Partial Nephrectomy: A Surgical Procedure to Remove Part of the Kidney
Introduction to Partial Nephrectomy
A partial nephrectomy is a surgical procedure designed to remove a part of the kidney, preserving as much healthy tissue as possible. This operation is commonly performed when a localized tumor is present within the kidney. The procedure can be carried out through open surgery or a minimally invasive laparoscopic approach, often aided by robotic technology. Minimally invasive surgery typically involves less pain and a quicker recovery compared to traditional methods.
Why Choose Partial Nephrectomy?
Also referred to as nephron-sparing surgery, the goal of a partial nephrectomy is to remove only the tumor or damaged portion of the kidney while maintaining healthy tissue. The nephron, the kidney’s filtering unit, is essential for waste elimination. By preserving a sufficient number of nephrons, the kidney can continue to function properly.
For tumors smaller than 7 cm (3 inches), partial nephrectomy can remove the affected tissue while leaving the rest of the kidney intact. This method is often chosen when the tumor has not spread to the lymph nodes or other organs. In some cases, even larger tumors may be removed if complete kidney removal is not a feasible option, such as for individuals with only one functioning kidney.
The Surgical Procedure: What to Expect
During a partial nephrectomy, the procedure is carried out under general anesthesia in a sterile surgical suite. If laparoscopic surgery is used, the surgeon will make small incisions to insert thin instruments, including a camera, to view and remove the tumor. Blood flow to the affected area is temporarily reduced to minimize blood loss. The tumor is carefully excised, and the remaining kidney tissue is sutured. This method may also be performed with robotic assistance, allowing for greater precision and smaller incisions.
If an open surgery is necessary, a larger incision is made along the side, and in some cases, a rib may need to be removed to access the kidney.
Benefits of Laparoscopic vs. Open Surgery
Laparoscopic (keyhole) surgery offers several advantages over open surgery, including:
-
Enhanced visualization due to magnification
-
Reduced pain and faster recovery
-
Shorter hospital stays and less need for blood transfusions
-
Lower risk of infection and fewer incisional hernias
-
The ability to preserve more kidney function
A 2020 study showed that survival rates for cancer patients, as well as disease-free survival and recurrence rates, were comparable for both laparoscopic and open partial nephrectomies. However, following your surgeon’s instructions is crucial to avoid post-surgery complications.
Recovery and Post-Operative Care
After laparoscopic surgery, most patients remain in the hospital for about two days. Initially, you will have a urinary catheter and a drain, both of which are removed a few days post-surgery. On the first day, you will begin eating light foods, such as soups, and drink plenty of fluids. After discharge, you can gradually return to a normal diet. Pain management is typically handled with an analgesic pump, allowing you to control the level of medication that keeps you comfortable. For most people, Tylenol (acetaminophen) will suffice after the initial recovery period.
If you undergo open surgery, the recovery time is longer, with hospital stays potentially lasting up to a week. The incision may take up to three months to fully heal, and it can take several weeks to regain full strength. During recovery, you should avoid strenuous activities, including lifting heavy objects, until cleared by your medical team.
Potential Complications
As with any major surgery, partial nephrectomy carries the risk of complications, including:
-
Bleeding during or after surgery
-
Urinary fistula (leakage of urine into the abdomen)
-
Infections, blood clots, or pneumonia
-
Difficulty with healing at the surgical site
Contact your healthcare provider if you experience any of the following symptoms:
-
Fever or chills
-
Difficulty breathing
-
Swelling or tenderness in your calf or thigh
-
Blood in your urine
-
Redness or pus near the incision site
Pathology Results and Follow-Up Care
After the surgery, it typically takes about a week for the pathology results to come back, which will detail the nature of the tumor and whether cancer cells were present in the removed tissue. Your doctor will discuss the findings with you and outline any further treatment, if necessary.
Follow-up visits will be scheduled, typically within a month of surgery, and then at the 12- and 24-month marks, to ensure your kidney continues to function well and to monitor for signs of disease recurrence.
Conclusion
Partial nephrectomy offers a valuable option for treating kidney tumors while preserving kidney function. Whether performed through a minimally invasive laparoscopic approach or traditional open surgery, the goal is to remove the tumor with as little disruption to the healthy kidney tissue as possible. Discussing your options with your healthcare team will help ensure the best possible outcome for your condition.
