Direct Answer

Kidney cancer surgery (nephrectomy) is the surgical treatment of localised renal tumours. According to European Association of Urology (EAU) guidelines, it is performed using one of two approaches: partial nephrectomy (kidney-sparing) or radical nephrectomy (removal of the entire kidney). Surgical techniques include open, laparoscopic, and robotic surgery.

What Is Kidney Cancer Surgery?

Kidney cancer surgery is the surgical removal of malignant tumours identified in the kidney.

Also known as renal cell carcinoma (RCC), kidney cancer accounts for the vast majority of renal tumours in adults. Surgery is the primary treatment with curative potential for localised kidney cancer.

Kidney tumour surgery is performed using two main techniques. Partial nephrectomy — also referred to as kidney-sparing surgery — involves removing the tumour along with a margin of healthy surrounding tissue, while preserving the remaining kidney. This approach is preferred particularly for small renal tumours (stage T1a and T1b). Radical nephrectomy involves removal of the entire kidney together with the surrounding fatty tissue and, where indicated, the adrenal gland.

Kidney cancer surgery can today be performed using open, laparoscopic, or robotic techniques. Robotic kidney surgery offers significant advantages in terms of precise dissection and kidney preservation, particularly in partial nephrectomy. The choice of surgical technique is determined by tumour size, location, the patient’s general condition, and the surgeon’s experience.

According to European Association of Urology (EAU) guidelines, partial nephrectomy should be performed wherever possible for renal tumours smaller than 7 cm (stage T1). This approach is critically important for the long-term preservation of kidney function. Prior to surgery, detailed staging assessment is carried out using computed tomography (CT) or magnetic resonance imaging (MRI).

Who Is a Candidate?

Kidney cancer surgery is used to treat renal masses identified on imaging. The decision to operate is made following assessment of the tumour’s characteristics, the patient’s general health, and individual factors.

The main indications for kidney cancer surgery are: solid renal masses with features suspicious for malignancy on imaging, biopsy-confirmed kidney cancer, renal masses that are growing or symptomatic, and patients for whom active surveillance is not appropriate. Surgical treatment is considered the priority approach for suspicious masses identified in young and otherwise healthy patients.

Partial nephrectomy (kidney-sparing surgery) is preferred in the following situations: tumours smaller than 7 cm (stage T1), solitary kidney, bilateral (both-sided) renal tumours, individuals with chronic kidney disease, and hereditary kidney cancer syndromes. Radical nephrectomy is indicated for large tumours (generally over 7 cm), tumours that are anatomically unsuitable for partial nephrectomy, and locally advanced disease.

Treatment planning is determined through a multidisciplinary approach, with each patient’s case assessed individually. During your consultation with Prof. Dr. Özkan Onuk, tumour characteristics, surgical options, and expected outcomes will be discussed in detail.

Who Is Not a Candidate?

Kidney cancer surgery cannot be performed in certain situations, and alternative treatment approaches may be preferred. Surgical contraindications are classified as absolute or relative.

Absolute contraindications include uncorrectable coagulopathy (clotting disorders), uncontrolled severe infection, and patients unfit for general anaesthesia. In cases of widespread metastatic disease, the benefit of surgery may be limited and systemic therapies take priority.

Relative contraindications include: elderly patients with significant co-morbidities, severe cardiopulmonary disease, patients at high surgical risk, and individuals with limited life expectancy. In these patients, alternative approaches such as active surveillance, ablation therapies (radiofrequency ablation, cryoablation), or stereotactic radiotherapy may be considered.

For small renal tumours — particularly those under 4 cm — active surveillance may be appropriate in elderly patients or those with significant co-existing conditions. In this approach, the tumour is monitored with regular imaging, and treatment planning is reassessed if growth or change is observed.

Each patient’s case is addressed individually, and the most appropriate treatment approach is determined following multidisciplinary evaluation.

Comparison of Surgical Approaches

Kidney cancer surgery can be performed using three different surgical approaches. Each technique has its own advantages and disadvantages.

