Robotic Partial Nephrectomy Mumbai | Robotic Kidney Preservation Surgery for Kidney Cancer

The majority of kidney tumors today are detected incidentally when scans are done for other reasons. This allows detection of tumors at a relatively small size and early stage.

Partial Nephrectomy is a surgery where only the tumor is removed, leaving the rest of the kidney intact in order to preserve renal function.

This achieves excellent cancer control which is equivalent to removing the entire kidney.

It can be done by an open incision or via a minimally invasive Robotic Partial Nephrectomy approach.

Surgery is the best treatment for kidney cancers, especially those in an early stage.

Partial nephrectomy is considered the gold standard treatment for many kidney tumors smaller than 4 cm. In selected cases, it may also be the preferred approach for larger tumors up to 7 cm, especially when the tumor is favourably located, technically removable, and enough healthy kidney tissue can be preserved.

In patients with pre-existing renal failure, tumors in both kidneys, or tumor in a solitary kidney, every attempt is made to perform a Partial Nephrectomy irrespective of tumor size and difficulty.

Patients who have diseases like diabetes or hypertension, which can affect the kidney, also benefit from Partial Nephrectomy for Kidney Cancer if technically possible.

Suspicious cysts, especially Type III and Type IV cysts, can be cancerous and are best removed.

Not every kidney tumor requires removal of the entire kidney.

Advances in surgical techniques have made Kidney Preservation Surgery possible for many patients.

Several factors influence whether a Partial Nephrectomy can be performed:

Tumor Size

Smaller tumors are often excellent candidates for kidney-sparing treatment.

Tumor Location

Tumors located near the outer surface of the kidney are generally easier to remove while preserving healthy tissue.

Tumor Complexity

The depth and relationship of the tumor to blood vessels and collecting systems influence surgical planning.

Kidney Function

Preserving healthy kidney tissue becomes especially important in patients with reduced baseline kidney function.

Overall Health

Age, medical history, and other health conditions contribute to treatment decisions.

The goal is to remove the cancer completely while preserving as much functioning kidney tissue as possible.

Historically, many kidney tumors were treated by removing the entire kidney.

While this remains appropriate in selected situations, preserving healthy kidney tissue whenever possible offers important long-term advantages.

Benefits of Kidney Preservation Surgery may include:

• Better long-term kidney function
• Lower risk of chronic kidney disease
• Preservation of overall health
• Protection against future kidney-related complications and possible dialysis
• Greater reserve if future kidney problems develop

This is particularly important for:

• Patients with diabetes
• Patients with hypertension
• Elderly individuals
• Patients with a solitary kidney
• Patients with pre-existing kidney disease

The modern emphasis on nephron preservation reflects the growing understanding that kidney function plays a vital role in long-term health and wellbeing.

ne of the most technically demanding aspects of Partial Nephrectomy involves managing the kidney's blood supply during tumor removal.

The kidneys receive a rich blood supply, making precise surgical planning essential.

During surgery:

• Blood flow may be temporarily controlled
• The tumor is carefully excised
• The kidney is reconstructed
• Blood flow is restored

A key objective is minimizing the period during which blood supply is interrupted.

This helps protect healthy kidney tissue and preserve long-term kidney function.

Advanced robotic technology allows surgeons to perform these delicate steps with exceptional precision.

Successful management of this phase is an important factor influencing both cancer control and postoperative kidney performance.

Many patients assume that complex kidney tumors automatically require removal of the entire kidney.

However, advances in imaging, surgical planning, and robotic technology have expanded the range of tumors that can be treated through Partial Nephrectomy.

In selected cases, kidney preservation may still be possible for:

• Deeply located tumors
• Larger tumors
• Tumors near major blood vessels
• Tumors near the collecting system
• Complex anatomical locations

Every case requires individualized assessment.

The decision depends on balancing cancer control, surgical safety, and preservation of kidney function.

Careful preoperative planning plays a critical role in determining the feasibility of kidney-sparing surgery.

After your imaging and staging tests such as CT scan or MRI, you will discuss your options with your urologist.

