Robotic Partial Nephrectomy and Kidney Surgery
Robotic partial nephrectomy is a minimally invasive operation used to remove a kidney tumour while preserving as much healthy kidney tissue as possible. It is also known as nephron-sparing surgery. The procedure is performed through several small abdominal incisions using robotic instruments controlled entirely by the surgeon. The robotic system provides a magnified three-dimensional view and allows precise dissection, tumour removal and reconstruction of the kidney.
Dr Carlo Bravi offers private consultations in Northampton and London for patients with kidney tumours who are considering robotic partial nephrectomy, require a second opinion or wish to discuss alternative treatment options. Private robotic kidney surgery is undertaken in London.
What Is a Robotic Partial Nephrectomy?
A partial nephrectomy involves removing the kidney tumour together with a small margin of surrounding tissue while leaving the remaining healthy part of the kidney in place. The operation is performed under general anaesthetic. Robotic instruments and a camera are introduced through small incisions in the abdomen. The surgeon identifies the tumour, carefully separates it from the surrounding kidney and reconstructs the remaining kidney tissue.
​
The principal aims are to treat the tumour effectively while preserving kidney function whenever this is oncologically appropriate and technically feasible.
Why Preserve Part of the Kidney?
Whenever suitable, partial nephrectomy allows the tumour to be removed without sacrificing the entire kidney. Preserving healthy kidney tissue may reduce the loss of renal function associated with removing the whole kidney.
​
Current European Association of Urology guidelines recommend partial nephrectomy for patients with T1 kidney tumours when technically feasible. However, the safest and most appropriate operation depends on the tumour’s size, position and complexity, together with the patient’s overall health and kidney function. Preserving the kidney should not compromise safe cancer treatment. In some cases, radical nephrectomy may provide a safer or more appropriate option.
What Happens During the Operation?
Several small incisions are made to allow the robotic camera and surgical instruments to be positioned. The surgeon identifies the kidney and the blood vessels supplying it. Depending on the tumour’s position and the planned technique, blood flow to part or all of the kidney may be temporarily interrupted while the tumour is removed.
​
The tumour is carefully excised with an appropriate margin. Any opening in the kidney’s urine-collecting system is repaired, bleeding vessels are controlled and the remaining kidney tissue is reconstructed using sutures. The removed tumour is placed inside a protective bag and extracted through one of the incisions. A temporary drain or urinary catheter may be used depending on the operation and individual circumstances. The specimen is then examined by a pathologist to determine the type, grade and stage of the tumour and whether the surgical margin is clear.
Potential Benefits of the Robotic Approach
Compared with conventional open surgery, the robotic approach may offer:
-
Smaller abdominal incisions
-
A magnified three-dimensional view of the kidney
-
Precise movement of surgical instruments
-
Reduced blood loss in many patients
-
Less postoperative discomfort
-
A shorter hospital stay, and earlier return to normal activities
The robotic system does not perform the operation independently. Every movement is controlled by the surgeon. These potential benefits do not guarantee a particular outcome. Results depend on the tumour’s characteristics, the patient’s health, the complexity of the operation and the surgical findings.
Benefits and Limitations of Kidney Preservation
The principal advantage of partial nephrectomy is preservation of healthy kidney tissue. This may be particularly valuable for patients who already have impaired kidney function or who may be at risk of developing kidney disease in the future. Partial nephrectomy is technically more complex than removing the whole kidney. It may carry specific risks, including postoperative bleeding and urine leakage from the reconstructed kidney.
​
Occasionally, unexpected findings may mean that completing a partial nephrectomy is not safe. In this situation, conversion to radical nephrectomy may be necessary. This possibility will be discussed before surgery.
When Is Radical Nephrectomy Recommended?