Feature Open Surgery
Traditional		 Laparoscopic
Minimally Invasive		 Robotic Surgery
Advanced Technology
Incision Size 15–20 cm 3–4 small incisions (0.5–1 cm) 4–5 small incisions (0.5–1 cm)
Surgery Duration 2–3 hours 2–4 hours 2–4 hours
Blood Loss Greater Less Less
Hospital Stay 5–7 days 2–4 days 2–4 days
Recovery Time 6–8 weeks 3–4 weeks 3–4 weeks
Pain Level High Low–moderate Low–moderate
Partial Nephrectomy Feasible Technically challenging Ideal
Visualisation Direct view 2D camera 3D HD imaging

Open surgery is preferred for large or complex tumours, cases involving venous involvement, or situations where minimally invasive surgery is not appropriate. The surgeon can directly palpate the tissue and benefits from a wide operative field.

Laparoscopic surgery is widely used, particularly for radical nephrectomy. Smaller incisions reduce post-operative pain and accelerate recovery. However, in partial nephrectomy, the technical demands of the approach require considerable surgical experience.

Robotic surgery is the preferred approach, especially for partial nephrectomy. Three-dimensional visualisation, high magnification, and 360-degree instrument articulation enable precise dissection and reconstruction. Ischaemia time (the period during which blood flow to the kidney is interrupted) can be minimised, which offers a significant advantage for preserving kidney function.

The choice of surgical technique is determined by tumour characteristics, the patient’s anatomy and general condition, the surgeon’s experience, and the available technological infrastructure.

Expectations and Outcomes

Outcomes following kidney cancer surgery vary according to tumour stage, surgical approach, and the patient’s general condition. Setting realistic expectations is an important part of the treatment process.

For localised kidney cancer (stage T1–T2), surgical treatment achieves high cure rates. Oncological outcomes following surgery for early-stage tumours are very favourable, and the majority of patients achieve long-term disease-free survival. In locally advanced disease (stage T3–T4), prognosis varies depending on tumour characteristics and surgical margin status.

Preserving kidney function after partial nephrectomy is one of the primary goals of surgery. Following a successful partial nephrectomy, the remaining kidney tissue continues to function normally, and the long-term risk of chronic kidney disease is reduced. After radical nephrectomy, life with a single kidney is possible; where the contralateral kidney is healthy, compensatory mechanisms take over.

Regular follow-up after surgery is an integral part of kidney cancer management. The follow-up protocol includes imaging studies (CT, MRI), blood tests, and physical examination. The frequency and duration of follow-up are determined by the tumour’s risk classification. Less frequent intervals are sufficient for low-risk tumours, while high-risk patients require more intensive and longer-term surveillance.

Individual outcomes may vary. During your consultation with Prof. Dr. Özkan Onuk, expectations specific to your situation will be discussed in detail.

How Is the Surgery Performed?

A thorough preparation process takes place before kidney cancer surgery. Pre-operative assessment includes review of imaging studies, blood tests, cardiological evaluation, and anaesthetic consultation. Patients must fast from midnight before the procedure, and any blood-thinning medications must be stopped a specified number of days in advance.

On the day of surgery, the patient is placed under general anaesthesia. For robotic or laparoscopic surgery, the patient is positioned in a lateral decubitus (side-lying) position, and trocars are inserted through small incisions in the abdominal wall. The abdominal cavity is insufflated with carbon dioxide gas to create the working space.

In partial nephrectomy, the surgical procedure involves the following steps: mobilisation of the kidney and identification of its vessels; localisation of the tumour under ultrasound guidance; clamping of the renal artery (ischaemia); excision of the tumour with a clear surgical margin; repair of the collecting system; suturing of the renal parenchyma; and achievement of haemostasis. Minimising ischaemia time is critically important for preserving kidney function.

In radical nephrectomy, the renal vessels are ligated, the kidney is mobilised together with the surrounding tissue, and removed within an endoscopic specimen bag. Regional lymph nodes are also removed where indicated.

At the end of the procedure, the incisions are closed and the patient is transferred to intensive care or a surgical ward. The removed tissue is sent for pathological examination to confirm the definitive diagnosis and staging.

Risks and Complications

As with any surgical procedure, kidney cancer surgery carries certain risks. Complication rates are related to the surgeon’s experience, the technique selected, and the patient’s general condition.

