Bilateral Nephrectomy: An Overview

Introduction:

Complete or partial removal of the kidney is known as a nephrectomy. When a kidney is donated or when the damage to the kidney prevents it from functioning properly, nephrectomy surgery is done. The types of kidney surgery are radial and partial nephrectomy. A simple or radical nephrectomy is the surgical removal of the kidney entirely. A partial nephrectomy is a surgical procedure in which only a portion of the injured kidney is removed. Partial or simple nephrectomies are no longer an option when both kidneys have sustained significant damage. During a bilateral nephrectomy, a surgeon removes both kidneys if one is no longer able to function independently. This is a big surgical procedure removing both kidneys. Usually, this is reserved for cases when no other therapy is effective. Following surgery, it necessitates renal replacement therapy or a kidney transplant from a donor.

What Is Bilateral Nephrectomy?

A bilateral nephrectomy involves removing both kidneys surgically. Sometimes, kidney transplantation is combined with a bilateral nephrectomy. While several disease states, such as vesicoureteral reflux (a disorder where urine travels from the bladder via one or both ureters, the renal calyx, and finally the kidneys), nephrolithiasis (a hard, small deposit that accumulates in the kidneys and is frequently uncomfortable to clear), glomerulonephritis (inflammation of the kidneys' small filters), hypertension (high blood pressure), and vasculitis (a collection of uncommon ailments, commonly referred to as angiitis, harm blood vessels by inducing swelling or inflammation), can be involved, autosomal dominant polycystic kidney disease (ADPKD) linked end-stage renal disease (ESRD) is the most prevalent etiology. It is carried out when the kidneys are too damaged to function properly, and neither kidney is strong enough to support the body's demands if the other kidney is removed.

When Is Bilateral Nephrectomy Needed?

When both kidneys are removed, additional renal assistance is required for survival, unlike a single nephrectomy, which would not require a kidney transplant or subsequent renal therapy. Because of this and the difficulty of the procedure, bilateral nephrectomies are only carried out as a last resort when no other course of treatment remains viable. Bilateral nephrectomy indications are as follows:

• Kidney cancer.

• End-stage renal disease (ESRD).

• Congenital defects (which are birth-related kidney dysfunctions).

• Hypertension (uncontrollable).

• Chronic infection that was resistant to treatment.

• Polycystic kidney disease (PKD).

What Are the Steps Involved in Bilateral Nephrectomy?

• A bilateral nephrectomy, sometimes referred to as traditional retroperitoneal surgery, is carried out by the surgeon either openly or laparoscopically.

• Patients get unconscious since the surgical team uses general anesthesia. A tube down the throat delivers oxygen and anesthetic to the lungs to keep someone asleep.

• During laparoscopic surgeries, the abdomen is made into small incisions. The term "keyhole surgery" refers to a procedure used in laparoscopy wherein the incisions are made only big enough for the surgeon to insert a lighted laparoscope and specialized surgical instruments.

• Carbon dioxide is inflated into the abdominal cavity to assist the surgeon in seeing better and having more area to work. Before the kidney surgery incision is closed, this innocuous gas is released. After a few days, the body spontaneously releases any residual carbon dioxide.

• Even though laparoscopy has advantages, including shorter recovery times between surgeries and better outcomes after that, the situation may call for open surgery to perform the bilateral nephrectomy.

• An extensive incision is made down the abdomen's midline during open surgery. Surgical instruments open the incision to create working space and a clear view of the abdominal cavity.

• Many patients undergoing bilateral nephrectomy also get a kidney from a donor. Although implanting a donor's kidney laparoscopically is possible, the process is difficult and involves a lot of work.

• Many surgeons choose open surgery for better surgical access and an unobstructed view of the entire surgical site.

How Long Does It Take to Have a Bilateral Nephrectomy?

How long kidney removal surgery takes for a bilateral nephrectomy varies depending on several factors, such as the conditions that caused the kidney damage, the general health, and the treatment plans one has for renal replacement. According to a 2020 research paper, which examined seven bilateral nephrectomies performed using an open technique, the procedure took an average of two hours and ten minutes, and it could take up to four hours to remove the kidneys.

