — and surgery is planned around the level of any tumour thrombus.
The big picture
Locally advanced disease means tumour beyond the kidney but without distant metastases: venous tumour thrombus (renal vein → IVC, by level), invasion of perinephric fat or the adrenal, or regional nodes. The thrombus level (renal vein, infrahepatic, retrohepatic, supradiaphragmatic) dictates surgical complexity.
Define the thrombus level before surgery — it determines the approach, the team, and the risk; radical nephrectomy with thrombectomy is the mainstay for resectable disease.

Classification & subtypes
Renal vein
Thrombus confined to the renal vein.
- Why it matters:
- Standard radical nephrectomy with control of the vein.
- Management:
- Radical nephrectomy + thrombectomy.
- Memory hook:
- Level 0/I = renal vein.
- Board trap:
- Missing extension into the IVC.
Infrahepatic IVC
Thrombus in the IVC below the liver.
- Why it matters:
- Needs IVC control below the liver.
- Management:
- Nephrectomy + IVC thrombectomy.
- Memory hook:
- Below the liver.
- Board trap:
- Underestimating vascular control needs.
Retrohepatic IVC
Thrombus behind/at the liver level.
- Why it matters:
- More complex vascular control, possible liver mobilisation.
- Management:
- Specialist vascular planning.
- Memory hook:
- At the liver.
- Board trap:
- Inadequate proximal/distal control.
Supradiaphragmatic / atrial
Thrombus above the diaphragm or into the atrium.
- Why it matters:
- May need cardiopulmonary bypass.
- Management:
- Cardiac surgery collaboration.
- Memory hook:
- Into the chest/atrium.
- Board trap:
- Operating without cardiac backup.
Treatment ladder
Complete surgical resection planned around the thrombus level for resectable disease; systemic therapy for metastatic or selected cases.
Procedure chooser
- Radical nephrectomy with tumour thrombectomy ± node dissection; cardiac/vascular support for high-level thrombus
Follow-up
- Recurrence on imaging
- Renal function
- Caval patency
- Risk-based surveillance schedule
- Complete resection, no recurrence
- Local recurrence or distant metastasis
- Per surveillance; new symptoms
- Recurrence risk; renal function after nephrectomy
Memory hooks
RCC climbs the renal vein into the IVC.
Thrombus level dictates the operation.
New left varicocele → suspect renal vein involvement.
High thrombus may need cardiac bypass.
Board traps
New left-sided varicocele + renal mass — renal vein involvement.
IVC thrombus level not defined preoperatively.
Supradiaphragmatic thrombus operated without bypass capability.
Clinical cases
A man with a large right renal tumour has imaging showing tumour thrombus extending into the retrohepatic IVC.
