Radical nephrectomy is surgery to remove the entire kidney containing a tumour. It is used when a kidney cancer is too large, centrally located, locally advanced or technically unsuitable for safe kidney-sparing surgery, and in some cases where preserving part of the kidney would not provide a meaningful functional benefit. The operation removes the kidney and surrounding fatty tissue; the adrenal gland or lymph nodes are removed only when clinically indicated. Many people live normally with one healthy kidney, but kidney function should be assessed before and after surgery.

When is radical nephrectomy recommended?

The decision is based on tumour stage, size, location, the condition of both kidneys and overall health. Radical nephrectomy is commonly considered for T2 or larger tumours and for masses where partial nephrectomy would be unsafe or oncologically inappropriate.

A large tumour does not automatically mean the cancer has spread, and a small tumour does not automatically require partial nephrectomy. The actual images and expected remaining kidney function matter.

What exactly is removed?

• The affected kidney
• Perinephric fat within the surgical envelope
• Part or all of the ureter only when required for a specific diagnosis
• Adrenal gland only if suspicious or directly involved
• Regional lymph nodes when enlarged or when nodal assessment is clinically useful

Open, laparoscopic or robotic approach

Many radical nephrectomies can be performed laparoscopically or robotically, which generally means smaller incisions and quicker early recovery. Open surgery remains important for very large tumours, major venous tumour thrombus, extensive local involvement or situations where direct access is safer.

Main risks

• Bleeding, infection and blood clots
• Injury to bowel, spleen, liver, pancreas or major blood vessels depending on side and anatomy
• Reduced overall kidney function
• Anaesthesia-related complications
• Hernia or wound problems after open surgery
• Need for additional treatment if pathology shows high-risk or metastatic disease

Living with one kidney

Before surgery, the team estimates how well the opposite kidney functions. After nephrectomy, creatinine and eGFR are monitored. Most people with a healthy remaining kidney do not require a special “kidney diet,” but blood pressure control, diabetes control, avoiding unnecessary kidney-toxic medicines and periodic renal function testing are sensible.

Why a whole-kidney operation may be the kidney-preserving decision overall

If a complex tumour can only be partially removed at the cost of major bleeding, prolonged reconstruction or leaving very little useful parenchyma, radical nephrectomy can be the safer oncological operation. The decision is strongest when the opposite kidney functions well. Conversely, a solitary kidney or significant chronic kidney disease raises the threshold for removing the entire organ.

The adrenal gland is not automatically part of the operation

Older descriptions of radical nephrectomy often implied routine adrenal removal. Modern surgery generally preserves the adrenal when imaging and operative findings do not suggest direct involvement, particularly for tumours away from the upper pole. Lymph-node dissection is also selective rather than automatically extensive in every localised renal mass.

Before accepting nephrectomy, clarify renal reserve

• Current creatinine and eGFR
• Whether the other kidney is structurally normal
• Diabetes, hypertension or proteinuria that may affect future kidney health
• Whether partial nephrectomy is technically unreasonable or simply more difficult
• Whether systemic therapy is relevant based on stage rather than assumed after surgery

What should be clear before removing the whole kidney

The reason for radical rather than partial nephrectomy should be specific: tumour size alone is not enough. Important reasons include central/hilar anatomy, extensive sinus or venous involvement, very little salvageable parenchyma, or a situation in which partial nephrectomy would create disproportionate risk. Baseline eGFR, the opposite kidney and future kidney-disease risk should be reviewed before surgery because those factors determine how consequential loss of one kidney may be.

When to seek earlier medical review

After nephrectomy, contact the team if pain or abdominal distension is worsening, fever develops, the wound becomes red or draining, urine output falls, or breathlessness/calf swelling occurs. Kidney function should also be reviewed if you become dehydrated or start potentially nephrotoxic medicines.

What to bring to your consultation

• CT/MRI images and report
• Creatinine/eGFR and opposite-kidney information
• Diabetes/BP records if relevant
• Previous biopsy/pathology if performed

Questions to ask your doctor

• Why is partial nephrectomy not appropriate in my case?
• Is the adrenal gland expected to be removed?
• What kidney-function change should I expect after surgery?
