What is Partial Nephrectomy?

Partial nephrectomy is a surgical procedure that removes only the tumour-bearing portion of the kidney while preserving the remaining healthy kidney tissue. Unlike radical nephrectomy, which removes the entire kidney, this kidney-sparing approach maintains as much functional kidney tissue as possible. The procedure is primarily used to treat small renal masses and localised kidney cancers, though it may also be performed for benign tumours or other kidney conditions.

During partial nephrectomy, the urologist carefully removes the tumour along with a small margin of normal tissue to aim for complete excision. The remaining kidney is then reconstructed to restore its normal anatomy and function. This procedure can be performed via open surgery, laparoscopy, or robot-assisted techniques, depending on tumour location, size, and other patient factors.

Preserving healthy kidney tissue is particularly important for patients with conditions affecting both kidneys, those with only one functioning kidney, and individuals at risk for future kidney problems.

Partial nephrectomy can provide cancer control for appropriate candidates while offering the advantage of preserving kidney function. This preservation may help reduce the risk of chronic kidney disease and its associated complications.

Who is a Suitable Candidate?

Ideal Candidates

Ideal Candidates

  • Patients with small renal masses (typically 4cm or smaller, though tumours up to 7cm may be considered)
  • Individuals with tumours located in positions suitable for partial resection
  • Patients with bilateral kidney tumours requiring treatment of both kidneys
  • Those with a solitary functioning kidney who develop a kidney tumour
  • Individuals with hereditary conditions predisposing to multiple kidney tumours
  • Patients with pre-existing kidney disease or risk factors for kidney dysfunction
  • Younger patients who may benefit from long-term kidney preservation
  • Those with benign kidney tumours causing symptoms or requiring removal
Contraindications

Contraindications

  • Large, centrally located tumours involving major blood vessels
  • Multiple tumours throughout the kidney, making partial removal impractical
  • Severe bleeding disorders that cannot be corrected
  • Active infections requiring treatment before surgery
  • Medical conditions making anaesthesia extremely high-risk
  • Tumours with extensive involvement of the renal hilum (kidney’s blood supply centre)
  • Advanced kidney cancer with metastases (though exceptions may apply)

A thorough evaluation by Dr Azhari is essential to determine if Mini PCNL is appropriate for your specific situation. Your surgeon will consider factors including stone characteristics, kidney anatomy, overall health status, and previous treatment history when recommending the most suitable approach.

Treatment Techniques & Approaches

  • Open Partial Nephrectomy

    Open partial nephrectomy involves making an incision in the flank or abdomen to directly access the kidney. This approach provides visualisation and tactile feedback, allowing the urologist to remove the tumour and reconstruct the kidney. Open surgery may be considered for larger tumours, those in challenging locations, or when other approaches are not suitable. The technique can provide outcomes and remains an option in complex cases.

  • Laparoscopic Partial Nephrectomy

    Laparoscopic partial nephrectomy uses several small incisions through which a camera and instruments are inserted. This minimally invasive approach may offer reduced post-operative pain, shorter hospital stays, and faster recovery compared to open surgery. The procedure requires technical expertise, particularly for complex tumours. Urologists use carbon dioxide gas to create a working space and employ techniques to control bleeding during tumour removal.

  • Robot-Assisted Partial Nephrectomy

    Robot-assisted partial nephrectomy utilises the da Vinci surgical system to perform the procedure through small incisions. The robotic platform provides 3D visualisation, dexterity, and tremor filtration, allowing for tumour excision and kidney reconstruction. This approach has become increasingly used for partial nephrectomy due to its technical advantages in performing tumour removal and kidney repair. The urologist controls the robotic instruments from a console, translating hand movements into surgical actions.

  • Technology & Equipment Used

    Partial nephrectomy employs various technologies to enhance surgical precision and safety. Intraoperative ultrasound helps identify tumour margins and essential kidney structures. Clamps temporarily stop blood flow to minimise bleeding during tumour removal. Energy devices assist with tissue dissection and haemostasis. Some centres use fluorescence imaging to visualise tumours and assess kidney perfusion during surgery.

Wondering which approach might suit you?

Dr Azhari will evaluate your specific needs and discuss the available options.