What Preparations Need to Be Done Before Bilateral Nephrectomy?

Several preparations will be made in the days and weeks leading up to a bilateral nephrectomy. Various laboratory tests are performed by the physician, including:

• Ultrasound.

• Urinalysis.

• Ionogram (it calculates blood ion levels).

• Blood tests to evaluate kidney functions.

• Blood clot evaluation.

• Morphology (a microscope-based assessment of the cells' structure).

These tests inform patients about kidney health and the overall risk of bilateral nephrectomy surgery. One may require dialysis the day before the bilateral nephrectomy. This treatment removes waste materials from the blood and relieves some of the pressure during the kidney surgery.

The care team will also provide one with specific instructions the day before surgery about what and when to eat, how to wash the hands, and how to take any existing medications.

Making plans for home care or transportation in advance is advisable, as one may need to be more capable of doing so after the treatment. As is normally advised, dress comfortably and loosely on the day of the procedure.

What Should One Anticipate Following a Bilateral Nephrectomy?

What to expect after kidney removal and life after bilateral nephrectomy can be anticipated as follows:

• After bilateral nephrectomy surgery, patients recover in a warm, quiet room where the surgical team may closely monitor their vital signs and other renal health-related functions, such as blood pressure.

• After surgery, it is typical to have a urinary catheter to keep the bladder drained. This avoids discomfort and needless strain on the kidneys.

• Pain at the surgical site is typical, particularly in the first week following the procedure. One may get stabbing pain in the shoulder and chest after a laparoscopic procedure. This may be an unintended consequence of residual CO2 dispersing first.

• A hospital stay of several days is typical for most people. Before the patients return home, the care team wants to ensure their kidneys function normally and that their body tolerates new kidneys.

• Some people might require more dialysis treatments while recovering in the hospital, but dialysis has become a regular part of life.

• Dialysis filters blood in kidney transplant recipients until the recipient's replacement kidney starts to function. Bilateral nephrectomy recovery can take many weeks to complete.

How Much Time Does It Take to Recuperate From a Bilateral Nephrectomy?

The patient's general health determines the recovery time for kidney removal, any coexisting medical issues, and the level of support available once they leave the hospital. Although a person may recover to regular activities six weeks after bilateral nephrectomy surgery, it may take a year or more to recover from kidney removal fully.

What Are the Complications of Bilateral Nephrectomy?

A bilateral nephrectomy is a difficult and long surgery. Typical complications after kidney removal include the following:

• Blood clot.

• Infection and contaminations.

• Reactions from anesthesia.

• Postoperative pneumonia.

• Death.

Particularly, the following complications are linked to kidney removal:

• Harm to the tissues and organs nearby.

• Pneumothorax (trapped air in the chest cavity).

• Renal insufficiency (decreased blood flow to the kidneys due to renal artery disease may be the reason for their poor function).

• Incisional hernia (a kind of hernia brought on by a surgical wound that has not fully healed).

• Uremia (a disorder characterized by excessively elevated blood waste product levels, primarily urea and creatinine).

• Imbalance in electrolyte levels.

• Loss of blood leading to transfusion.

What Are the Survival Rates Post Bilateral Nephrectomy?

Several factors influence bilateral nephrectomy survival. Some that may impact life expectancy are kidney disease causes, renal replacement therapy outcomes, and general health. Over time, the bilateral nephrectomy technique has become increasingly safe. The overall postoperative death rate in 1978 was less than four percent for individuals under 50 and 11.1 percent for those over 50.

Conclusion:

A medical operation known as a bilateral nephrectomy involves kidney removal surgery of both sides. It is done when one kidney is removed because the other is so damaged that neither can function on its own. The doctor will talk to patients about renal replacement therapy or a kidney transplant if they are undergoing a bilateral nephrectomy. The mortality rate with bilateral nephrectomy is minimal. The effectiveness of renal medicines, underlying disease processes, and the present state of health all affect the total survival rate.