Important discussion points include:

• The need for Partial Nephrectomy or Radical Nephrectomy
• Whether you are a candidate for a robotic procedure
• The chances that you may need a Radical Nephrectomy even if Partial Nephrectomy is planned
• What further treatments might be needed

To proceed with surgery, the general instructions include:

• Basic blood and urine tests to assess fitness for surgery
• Cardiac evaluation like ECG and 2D Echo
• Stopping blood-thinning medication for 5–7 days before surgery
• Anesthesia check-up and assessment
• Healthy diet and exercise until the surgery
• Admission the day prior or day of surgery

After surgery, patients can usually expect:

• Resumption of a liquid diet within 6–8 hours after surgery
• Normal food from the next day
• Getting out of bed and walking a few hours after surgery
• Mild pain after robotic surgery, easily controlled with medications
• Stronger painkillers may be needed after open surgery
• Urinary catheter to drain the bladder for 1-2 days
• Abdominal drain, usually removed in 2-3 days
• Hospital discharge in 3–4 days
• Longer hospital stay may be needed after open surgery
• Return to work in about 2–3 weeks

Patients can walk as much as they like, but strenuous activities such as lifting weights, golfing, gym workouts, and similar activities should be avoided for one month after surgery.

Every surgery carries a risk of complications.

General complications may include:

• Anesthesia-related problems
• Infection
• Blood clots
• Deep vein thrombosis
• Pneumonia
• Cardiac events

In addition, certain specific complications include:

Bleeding

The kidney receives about 20% of the blood pumped out from the heart and is a very vascular organ.

Bleeding is a risk in these surgeries, and transfusion may be required.

In Partial Nephrectomy, cutting through the kidney to remove the tumor can cause bleeding.

Very rarely, in less than 1% of cases, this may appear after 3–4 weeks as a pseudoaneurysm or fistula.

Delay in the Recovery of Intestinal Function

This is also called ileus.

It can happen after more extensive surgeries and may sometimes take up to a week to resolve.

Urine Leak

If a part of the kidney that drains urine, such as the calyx or pelvis, has been cut during Partial Nephrectomy, urine may leak into the space around the kidney.

This generally settles by itself but rarely may need insertion of a drain or stent.

Need for Radical Nephrectomy

If the tumor is more advanced than expected on the scan, or if there is bleeding that is difficult to control, the surgeon may need to perform a Radical Nephrectomy for safety.

Postoperative Precautions

Patients should remain vigilant during the first month of recovery. While rare, occurring in only 0.5% to 1% of cases, there is a risk of delayed bleeding. Immediate medical attention is required if you experience symptoms such as severe flank pain, blood in the urine (hematuria), or fainting (syncope), as these may indicate a pseudoaneurysm requiring angiography to stop the bleeding.

Robotic Surgery provides significant benefits for both patient and surgeon.

Advantages of Robotic Partial Nephrectomy include:

• Smaller incisions with less pain and scarring
• Shorter hospital stay and quick return to normal activities
• Reduced bleeding and blood transfusion rates
• Lower risk for wound infection
• Shorter ischemia time than laparoscopy and equal to open surgery, resulting in less kidney damage
• Excellent magnified view allowing precise closure of blood vessels and collecting system in the tumor bed
• Precise closure of the remaining kidney
• Much more ergonomic than laparoscopy

Every kidney tumor presents unique anatomical and surgical challenges.

Recovery after Robotic Partial Nephrectomy is generally faster than traditional open surgery, although individual experiences vary.

Following surgery, patients are encouraged to:

• Walk early
• Stay hydrated
• Follow postoperative instructions
• Attend scheduled follow-up appointments

Monitoring may include:

• Kidney function tests
• Imaging studies
• Clinical evaluations
• Cancer surveillance

Long-term follow-up helps ensure both continued kidney health and successful cancer control.

Most patients gradually return to normal daily activities over the weeks following surgery.

The cost of partial nephrectomy typically ranges between 5 to 10 lakhs. Please note that this cost is indicative and can vary based on several factors, including the choice of hospital, room category, and the complexity of the surgery.
