Robotic radical nephrectomy

Who it suits

• Tumours > cT1b that cannot be resected with a clear margin while preserving useful kidney function.
• Central or hilar tumours that involve the renal artery and vein.
• Selected tumours with extension into the renal vein or inferior vena cava (level I-II, in experienced centres), where the dexterity of the robot assists the caval dissection.
• Tumours with regional lymph node involvement where lymphadenectomy is planned.

What the operation involves

1. Positioning in a flank position; ports placed; robot docked.
2. The colon is reflected medially to expose the kidney and the great vessels.
3. The renal artery and vein are dissected, clipped and divided.
4. The ureter is identified and divided.
5. The kidney, together with its surrounding fat and Gerota fascia, is freed en bloc.
6. Regional lymphadenectomy is added in selected cases.
7. The adrenal gland is preserved unless there is specific concern about adrenal involvement.
8. The specimen is placed in a bag and removed through an extended port incision. The abdominal wall is closed in layers.

Complex cases

In experienced hands, robotic access is suitable for selected T3 tumours with venous extension, hilar lymph node disease, or previous abdominal surgery. More advanced caval extension (level III-IV) is generally still performed open or via a combined approach. The decision is individualised and made after full staging imaging.

Hospital stay

Typical stay is two to three nights for straightforward cases, longer for cases with lymphadenectomy or venous involvement. Recovery to full activity over four to six weeks.

Expected outcomes

• Oncologic control is equivalent to laparoscopic and open radical nephrectomy for comparable disease.⁷
• Blood loss and transfusion rates are lower than open surgery.⁴
• The remaining kidney compensates over months; most patients with a normal contralateral kidney maintain acceptable renal function.

Potential complications

• Bleeding, occasionally requiring transfusion or conversion to open surgery.
• Injury to adjacent structures (bowel, spleen, liver, pancreas, pleura), uncommon.
• Wound issues at the specimen extraction site.
• Chronic kidney disease progression if the remaining kidney is impaired.
• Standard risks of abdominal surgery.

Alternatives

• Partial nephrectomy when feasible - see robotic partial nephrectomy.
• Open radical nephrectomy for very large or centrally advanced tumours.
• Systemic therapy first in selected metastatic cases, often with a multidisciplinary plan.
