Being diagnosed with a kidney tumour does not automatically mean that the entire kidney needs to be removed.
For many patients with localized kidney cancer, partial nephrectomy—removing the tumour while preserving the remaining healthy kidney—is an important treatment option.
However, partial nephrectomy is not suitable for every tumour.
The decision between partial nephrectomy and radical nephrectomy depends on several factors:
The aim is not simply to remove less kidney.
The aim is:
Cancer Control + Kidney Preservation + Surgical Safety + Long-Term Renal Function
Partial nephrectomy is an operation in which the kidney tumour is removed while the remaining healthy kidney tissue is preserved.
It is also called:
For appropriately selected localized kidney tumours, partial nephrectomy can provide cancer control while preserving more functioning kidney tissue.
The operation may be performed through:
The choice of approach depends on the tumour, the patient’s anatomy, the complexity of the operation and the experience of the surgical team.
Radical nephrectomy means removal of the entire affected kidney.
Depending on the individual case, the operation may also involve removal of surrounding tissues and other structures when clinically indicated.
Radical nephrectomy may be recommended when:
For some advanced tumours, particularly when there is major involvement of the renal vein or inferior vena cava, a more extensive operation may be required.
Partial Nephrectomy | Radical Nephrectomy | |
What is removed? | Tumour + a margin of surrounding kidney tissue | Entire affected kidney |
Main objective | Remove tumour while preserving functioning kidney | Remove the entire affected kidney |
Kidney tissue preserved? | Yes | No functioning tissue from that kidney remains |
Suitable for | Selected tumours where safe complete removal is feasible | Tumours where kidney preservation is not technically or oncologically appropriate |
Renal function | More kidney tissue is preserved | Remaining kidney must provide renal function |
Surgical complexity | Can be technically demanding, particularly for complex tumours | May be more straightforward in some tumours, but can also be complex for advanced disease |
The choice should be individualized rather than based on tumour size alone.
No.
Preserving the kidney is important, but kidney preservation should not come at the expense of cancer control or surgical safety.
A tumour may be relatively small but located:
Conversely, a larger tumour may occasionally be technically suitable for partial nephrectomy in a carefully selected patient.
Therefore:
Tumour size is important—but tumour anatomy and complexity are equally important.
The objective is to choose the operation that provides the best balance between complete tumour removal, preservation of useful kidney tissue and surgical safety.
Partial nephrectomy is generally considered when the tumour can be completely removed while leaving an adequate amount of functioning kidney.
It is particularly relevant for localized kidney tumours.
The decision may be influenced by:
Smaller tumours are often more amenable to kidney-preserving surgery, although size alone does not determine feasibility.
A tumour on the outer surface of the kidney may be technically different from one located deep within the kidney.
An endophytic tumour—one that grows predominantly within the kidney—may be more technically challenging than an exophytic tumour projecting outward.
Tumours close to the renal artery, renal vein or hilar structures require careful planning.
A tumour close to the urine-collecting system may require careful reconstruction after tumour removal.
The amount and quality of kidney tissue that can safely be preserved are important considerations.
Pre-existing kidney disease or reduced renal function can make preservation of functioning renal tissue particularly important.
If a patient has only one functioning kidney, or has tumours affecting both kidneys, kidney preservation becomes especially important when technically possible.
Radical nephrectomy may be recommended when partial nephrectomy cannot provide an appropriate balance of cancer control and safety.
Examples include tumours that:
In these situations, attempting to preserve the kidney is not necessarily the safer or better cancer operation.
The right operation is the one that safely achieves the required cancer treatment while considering the patient’s long-term renal function.
Not by itself.
For example:
A 3 cm tumour may be suitable for partial nephrectomy.
But if it is deeply endophytic and closely related to the renal hilum and collecting system, the operation may be technically demanding.
A larger tumour may sometimes still be considered for partial nephrectomy in selected patients if adequate healthy kidney can be preserved safely.
With increasing tumour size and local extent, radical nephrectomy may become more appropriate, particularly when kidney preservation would compromise safe and complete tumour removal.
This is why the CT/MRI anatomy of the tumour is more informative than the size written on the report alone.
Before deciding between partial and radical nephrectomy, the imaging is reviewed carefully.
Important questions include:
In complex tumours, a nephrometry system such as RENAL or PADUA scoring may also help describe anatomical complexity.
However, these scores support clinical decision-making; they do not replace individualized surgical assessment.
This is one of the situations where kidney preservation can become particularly important.
