Introduction:
Nephroureterectomy (NU) is the standard treatment of choice for invasive upper urinary tract cancer. The procedure has been widely used for over 100 years. However, new surgical techniques have paved the way for the evolution of nephroureterectomy. Nephroureterectomy can be done using different approaches, and the treatment procedure includes two steps, mainly radical nephrectomy and distal ureterectomy. Dentu and Albarran were the first to describe nephroureterectomy, wherein only a small portion of the ureter was removed. However, other researchers noticed tumor recurrences in distal portions of ureters. As a result, the scientists believed that resecting the entire ureter is paramount.
What Is Nephroureterectomy?
A nephroureterectomy is a surgery that aims to treat transitional cell cancer. The surgery simply removes the kidneys, ureters, renal pelvis, or bladder cuff. The renal pelvis is located at the center of the kidney. It works to collect urine and carries it into the tubes known as the ureters. The ureters are muscular tubes that carry urine from the kidneys to the bladder, a urine storage site. The junction between the ureter and the bladder is known as the bladder cuff. The doctor usually recommends nephroureterectomy for patients with urothelial cancer. It is a radical surgery wherein the doctor removes a tumor or other organs where the tumor has spread. For example, if cancer has spread to the colon, the doctor might remove the colon along with the kidneys and ureters. During an open nephroureterectomy, the doctor makes two large incisions in the abdomen to remove the rib. The first incision is usually 8 to 12 inches long. Large and invasive tumors might require an open surgical approach. However, most procedures can be done through robot-assisted techniques. Hence, technology has made procedures convenient and easily accessible.
Why Is a Nephroureterectomy Done?
A nephroureterectomy is a standard treatment protocol for patients with transitional cell cancer of the ureters or renal pelvis, especially if the tumor is aggressive. Hence, the patient must know everything about the treatment options available for cancer. Laparoscopic radical nephroureterectomy is helpful for patients with transitional cell cancer in the urinary tract or transitional membrane. The urine is expelled from the body through the urinary system, which includes the kidneys, urinary bladder, ureter, and urethra. Transitional epithelium is a membrane that lines the ureters, kidneys, and urinary bladder.
What Are the Types of Nephroureterectomy Surgery?
Even though nephroureterectomy is a significant surgery, the process can vary based on the situation.
The three primary categories are as follows:
Nephroureterectomy by Radical Means:
A cuff of healthy bladder tissue surrounding the ureter's entrance is removed together with the entire damaged kidney and ureter in this most common type of nephroureterectomy.
It is the recommended strategy for:
1. Aggressive Transitional Cell Carcinoma: When the carcinoma is big, has spread outside of the ureter's inner lining, or affects lymph nodes in the area.
2. High-Grade Transitional Cell Carcinoma: A more aggressive form of cancer with a greater propensity to spread is referred to as high-grade TCC.
Extraordinary situations involving radical nephroureterectomy:
1. Lymphadenectomy: The surgeon may also conduct a lymphadenectomy in conjunction with a radical nephroureterectomy. Some lymph nodes close to the kidney are removed to check for the spread of malignancy. The degree of lymph node excision may change depending on the particular circumstance.
2. Bladder Cuff Resection: The quantity of bladder tissue and ureter removed may vary. A larger margin of healthy bladder tissue may occasionally be excised to guarantee total cancer removal.
Easy removal of the kidneys:
The entire damaged kidney and ureter are removed during this treatment, but the bladder cuff is left intact. It could be taken into account for:
1. TCC in Its Early Stages: When the cancer is limited to the ureter's inner lining and has not spread outside a tiny area.
2. Low-Grade TCC: Low-grade TCC is a less aggressive form of cancer with a decreased propensity to spread.
3. Benign Tumors: To remove a non-cancerous tumor in the kidney or ureter, a straightforward nephroureterectomy may be necessary in some circumstances.
Nephroureterectomy for Prevention:
This kind of nephroureterectomy is highly uncommon and is done as a prophylactic. If there is a very high chance of developing TCC in the future, a healthy kidney and ureter are removed. This could be taken into account in circumstances such as:
1. Severe Familial TCC: If genetic testing indicates a high predisposition and you have a strong family history of TCC, with several near relatives afflicted.
2. Chronic TCC: In rare instances, a person may experience repeated TCC recurrences in the same kidney despite prior treatment.
What Happens Before a Nephroureterectomy?
