You have been told that there is a growth on your kidney, the kidney is severely damaged, or it is no longer functioning properly.

The next words you hear can be frightening: nephrectomy surgery.

Patients often immediately ask, “Can I live with one kidney?” The answer is yes, many people can live healthy lives with one functioning kidney. But whether removing a kidney is appropriate depends on the underlying condition, the health of the other kidney, and the overall medical picture.

What Is Nephrectomy Surgery?

Nephrectomy is a surgical procedure in which part or all of a kidney is removed.

There are different types of nephrectomy, and the choice depends on why surgery is needed.

Main Specialties

Our main kidney surgery specialties include:

  • Partial nephrectomy

  • Radical nephrectomy

  • Kidney tumour evaluation

  • Kidney cancer surgery

  • Severely damaged kidney management

  • Non-functioning kidney assessment

  • Pre-operative kidney evaluation

  • Post-operative kidney monitoring

  • Follow-up of remaining kidney function

The goal is not simply to remove a kidney. It is to treat the underlying problem while preserving as much healthy kidney function as reasonably possible.

When Is Nephrectomy Recommended?

A Kidney Tumour Needs Treatment

One of the important reasons for nephrectomy is a kidney tumour, particularly when cancer is suspected or confirmed.

Depending on the size, location and characteristics of the tumour, the surgeon may recommend removing only the affected portion of the kidney or the entire kidney.

That decision requires detailed imaging and medical assessment.

The Kidney Is Severely Damaged

A kidney that has been badly damaged by disease, repeated infection, obstruction or another condition may sometimes need to be removed.

But removal is not automatically the answer. Doctors first need to understand how much the affected kidney is functioning and whether surgery is actually necessary.

One Kidney Is Causing Serious Problems

In selected cases, a poorly functioning kidney may contribute to repeated infections, bleeding, severe complications or other significant problems.

The treatment depends on the underlying cause. Surgery is considered when the expected benefit outweighs the risks.

Partial or Complete Removal?

Partial Nephrectomy

A partial nephrectomy removes only the diseased portion of the kidney while preserving the remaining healthy tissue.

This approach may be considered for certain kidney tumours or other localized problems when preserving kidney tissue is medically appropriate.

Radical Nephrectomy

A radical nephrectomy involves removing the entire affected kidney.

It may be recommended for certain larger or more complex kidney tumours or other conditions where preserving the kidney is not considered appropriate.

The choice between partial and radical nephrectomy is individualized.

Can You Live With One Kidney?

Yes.

Many people live normal, active lives with one healthy functioning kidney. However, having one kidney means protecting its health becomes especially important.

Regular blood pressure checks, appropriate blood and urine testing, healthy lifestyle habits and medical follow-up can help monitor kidney function.

Your doctor may also advise you about medicines, hydration, diet and other factors depending on your individual condition.

Don't Assume More Surgery Means Better Treatment

Here is the contrarian point patients should know: removing the whole kidney is not automatically better than preserving part of it.

When medically suitable, preserving healthy kidney tissue can be valuable.

For some patients, partial nephrectomy may allow the diseased portion to be removed while retaining functioning kidney tissue. But partial surgery is not appropriate for every tumour or every patient.

The right question is not, “Which surgery sounds smaller?”

It is, “Which procedure gives this patient the safest and most appropriate treatment while protecting long-term kidney function?”

What Symptoms May Lead to Investigation?

Kidney tumours and other conditions requiring nephrectomy do not always cause obvious symptoms.

Depending on the underlying problem, patients may experience:

  • Blood in urine

  • Persistent pain in the side or back

  • An unexplained lump or mass

  • Unexplained weight loss

  • Persistent tiredness

  • Fever without an obvious cause

  • Repeated urinary problems

However, some kidney tumours are discovered incidentally during an ultrasound or scan performed for another reason.

That is why a finding on imaging should be properly evaluated rather than automatically assumed to be cancer.

A Real-World Patient Situation

Imagine a patient undergoing an abdominal scan for an unrelated complaint. The scan unexpectedly identifies a small mass in one kidney.

The patient is understandably frightened and immediately assumes the entire kidney must be removed.

Further imaging and specialist assessment show that the mass is localized and that kidney-preserving surgery may be considered.

The final treatment depends on the patient's specific anatomy and medical findings, but the example highlights an important lesson: the first scan is the beginning of the evaluation, not necessarily the final treatment decision.

A 2024–2025 Kidney Cancer Perspective

Recent International Agency for Research on Cancer data show that kidney cancer occurs in India across both men and women, with cancer registries including New Delhi reporting kidney cancer cases. The available registry data also show higher incidence rates among men than women in New Delhi.

This does not mean every kidney mass is cancerous. Many kidney findings require careful imaging and specialist assessment before their nature can be determined.

What Happens Before Surgery?

Imaging Comes First

Doctors may use imaging such as ultrasound, CT or MRI to understand the size, position and characteristics of a kidney lesion.

The choice of scan depends on the patient's condition and what the doctor needs to determine.

Kidney Function Matters

Before surgery, the medical team also needs to know how well both kidneys are functioning.

Blood tests and other evaluations help determine whether the remaining kidney is likely to provide adequate function after surgery.

This is particularly important when the patient already has chronic kidney disease or other health problems.

What Happens After Nephrectomy?

Your Remaining Kidney Matters

After complete removal of one kidney, the remaining kidney takes on the work of filtering waste from the blood.

Most people with a healthy remaining kidney can live without dialysis after nephrectomy. However, regular medical monitoring remains important.

Blood pressure, kidney function and urine findings may need to be checked periodically.

Recovery Takes Time

Recovery depends on the type of surgery, the patient's health and whether the procedure was open or minimally invasive.

Your surgical team will provide specific instructions about activity, wound care, medicines, diet and follow-up.

Dr. D.K. Agarwal: Why Experience Matters

Look at the Whole Kidney Picture

Dr. D.K. Agarwal is a name patients may consider when seeking experienced kidney-focused medical guidance. Before major kidney surgery, careful assessment matters because the treatment decision must consider the kidney lesion, kidney function, the health of the opposite kidney and the patient's overall medical condition.

What Should You Ask Before Nephrectomy?

If surgery has been recommended, don't hesitate to ask direct questions.

Consider asking:

  • Why is nephrectomy necessary?

  • Is partial nephrectomy possible?

  • What happens if the whole kidney is removed?

  • How well is my other kidney functioning?

  • What are the risks of surgery?

  • What type of surgical approach is being recommended?

  • How long might recovery take?

  • What follow-up will I need afterward?

Understanding the reason for surgery can make the decision much less frightening.

Frequently Asked Questions

1. Can you live normally after kidney removal?

Many people can live healthy and active lives with one functioning kidney. However, protecting the remaining kidney through appropriate medical follow-up is important.

2. Is partial nephrectomy better than complete kidney removal?

Not necessarily for every patient. Partial nephrectomy can preserve healthy kidney tissue when it is medically appropriate, but the safest option depends on the size, location and nature of the kidney problem and the patient's overall health.

3. Does every kidney tumour require kidney removal?

No. Kidney tumours require individual assessment. Imaging and other investigations help doctors determine the nature and extent of the lesion and the most appropriate treatment.

Don't Make the Decision Based on Fear

Hearing that you may need kidney surgery can make you imagine the worst immediately.

Instead, focus on understanding the actual problem: why surgery has been recommended, whether kidney-preserving treatment is possible, how well the other kidney works, and what recovery will involve.

If you have been advised to consider nephrectomy, take your imaging reports and previous kidney tests to a qualified specialist and discuss all medically appropriate treatment options before making a decision.