A patient may have a solitary functioning kidney because:
If a tumour develops in a solitary kidney, partial nephrectomy may be considered when technically feasible because preserving functioning renal tissue can reduce the risk of severe loss of kidney function.
The operation can, however, be technically demanding and requires careful planning.
Bilateral kidney tumours require an individualized strategy.
Depending on the tumour characteristics, treatment may involve:
The objective is to achieve appropriate cancer treatment while preserving as much useful renal function as safely possible.
Yes.
The kidneys perform important functions including:
Removing an entire kidney does not mean that a patient cannot live a normal life. Many people live well with one functioning kidney.
However, preserving functioning renal tissue can be particularly valuable in patients with:
Therefore, kidney preservation is an important consideration—but only when it can be achieved safely.
For appropriately selected localized kidney cancers, partial nephrectomy can provide effective cancer control while preserving more renal tissue.
The key phrase is:
“Appropriately selected.”
Partial nephrectomy should not be performed simply because preserving the kidney sounds preferable.
The tumour must be completely removable with an acceptable surgical risk and adequate remaining functioning kidney.
Current evidence and international guidance support partial nephrectomy for appropriately selected localized renal tumours, particularly T1 tumours.
When partial nephrectomy is appropriate, it can be performed using a robotic approach in selected patients.
Robotic surgery provides a minimally invasive platform that can assist with:
However, robotic surgery does not make every tumour suitable for partial nephrectomy.
The decision to preserve the kidney comes first.
The choice of robotic, laparoscopic or open surgery comes after considering the tumour and the safest way to perform the required operation.
Some tumours are straightforward to remove.
Others require much more detailed surgical planning.
Examples include:
In such cases, the surgeon must plan not only how to remove the tumour, but also:
How much functioning kidney can be safely preserved?
The detailed surgical steps involved in optimizing renal preservation are discussed separately.
My approach is based on four principles:
The tumour must be completely and appropriately treated.
If a meaningful amount of functioning kidney can be safely preserved, nephron-sparing surgery is considered.
The operation should be performed with an acceptable risk based on tumour anatomy and the patient’s overall condition.
The patient’s current and future kidney function are considered—not just the immediate operation.
I do not decide between partial and radical nephrectomy based on tumour size alone.
I review the imaging, tumour anatomy, renal function and overall clinical situation before recommending the operation.
I have undergone dedicated uro-oncology training during my surgical oncology training, including training in kidney cancer surgery and complex renal tumours.
I have been performing robotic surgery since 2013 and have performed 100+ robotic kidney operations.
My kidney cancer practice includes:
The appropriate operation is selected according to the individual tumour rather than using one surgical approach for every patient.
Selected videos, Google reviews and anonymised case summaries from Dr Swati Shah’s kidney cancer practice, shared for patient education. Every patient’s plan is individual, and a past case does not predict an individual result. For the full overview see kidney cancer surgery in Ahmedabad by Dr Swati Shah.
A partial nephrectomy removes the tumour while preserving as much normal kidney as possible. This kidney-sparing approach can help maintain better kidney function compared with removing the entire kidney in appropriately selected patients.
Preserving kidney function is important because reduced kidney function can increase the risk of chronic kidney disease (CKD) and may also be associated with cardiovascular problems. Maintaining healthy kidney function can therefore contribute to better overall health and potentially better long-term outcomes.
Importantly, for appropriately selected localized kidney tumours, partial nephrectomy can provide excellent cancer control without a higher risk of cancer recurrence compared with radical nephrectomy.
The objective of surgery is not simply to remove the visible tumour, but to achieve complete oncological clearance with negative surgical margins. Careful dissection is performed around the kidney and major blood vessels to safely control the renal artery and vein while minimizing the risk of tumour spillage or injury to surrounding organs.
The removed specimen is then sent for detailed histopathological examination. This confirms the exact tumour type and provides important information about tumour size, grade, stage, margins and other pathological features that help determine the need for further treatment and surveillance.
For a large or locally advanced renal tumour, the surgical approach must be carefully planned based on the CT findings, tumour location, vascular involvement and the patient’s overall health.
Robotic systems provide a magnified, high-definition view of the surgical field along with highly flexible instruments that can make precise movements in confined spaces. This can help the surgeon accurately identify the tumour and surrounding healthy kidney tissue.
During a robotic partial nephrectomy, the goal is to remove the tumour completely while preserving as much healthy kidney tissue as possible. Another important consideration is the duration for which the kidney’s blood supply needs to be temporarily controlled during tumour removal and reconstruction.