The Treatment Process

Pre-Treatment Preparation

Before partial nephrectomy, patients undergo a comprehensive evaluation, including blood tests to assess kidney function and overall health. Imaging studies such as CT or MRI scans provide detailed information about tumour size and location. Patients may need to stop certain medications, particularly blood thinners, several days before surgery. Bowel preparation might be required depending on the surgical approach. Patients are instructed to fast from midnight before surgery. Pre-operative anaesthetic assessment aims to optimise patients for the procedure.

During the Procedure

On the day of surgery, patients receive general anaesthesia before the procedure begins. The surgical team positions patients carefully to provide access to the affected kidney. For minimally invasive approaches, the urologist creates small incisions and insufflates the abdomen with carbon dioxide. The kidney is carefully exposed, and the tumour is identified using visual inspection and ultrasound.

The urologist temporarily clamps the kidney’s blood supply to minimise bleeding during tumour removal. The tumour is excised with a margin of normal tissue to aim for complete removal. The remaining kidney defect is then repaired using sutures, and bleeding points are controlled. The blood supply is restored, and the kidney is checked for perfusion. A drain may be placed near the surgical site. The procedure typically takes several hours, depending on complexity.

Immediate Post-Treatment

After surgery, patients recover in the post-anaesthesia care unit where staff monitor vital signs and pain levels. A urinary catheter helps monitor kidney function and urine output. Pain management includes a combination of medications to help maintain comfort. Patients can begin clear liquids once fully awake and progress to a regular diet as tolerated. Early mobilisation, usually within 24 hours, may help prevent complications. The surgical team monitors for any signs of bleeding or other immediate complications.

Recovery & Aftercare

First 24-48 Hours

During the initial recovery period, pain management remains a priority with regular pain assessments and medication adjustments. The urinary catheter typically remains in place to monitor urine output and allow for proper drainage. You’ll be encouraged to perform breathing exercises to prevent pneumonia and begin gentle movement. Blood tests check kidney function and blood counts. Patients can start a regular diet as tolerated. The surgical drain, if placed, is monitored for output and may be removed within a few days if drainage is minimal.

First Week

Hospital discharge typically occurs within a few days after surgery, depending on the surgical approach and the patient’s recovery. At home, you’ll need to limit heavy lifting and strenuous activities while gradually increasing daily walking. Incision care involves keeping the area clean and dry, watching for signs of infection. Pain medication may be progressively reduced as comfort improves. You’ll have a follow-up appointment to check wound healing and review the pathology results. Patients can shower once the incisions are healing well, usually after a few days.

Long-term Recovery

Full recovery generally takes several weeks, with the timeframe varying based on the surgical approach and individual healing. Return to work depends on job requirements, with desk work possible after a few weeks and physical labour requiring a more extended recovery period. Regular activities and exercise can gradually resume based on comfort and urologist guidance. Follow-up imaging may be scheduled to assess the remaining kidney and check for any concerns. Long-term surveillance includes periodic imaging and blood tests to monitor kidney function and check for recurrence.

Benefits of Partial Nephrectomy

Partial nephrectomy may offer advantages for suitable candidates with kidney tumours. The primary potential benefit is preserving kidney function, which becomes increasingly important with age and may help prevent chronic kidney disease. This procedure aims to provide treatment while maintaining quality of life.

Preserving kidney tissue may reduce the risk of long-term complications associated with reduced kidney function, including cardiovascular disease and metabolic problems. For patients with bilateral tumours or genetic conditions predisposing to multiple tumours, kidney preservation may be necessary for maintaining independence from dialysis. The procedure may also provide psychological benefits, as patients might feel reassured knowing they retain kidney reserve.

Minimally invasive approaches may offer additional benefits, including reduced post-operative pain, shorter hospital stays, faster return to normal activities, and improved cosmetic outcomes with smaller incisions. The ability to preserve kidney function while treating cancer represents an advancement in urological surgery, potentially allowing patients to maintain their health and lifestyle after treatment.

Risks & Potential Complications

Common Side Effects

Temporary pain at incision sites is expected and manageable with prescribed medications. Mild blood in the urine (haematuria) commonly occurs for several days after surgery as the kidney heals. Fatigue and weakness are normal during recovery and gradually improve over several weeks. Temporary changes in kidney function may occur, but usually stabilise as the remaining kidney adapts. Constipation from pain medications and reduced activity can be managed with stool softeners and increased fluid intake. These effects typically resolve within the first few weeks after surgery.

