Partial Nephrectomy in Singapore | Kidney Cancer Treatment

Open partial nephrectomy involves making an incision in the flank or abdomen to directly access the kidney. This traditional approach provides visualisation and tactile feedback, allowing precise tumour removal. The surgeon can directly control bleeding and repair the kidney after tumour excision. Open surgery remains valuable for complex tumours or when minimally invasive approaches are not suitable.

Laparoscopic partial nephrectomy uses several small incisions through which a camera and specialised instruments are inserted. This minimally invasive technique offers reduced post-operative pain, shorter hospital stays, and faster recovery compared to open surgery. The procedure requires specialised expertise but provides positive outcomes for appropriately selected tumours.

Robot-assisted partial nephrectomy utilises the da Vinci surgical system, providing enhanced 3D visualisation and precise instrument control. The robotic platform offers improved dexterity for complex reconstructions and may reduce warm ischaemia time (the period when kidney blood flow is temporarily stopped). This technique has become increasingly popular for its precision and favourable outcomes.

Modern partial nephrectomy employs various technologies including intraoperative ultrasound for tumour localisation, specialised clamps for temporary blood flow control, and established suturing techniques for kidney reconstruction. Some centres use fluorescence imaging to better visualise tumour margins and ensure complete excision.

Before partial nephrectomy, patients undergo comprehensive evaluation including blood tests to assess kidney function, urine analysis, and imaging studies (CT or MRI) to precisely locate the tumour. Patients may need to stop certain medications, particularly blood thinners, several days before surgery. Fasting is required from midnight before the procedure. Pre-operative antibiotics are administered to prevent infection. Some patients may need to complete bowel preparation depending on the surgical approach planned.

The procedure begins with general anaesthesia administration. For open surgery, the surgeon makes an incision to access the kidney. In minimally invasive approaches, several small incisions are made for instrument insertion. The surgeon carefully mobilises the kidney and identifies the tumour using visual inspection and ultrasound.

The renal blood vessels may be temporarily clamped to minimise bleeding during tumour removal. The surgeon excises the tumour with a margin of healthy tissue, then reconstructs the kidney defect with sutures. Haemostasis (bleeding control) is achieved before closing the surgical site. The entire procedure typically takes 2-4 hours depending on complexity.

After surgery, patients recover in the post-anaesthesia care unit with close monitoring of vital signs and urine output. A urinary catheter remains in place to monitor kidney function and ensure proper drainage. Pain management begins immediately with a combination of medications. Most patients can begin clear liquids once fully awake and advance their diet as tolerated. Early mobilisation is encouraged to prevent complications.

During the initial recovery period, patients receive intravenous fluids and pain medications. The surgical team monitors kidney function through blood tests and urine output measurements. The urinary catheter typically remains for 1-2 days. Patients begin walking with assistance within 24 hours. Breathing exercises help prevent pneumonia. Clear liquids progress to regular diet as tolerated. Hospital discharge usually occurs within 2-4 days for minimally invasive surgery or 3-5 days for open surgery.

At home, patients should maintain adequate hydration to support kidney function. Pain typically improves significantly, transitioning from stronger medications to over-the-counter options. Activity restrictions include no heavy lifting (over 5kg) and avoiding strenuous activities. Incision care involves keeping wounds clean and dry. Patients should monitor for signs of infection including fever, increased pain, or unusual drainage. A follow-up appointment is scheduled within 7-10 days for wound check and pathology results discussion.

Full recovery typically takes 4-6 weeks for minimally invasive approaches and 6-8 weeks for open surgery. Patients gradually increase activity levels, returning to normal exercise after surgeon clearance. Regular follow-up includes imaging studies (CT or MRI) at 3-6 months post-surgery, then periodically based on pathology results. Kidney function tests monitor the remaining kidney tissue. Most patients experience no long-term limitations, though maintaining kidney health through proper hydration and regular monitoring remains important.

Temporary side effects after partial nephrectomy include pain at the incision sites, which typically responds well to prescribed medications. Mild blood in the urine (haematuria) may occur for several days post-surgery but usually resolves spontaneously. Fatigue is common during the first few weeks of recovery. Some patients experience temporary changes in kidney function that normalise as the remaining kidney adapts. Constipation from pain medications can be managed with stool softeners and adequate hydration.

Less common but potential complications include bleeding requiring transfusion or additional intervention, occurring in approximately 2-5% of cases. Urine leakage from the reconstructed kidney may require temporary drainage. Infection at surgical sites or in the urinary system requires antibiotic treatment. Very rarely, kidney function may be compromised enough to require further intervention. Blood clots, though uncommon, are prevented through early mobilisation and sometimes blood thinners.

These risks are minimised through careful surgical technique, appropriate patient selection, and experienced surgical teams. MOH-accredited urologists employ established protocols to prevent complications and manage them promptly if they occur.