Efficient and precise surgery can help reduce this period of temporary interruption of blood flow, which may contribute to better preservation of kidney function.
He expresses immense gratitude and satisfaction, highlighting a crucial aspect of the surgery: Dr. Shah successfully removed only the cancerous portion of the kidney, preserving the healthy half. This advanced partial nephrectomy approach saved his mother’s vital kidney function, and the family is extremely happy with the excellent medical care they received at the hospital. She herself also speaks in the video, expressing her heartfelt relief and joy. She confirms that the robotic procedure went smoothly and emphasizes how perfectly the complex surgery was handled.
The YouTube video features an inspiring patient testimonial highlighting a successful robotic partial nephrectomy for a kidney tumor, performed by Dr. Swati Shah, a specialized Robotic Uro Oncologist, alongside Dr. Harsh. In the clip, the patient and his son share their immensely positive experience with the surgical team and the hospital. The patient expresses profound satisfaction with the procedure, noting that his recovery has been so remarkably smooth that he barely feels like he underwent a major surgery at all. In fact, within just ten days post-operation, he recovered completely and was fit enough to independently drive his family back to the hospital for his follow-up visit. The son shares this deep gratitude, emphasizing his father’s rapid return to fitness right from the moment he regained consciousness.
This video features a heartfelt testimonial, a patient who underwent a highly specialized Robotic Radical Nephrectomy for recurrent kidney cancer under the expert care of Dr. Swati Shah.

The choice between partial and radical nephrectomy rests on tumour anatomy (for example the RENAL nephrometry score), baseline kidney function (eGFR), whether negative surgical margins can be achieved and how long the kidney needs to be clamped. The two cases below show how these factors were weighed when the kidney was preserved.
The tumour lay in a kidney with three renal arteries, one renal vein and inflammatory adhesions at the hilum. It was removed with a circumferential margin and renorrhaphy; warm ischaemia (clamp) time was 25 minutes, blood loss about 200 ml, and no transfusion was needed. The aim was to preserve functioning kidney and reduce long-term risk of chronic kidney disease.
A 62-year-old woman had a 5.3 cm upper-pole left renal mass found on screening. Using the Da Vinci Xi system, the hilum was isolated, the blood supply selectively clamped and the tumour excised with blood loss of about 300 ml. Pathology showed pT1b clear cell carcinoma with negative resection margins and preserved baseline renal function.

Before deciding between partial and radical nephrectomy, consider asking:
Once the surgical approach has been selected, the next discussion usually involves:
Understand whether a small renal mass requires treatment and when surveillance, biopsy or treatment may be considered.
Understand how robotic kidney-sparing surgery is performed and where robotic surgery may be useful.
Understand the technical factors involved in tumour excision, reconstruction and preservation of functioning kidney.
Understand how larger and more locally extensive kidney tumours are evaluated and treated.
Understand kidney cancer involving the renal vein or inferior vena cava and the surgical considerations involved.
No. Partial nephrectomy is preferred when it can safely provide appropriate cancer control while preserving useful kidney tissue. Some tumours are better treated by radical nephrectomy.
No. Tumour size is important, but location, depth, vascular involvement, collecting-system relationship and the amount of kidney that can be safely preserved also matter.
In selected patients, partial nephrectomy may be technically feasible. The decision depends on the tumour’s anatomy and the amount of functioning kidney that can be preserved.
No. Partial nephrectomy can be performed through open, laparoscopic or robotic approaches. The safest approach depends on the individual tumour and surgical expertise.
Yes. It involves removal of the entire affected kidney and is a major cancer operation, although many patients live well with one functioning kidney.
Many people can live well with one functioning kidney. However, preserving kidney function may still be important, particularly in patients with existing kidney disease or other factors that increase future renal risk.
Bilateral kidney tumours require individualized planning. Kidney-preserving surgery may be considered when technically feasible.
This may require a more complex surgical plan. Tumour thrombus involving the renal vein or IVC is a separate clinical situation and is discussed in detail on the dedicated page.
This page provides general information about partial and radical nephrectomy.
The appropriate operation cannot be determined from tumour size alone or from an online description.
The decision should be based on the patient’s imaging, tumour anatomy, kidney function, overall health and the feasibility of achieving complete cancer treatment safely.
Cancer control remains the first priority. When oncologically and technically appropriate, kidney-preserving surgery can help preserve functioning renal tissue and support long-term kidney health.