Rare Complications

Bleeding requiring transfusion may occur, with severe bleeding requiring additional intervention being uncommon. Urine leakage from the kidney repair site may affect some patients and usually resolves with prolonged drainage. Infection at surgical sites or within the kidney occurs rarely with appropriate antibiotic prophylaxis. Loss of kidney function requiring removal is rare.

Other uncommon complications include blood clots, pneumonia, or injury to surrounding organs. Incomplete tumour removal necessitating additional treatment may occur. The risk of complications is minimised through careful patient selection, meticulous surgical technique, and appropriate post-operative care. Your surgical team may discuss specific risks based on your individual circumstances.

Cost Considerations

The cost of partial nephrectomy in Singapore varies based on several factors, including the surgical approach chosen, with robotic and laparoscopic techniques costing more than open surgery. Hospital stay duration affects overall expenses. The complexity of your specific case, including tumour size and location, influences the time required and the resources needed.

Costs typically include urologist and anaesthetist fees, hospital room charges, operating theatre time, surgical equipment and supplies, post-operative medications, and follow-up care. Additional pathology testing and imaging studies may incur separate charges. Pre-operative assessments and post-operative rehabilitation services can also be considered in overall treatment planning.

Professional care from Dr Azhari aims to provide optimal outcomes and may help reduce the risk of complications requiring additional treatment. During your consultation, you’ll receive a personalised cost estimate based on your specific treatment requirements.

Frequently Asked Questions

How long does partial nephrectomy surgery typically take?

Partial nephrectomy may take several hours depending on the surgical approach and tumour complexity. Robotic and laparoscopic procedures may take longer than open surgery due to the technical steps involved. Factors affecting duration include tumour size, location, and the need for complex reconstruction. Your urologist may provide a more specific timeframe during the pre-operative consultation based on your individual case.

Will I need dialysis after a partial nephrectomy?

Many patients do not require dialysis after a partial nephrectomy. The procedure is designed to preserve kidney function by maintaining healthy kidney tissue. If your other kidney is functioning normally, the remaining kidney tissue may provide adequate function. Your kidney function may be closely monitored after surgery, and your medical team can assess your individual risk based on preoperative kidney function and the amount of tissue removed.

How soon can I return to normal activities after surgery?

Recovery timelines vary depending on the surgical approach used and individual factors. For minimally invasive surgery (laparoscopic or robotic), patients may return to light activities within several weeks and resume full activities over time. Open surgery may require a longer recovery period. Heavy lifting and strenuous exercise should be avoided during the initial recovery period. Your urologist can provide specific guidelines based on your progress and the nature of your usual activities.

What is the success rate for cancer control with partial nephrectomy?

For appropriately selected patients with small kidney tumours, partial nephrectomy may provide cancer control when complete tumour removal with negative margins is achieved. Regular follow-up with imaging helps detect any recurrence early. Your urologist may discuss your specific prognosis based on tumour characteristics and pathology results.

How much kidney function is typically preserved after partial nephrectomy?

Kidney function preservation after partial nephrectomy depends on how much tissue is removed and the quality of the remaining kidney tissue. The other kidney often compensates by increasing its function. Overall, kidney function may remain within normal range, particularly when the opposite kidney is healthy. Function is monitored through regular blood tests during follow-up.

Can kidney tumours come back after partial nephrectomy?

Local recurrence in the operated kidney can occur when the tumour is completely removed with negative margins. New tumours can develop in either kidney, particularly in patients with genetic predispositions. Regular surveillance with imaging and blood tests helps detect any recurrence early, when it’s most treatable. The risk of recurrence depends on various factors, including tumour type, grade, and your individual risk factors.

What follow-up is required after partial nephrectomy?

Follow-up after partial nephrectomy includes regular imaging studies (CT or MRI) to monitor the operated kidney and check for recurrence. Initial imaging may occur at intervals determined by your healthcare team, and ongoing monitoring may be recommended. Blood tests monitor kidney function and overall health. The frequency and duration of follow-up depend on tumour characteristics and your individual risk factors. Long-term surveillance is important for detecting any new tumours early and monitoring kidney function.

Conclusion

Partial nephrectomy represents an established approach in treating kidney tumours whilst preserving kidney function. This kidney-sparing procedure can provide cancer control for suitable candidates whilst maintaining quality of life and may help reduce the risk of long-term kidney-related complications. With various surgical techniques available, from open to robotic-assisted procedures, treatment can be tailored to individual patient needs and tumour characteristics.