A radical nephrectomy involves removing the entire affected kidney, usually together with the surrounding fatty tissue. The adrenal gland is not routinely removed unless there is a specific clinical reason. Radical nephrectomy may be recommended when:
-
The tumour is too large or complex for safe partial nephrectomy
-
The tumour involves important central structures within the kidney
-
Preserving part of the kidney would compromise cancer control
-
The remaining kidney tissue would be unlikely to function adequately
-
Significant bleeding or another operative difficulty prevents safe completion of a partial nephrectomy
A radical nephrectomy can also be performed using robotic techniques. The decision between partial and radical nephrectomy should balance cancer control, operative safety and preservation of kidney function.
Other Robotic Kidney Procedures
Robotic surgery may also be used for selected other kidney and upper urinary tract procedures. For instance:
​
Robotic Nephroureterectomy
A nephroureterectomy involves removing the kidney, the entire ureter and a small cuff of bladder surrounding the point where the ureter enters the bladder. This operation is most commonly used to treat upper urinary tract urothelial carcinoma, a cancer arising from the lining of the renal pelvis or ureter. The robotic approach can facilitate removal of the kidney and ureter through small incisions while allowing precise reconstruction of the bladder. Treatment planning depends on the tumour’s location, grade and stage, kidney function and whether less extensive treatment may be appropriate. Some lower-risk tumours can be managed with kidney-preserving endoscopic or segmental procedures, whereas nephroureterectomy is generally considered for higher-risk disease.
​
Robotic Pyeloplasty
A pyeloplasty is a reconstructive operation used to treat a narrowing where the renal pelvis joins the ureter, known as pelvi-ureteric junction obstruction. This narrowing can interfere with urine drainage from the kidney and may cause flank pain, recurrent infections, kidney stones or deterioration in kidney function. During robotic pyeloplasty, the narrowed segment is removed and the healthy ureter is reconnected to the renal pelvis to restore drainage. A temporary internal ureteric stent is usually inserted while the new connection heals and is removed at a later date.
​
The most appropriate approach depends on the diagnosis, tumour characteristics, previous surgery and individual anatomy. Not every kidney operation should be performed robotically, and an open or conventional laparoscopic approach may occasionally be safer.
Recovery After Robotic Partial Nephrectomy
The duration of hospital admission varies according to the complexity of the operation and individual recovery. Many patients remain in hospital for approximately one or two nights, although a longer stay may sometimes be required.
Walking is encouraged soon after surgery. Temporary tiredness, abdominal discomfort, bloating and mild bruising around the incisions are common during the early recovery period.
​
Strenuous exercise and heavy lifting should be avoided until your surgeon confirms that it is safe to resume them. Many patients require several weeks before gradually returning to their normal routine. The timing of returning to work depends on the operation, recovery and the physical demands of the job.
​
More precise instructions can only be provided after surgery. Your surgeon will advise you according to how the operation went and your individual progress.
Risks and Possible Complications
Robotic partial nephrectomy is a major operation. Potential risks and complications include:
-
Bleeding or the need for blood transfusion
-
Infection
-
Urine leakage from the reconstructed kidney (urinary fistula)
-
Reduced function of the operated kidney
-
Injury to surrounding organs, blood vessels or other structures
-
Blood clots in the legs or lungs
-
Complications associated with general anaesthesia
-
Incisional hernia
-
Conversion to open surgery and/or radical nephrectomy
-
A positive surgical margin
-
Recurrence of the tumour or the need for further treatment
Rarely, additional radiological or surgical treatment may be required to control bleeding or urine leakage. Your individual risks will be discussed during consultation and again before consent for surgery.
What Happens After the Operation?
The removed tissue is examined under a microscope. The pathology report provides information about whether the tumour is benign or malignant and, when cancer is present, its type, grade, stage and surgical margin. Further treatment is not required for many localised kidney tumours that have been completely removed. Follow-up commonly includes blood tests and imaging, with the schedule determined by the final pathology, kidney function and estimated risk of recurrence.
Patients with more aggressive pathological features may require closer surveillance or referral to a specialist multidisciplinary team to discuss additional treatment.
