Introduction
A nephrectomy is a major surgical procedure that involves the partial or complete removal of a kidney. Kidneys are bean-shaped organs located in the back of the abdomen that filter waste and excess fluid from the blood to produce urine. There are two main types of nephrectomy: a partial nephrectomy removes only the diseased or damaged portion of a kidney, preserving as much healthy tissue as possible, while a radical (or total) nephrectomy removes the entire kidney, along with the attached section of the ureter, the surrounding fat, and sometimes the adrenal gland. This surgery is most commonly performed to treat kidney cancer or to remove a severely damaged, non-functioning kidney resulting from infection, disease, or trauma. It is also the procedure used to harvest a healthy kidney from a living donor for transplantation.

Surgical Procedure
Nephrectomies can be performed using open surgery or minimally invasive techniques (laparoscopic or robotic-assisted).
In an open nephrectomy, the surgeon makes a single large incision in the abdomen or the side (flank). The muscle and tissue are separated to access the kidney. The blood vessels and ureter connected to the kidney are clamped and cut, and the kidney (or a portion of it) is removed.
In a laparoscopic nephrectomy, the surgeon makes several small incisions in the abdomen. A laparoscope (a camera) and specialized surgical tools are inserted. The abdomen is inflated with gas to create working space. The surgeon detaches the kidney and extracts it through a slightly enlarged incision in a special bag. Robotic-assisted surgery uses the same small incisions, but the surgeon controls robotic arms from a console, offering greater precision, which is particularly useful for partial nephrectomies. Minimally invasive methods generally result in less pain and faster recovery.

Surgical Risks
As a major operation, a nephrectomy carries significant risks, including adverse reactions to general anesthesia, heavy bleeding (which may require a blood transfusion), and the risk of blood clots forming in the legs or lungs.

General Complications
Common complications during the recovery period include:
– Pain and discomfort at the incision sites, which will require prescribed pain management.
– Fatigue and weakness, which can last for several weeks as the body heals.
– Digestive issues, such as temporary constipation or bloating, due to anesthesia and reduced mobility.
– A temporary decrease in overall kidney function, as the remaining kidney adjusts to taking on the full workload.

Rare but Serious Complications
Severe complications can occur and require immediate attention:
– Damage to surrounding organs, such as the spleen, liver, pancreas, or bowel.
– Post-operative pneumonia or other respiratory infections.
– Hernia at the site of the surgical incision.
– In partial nephrectomies, there is a risk of urine leaking from the remaining kidney tissue.
– Chronic kidney disease or kidney failure, particularly if the remaining kidney is not completely healthy.

Pre-operative Preparation
– Extensive Medical Evaluation: Comprehensive blood tests, kidney function tests, ECG, and detailed imaging (CT or MRI scans) are required to map the kidney’s anatomy and assess the health of the remaining kidney.
– Medication Adjustments: Blood thinners and certain other medications must be stopped well in advance.
– Fasting: Strict fasting (no food or drink) is required starting at midnight before the surgery.
– Bowel Preparation: A laxative or enema may be prescribed to clear the bowels before surgery.

Post-operative Care
Following a nephrectomy, patients are monitored closely in the hospital for 1 to 7 days, depending on the surgical approach. A urinary catheter will be in place for the first few days to monitor urine output. Intravenous (IV) fluids and pain medications will be administered. Patients are encouraged to perform deep breathing exercises and begin walking as soon as possible to prevent pneumonia and blood clots.

Wound Care
– Keep the incisions clean and dry. Follow the surgeon’s instructions regarding showering; baths are strictly prohibited until the wounds are fully healed.
– The incisions may be closed with staples, stitches, or surgical glue. Staples or non-dissolvable stitches will be removed at a follow-up appointment.
– Monitor the incision sites daily for signs of infection, such as increased redness, swelling, warmth, or drainage.

Diet
Patients will start with a liquid diet and gradually progress to solid foods as bowel function returns to normal. Long-term, patients with one kidney are often advised to follow a healthy, balanced diet to protect the remaining kidney, which may include monitoring protein intake and staying well-hydrated.

Post-discharge Notes
Full recovery can take 3 to 6 weeks for laparoscopic surgery and up to 12 weeks for open surgery.
– Strictly avoid heavy lifting (over 10 pounds) and strenuous activities for at least 6 weeks.
– Engage in light, daily walking to build stamina.
– Protect the remaining kidney by avoiding contact sports that could cause trauma to the abdomen or lower back.
– Attend all follow-up appointments to monitor kidney function and ensure proper healing. Seek emergency care if you experience a high fever, severe pain, shortness of breath, or a sudden decrease in urine output.
