What is a Robotic Partial Nephrectomy?
A robotic partial nephrectomy is a surgical procedure used to remove a kidney tumour while preserving the rest of the kidney.
Instead of removing the entire kidney, only the tumour and a small margin of surrounding healthy tissue are removed. This helps maintain as much normal kidney function as possible.
The operation is performed using robotic-assisted keyhole (minimally invasive) surgery, which allows the surgeon to operate with high precision through small incisions.
Robotic Partial Nephrectomy
Why is this Procedure Performed?
Robotic partial nephrectomy is commonly recommended for:
Small kidney tumours (usually less than 4–5 cm)
Tumours located in areas where part of the kidney can be safely preserved
Patients where preserving kidney function is important
Some larger or more complex kidney tumours in selected cases
Preserving kidney tissue helps reduce the risk of long-term kidney problems.
How is the Procedure Performed?
The operation is performed under general anaesthetic, meaning you will be asleep during the procedure.
During the surgery:
Several small incisions are made in the abdomen.
Robotic surgical instruments and a camera are inserted through these small openings.
The surgeon controls the robotic instruments from a nearby console.
The blood supply to the kidney may be temporarily controlled.
The tumour is carefully removed while preserving healthy kidney tissue.
The remaining kidney tissue is repaired.
The procedure usually takes 2–4 hours, depending on the complexity of the tumour.
Advantages of Robotic Surgery
Robotic-assisted surgery offers several benefits compared with traditional open surgery, including:
Smaller incisions
Less blood loss
Reduced pain after surgery
Shorter hospital stay
Faster recovery
Better preservation of kidney function
Hospital Stay and Recovery
Most patients stay in hospital for 1-3 days after surgery.
During recovery you may experience:
Mild abdominal discomfort
Temporary fatigue
Small dressings over the incision sites
Most patients can return to normal activities within 3–4 weeks, although heavy lifting should be avoided for several weeks.
Possible Risks and Complications
As with any surgery, there are potential risks, including:
Bleeding
Infection
Urine leakage from the kidney repair
Injury to surrounding organs (rare)
Need to convert to removal of the entire kidney if necessary
Blood clots
Your surgeon will discuss these risks with you before the procedure.
Pathology Results
The removed tumour is sent to a laboratory where a specialist pathologist examines it.
The results will determine:
Whether the tumour is cancerous
The type of kidney cancer
The grade and stage of the tumour
Results are usually available within 1–2 weeks.
Kidney Function After Surgery
Most patients maintain good kidney function after partial nephrectomy because much of the kidney is preserved.
The remaining kidney tissue continues to perform normal kidney functions.
Follow-Up
Regular follow-up is important after kidney tumour surgery.
Follow-up may include:
Imaging scans (CT or ultrasound)
Blood tests to monitor kidney function
Clinical review with your surgeon
The follow-up schedule depends on the type and stage of the tumour.
When to Seek Medical Attention
Contact your doctor if you experience:
Fever or signs of infection
Severe pain
Persistent nausea or vomiting
Heavy bleeding from the wound
Difficulty passing urine