The patient must consult the doctor before undergoing a nephroureterectomy. The doctor examines the patient’s general health and checks the vitals, including blood pressure, pulse rate, and temperature. The patient must inform the doctor about all the prescription or over-the-counter medications, including herbal supplements. This is because Aspirin, anti-inflammatory drugs, and other supplements can increase the risk of bleeding. Hence, the patient must communicate with the doctor before discontinuing any medications. The patient must inform the doctor about the allergies, including allergies to skin cleaners like iodine, latex, food items, and isopropyl alcohol. The doctor might provide particularly specific instructions on drinking or eating. Hence, the patient must take a liquid diet 24 hours before the surgery. Avoid eating anything the night before the surgery.
How Do the Doctors Perform Nephroureterectomy?
Nephroureterectomy is a surgical procedure that typically includes a team of urologists, nurses, and anesthesiologists. First, the patient is given general anesthesia to make him fall asleep and to avoid movements during the procedure. Once the patient falls asleep, the urologist uses a sharp, sterile knife or a scalpel to make small incisions in the abdomen. Next, a laparoscope is inserted through the incisions to examine the affected organs. Finally, the urologist uses sutures to close the incisions. Sometimes, the doctor might place a silicone or drainage tube at the incision sites to drain the blood or fluid. The entire procedure is completed in two to four hours.
Step-by-Step Procedure of Nephroureterectomy
The following are the step-by-step procedures for nephroureterectomy:
-
Before surgery, you will also receive special dietary and drinking instructions from your healthcare provider. For 24 hours before surgery, consume only clear liquids. You should avoid eating anything after midnight on the night before your procedure. Medication should be taken with a little sip of water if required.
-
You will be sedated by your anesthesiologist using general anesthesia.
-
Your urologist will gently make multiple tiny incisions in your abdomen while you are unconscious using a sharp, sterilized knife (scalpel). A powerful laparoscope will then be inserted via the incisions to inspect the impacted areas.
-
Through one of your incisions, your urologist will remove your afflicted organs using small, specialized surgical tools.
-
Ultimately, your urologist will sew your wounds shut. They might insert drainage tubes and small silicone tubes into the areas where you were cut. Fluid or blood is drained through the drainage tubes, which are then sewn in place.
What Happens After a Nephroureterectomy?
The patient will be taken to a recovery room after the procedure. Next, the stitches are covered with bandages. The patient might take some time to overcome the effect of anesthesia. Once the patient is fully awake, the doctor might administer painkillers to allow the pain to subside completely. General anesthesia can often cause nausea; hence, the doctor might provide medications to overcome nausea. The patient is asked to maintain a liquid diet for one or two days after the surgery. This is because a liquid diet helps the body recover. The patient can start taking solid foods a few weeks after surgery. The doctor might encourage the patient to walk a day after surgery because walking enhances nephroureterectomy recovery. In addition, it reduces the risk of blood clot formation and pneumonia (respiratory infection). Once the doctor is assured, the patient will be allowed to go home.
What Are Some of the Risks and Complications of Nephroureterectomy?
All surgical procedures are associated with certain risks or complications. Some of the risks of nephroureterectomy are listed below:
-
Untoward reactions at the site of infusion.
-
Delayed wound healing.
-
Need for blood transfusion.
-
Infections.
-
Formation of hematoma (localized collection of blood).
-
The buildup of fluids at the surgical site, or seroma.
How Long Would a Patient Take To Recover After a Nephroureterectomy?
The patient must relax for about six weeks after the procedure. In addition, one must avoid driving for about two weeks after the procedure. The patient must avoid strenuous activities or exercises, including running or lifting heavy objects. This is because strenuous physical activities can cause undue strain on the stitches, resulting in a hernia (tissue pushes through a weak area) or injury. Every individual has a unique body, so the recovery time might vary. Hence, the patient must be aware of his body and its limitations.
When Should the Patient Consult the Doctor After the Procedure?
The patient must schedule follow-ups and consultations with the doctor to evaluate incisions or stitches. The stitches might be removed after two or three weeks if they are not dissolvable. In addition, the doctor might remove the drainage tube and the stitches. The doctor also performs several tests to ensure the transitional cell cancer has subsided.
The patient must consult the doctor immediately under the following circumstances:
-
Profuse bleeding at the site of the incision.
-
Drainage of discharge from the stitches.
-
High fever.
-
Infections.
-
Foul odor.
-
Presence of pain.
Conclusion:
A nephroureterectomy is one of the most effective treatment methods for transitional cell cancer. It can be done using the open or robot-assisted laparoscopic approach. Though the procedure appears complicated, the patient must consult the doctor to learn more about the risks and benefits.