Complication Frequency Notes
Bleeding Rare May require blood transfusion or reoperation
Infection Rare Wound site or urinary tract infection
Urinary leakage Rare (partial) Related to collecting system injury
Loss of kidney function Variable Transient or permanent, depending on ischaemia time
Adjacent organ injury Very rare Spleen, bowel, pancreas, liver
Thromboembolic events Rare Deep vein thrombosis, pulmonary embolism
Conversion to open surgery Rare In cases commenced with a minimally invasive approach

Complications specific to partial nephrectomy include urinary leakage (urinoma), post-operative bleeding, arteriovenous fistula, and pseudoaneurysm. Most of these complications can be managed with conservative treatment or minimally invasive interventions.

To reduce the risk of complications, the following are important: pre-operative optimisation (nutritional status, management of co-existing conditions), performance of the procedure by an experienced surgeon and team, appropriate patient selection, and close post-operative monitoring.

Possible complications and individual risk factors are discussed in detail during the consultation.

Recovery

Recovery following kidney cancer surgery varies according to the surgical technique chosen and the patient’s general condition. Recovery with minimally invasive approaches is faster compared to open surgery.

First 24–48 hours (In hospital): The patient is monitored closely in intensive care or a surgical ward. Pain management, fluid balance monitoring, early mobilisation, and breathing exercises are important elements of this period. A urinary catheter and any surgical drains are in place and removed according to clinical progress.

First week (After discharge): Light walking is encouraged. Heavy lifting and strenuous activity are not permitted. Wound care instructions must be followed and prescribed medications taken regularly. A high-fibre diet and adequate fluid intake are recommended to prevent constipation.

Weeks 2–4: Daily activities are gradually increased. Driving is generally possible after 2–3 weeks. Return to desk-based work can be planned during this period. An outpatient appointment is scheduled for wound review.

Weeks 4–6: Return to normal activities is complete. Physically demanding work and sport can be resumed during this period. Pathology results are reviewed and a follow-up plan is established.

Long-term follow-up: Regular reviews are the cornerstone of kidney cancer management. Reviews include imaging studies, kidney function tests, and physical examination. The follow-up protocol is individualised according to the tumour’s risk classification.

If any concerns arise during recovery — such as fever, severe pain, wound discharge, or inability to urinate — contact your doctor promptly.

Frequently Asked Questions

Kidney Cancer Surgery — Frequently Asked Questions

The most common questions about kidney cancer surgery, answered.

Surgery duration varies according to the technique chosen and the tumour's characteristics. Partial nephrectomy typically takes 2–3 hours; radical nephrectomy 1.5–3 hours. With robotic and laparoscopic approaches, the total time may be slightly longer due to system set-up.
This decision is based on tumour size, location, and the patient's general condition. For tumours smaller than 7 cm, partial nephrectomy (removal of the tumour only) is preferred wherever possible. Radical nephrectomy may be necessary for larger tumours or those in anatomically challenging positions.
Yes, a normal life is possible with a single kidney. The remaining kidney increases its function through compensatory mechanisms. However, regular follow-up, adequate fluid intake, and a kidney-friendly lifestyle are recommended to protect kidney function long-term.
With minimally invasive (robotic or laparoscopic) surgery, hospital stay is generally 2–4 days; with open surgery, approximately 5–7 days. Discharge timing may vary depending on the patient's general condition and post-operative progress.
Post-operative pain is significantly less with minimally invasive techniques compared to open surgery. Appropriate analgesics are provided for pain management, and the majority of patients find the pain tolerable.
Those in desk-based roles can generally return to work within 2–4 weeks. For physically demanding work, this may extend to 6–8 weeks. Return timing varies according to individual recovery speed and the nature of the work.
For localised kidney cancer, recurrence rates after surgery depend on tumour stage. Recurrence is uncommon in early-stage tumours, while the risk increases with more advanced disease. This is why a regular follow-up programme is critically important.
Robotic surgery offers specific advantages in partial nephrectomy: precise dissection, shorter ischaemia time, and reduced blood loss. However, the most appropriate technique for each case is determined following individual assessment.
In most cases, imaging findings (CT, MRI) are sufficient for diagnosis and a biopsy is not required. Biopsy is recommended in specific situations: diagnostic uncertainty, when active surveillance is planned, prior to ablation therapy, or before systemic treatment in metastatic disease.
Adjuvant (additional) treatment is generally not required following surgery for localised kidney cancer. However, for high-risk patients — such as those with large tumours, lymph node involvement, or positive surgical margins — immunotherapy or targeted therapies may be considered. Each patient is assessed individually.
