Bladder cancer surgery patients are often left in a dilemma whether to choose a permanent stoma with an ileal conduit or restore normal urination with a neobladder after readical cystectomy.

The majority of the patients ultimately choose ileal conduit due to various myths associated with neobladder and circumstances: lack of neobladder expertise, complex and time-consuming surgery & higher complication rates.

However, access to the right uro oncologist working at high-volume neobladder surgery centres can drastically decrease neobladder complications.

In this blog, you'll explore the life-changing procedure of neobladder surgery, a reconstructive option for those undergoing radical cystectomy as part of their bladder cancer treatment.

Dr Rohan Patel, a leading Bladder Cancer Specialist in India at Apollo Hospital Ahmedabad and Ananta Urology Clinic, will guide you through what a neobladder is, how it compares to other urinary diversion options like the ileal conduit, and the benefits of choosing robotic surgery for this complex procedure.

You'll also gain insights into the recovery process, potential outcomes, and how a uro oncologist can make all the difference in your bladder cancer treatment journey.

What is Neobladder Procedure?

A neobladder is a reconstructive surgical procedure where a new bladder is created from a part of intestines (small or large) after bladder has been removed. It is primarily indicated for bladder cancer patients that have undergone bladder removal surgery. It is also indicated for other benign cases where bladder is removed or has become insufficient. Unlike other urinary diversion methods like ileal conduit that rely on permanent external devices, a neobladder is designed to function as closely as possible to a natural bladder, allowing the patient to urinate through the urethra in a normal manner.

The construction of a neobladder is a complex procedure. During surgery, the uro oncologist selects a portion of the small intestine—usually about 45-75 cm in length—and reshapes it into a spherical or pouch-like structure similar to a normal urinary bladder.

This neobladder is then connected to the ureters, which are the tubes that carry urine from the kidneys. The other end of the neobladder is attached to the urethra, the tube that allows urine to exit the body. The surgical connection between the neobladder and the urethra is a critical step, as it determines how well the new bladder will function.

How does Neobladder Function

The primary goal of a neobladder is to allow the patient to maintain as normal a urinary function as possible after the removal of the natural bladder. Unlike other forms of urinary diversion, such as an ileal conduit (where urine is diverted to an external bag), a neobladder is intended to store urine inside the body, much like a natural bladder.

Neobladder allows for controlled urination, giving patients a greater sense of normalcy and independence. Over time, patients learn to manage the neobladder, which involves retraining the muscles and nerves to control urination effectively.

Neobladder vs Ileal Conduit

When bladder removal is necessary, patients generally have two main options for urinary diversion: the neobladder or the ileal conduit.

An ileal conduit involves creating a stoma (an opening on the abdomen) and attaching an external bag where urine is collected. While effective, this method requires the patient to manage an external appliance for the rest of their life, which can be inconvenient and impact the patient’s self-image.

In contrast, a neobladder eliminates the need for an external bag, offering a more discreet and natural way of urinating. However, the choice between a neobladder and an ileal conduit depends on several factors, including the patient’s overall health, kidney function, and the ability to manage the post-operative care and retraining required for a neobladder.

Ideal Candidates for Neobladder Surgery :

Not everyone is a candidate for a neobladder. The best candidates are typically those who are in good overall health and have strong kidney function, as the surgery is complex and requires a robust recovery process. Additionally, patients need to be committed to the post-surgery retraining required to effectively use the neobladder. Factors such as age, prior health conditions, and the stage of bladder cancer are also considered when determining if a neobladder is the right option.

Choosing to undergo neobladder surgery is a significant decision, and it's crucial to have a thorough discussion with your uro oncologist to understand the benefits and challenges of this procedure. The ultimate goal is to provide a solution that best aligns with the patient’s lifestyle and medical needs, allowing them to regain as much normalcy and independence as possible after bladder cancer treatment.

Why Choose a Neobladder?

When facing the prospect of bladder removal, patients are often confronted with significant decisions about how their urinary function will be managed post-surgery. One of the most advanced and life-changing options available is the creation of a neobladder. But why choose a neobladder over other urinary diversion methods?

1. A More Natural Way of Urinating

One of the most compelling reasons to choose a neobladder is its ability to mimic the function of a natural bladder. Unlike other urinary diversion methods, such as an ileal conduit, which requires the use of an external bag to collect urine, a neobladder allows you to urinate through the urethra. This means you can maintain a normal urination process, giving you a greater sense of normalcy and control over your body after surgery. The ability to avoid an external appliance is a significant advantage for many patients, particularly when it comes to quality of life and self-image.

2. Improved Quality of Life

The psychological and social benefits of a neobladder cannot be overstated. Patients who undergo neobladder surgery often report a higher quality of life compared to those who use other forms of urinary diversion. The absence of an external bag eliminates concerns about leaks, odours, and the visibility of the appliance, which can be particularly important for those who lead active lives. Being able to urinate normally can also reduce the stigma and embarrassment that some patients feel after bladder removal, allowing them to feel more confident in public and social settings.

3. Elimination of External Appliances

Choosing a neobladder means you won’t need to manage an external urinary bag, as required with other diversion methods like an ileal conduit. This can be particularly appealing for those who are concerned about the maintenance and care of an external appliance. Without the need to change and clean an external bag, patients often find that their daily routine is simpler and more manageable. Additionally, the absence of an external appliance reduces the risk of skin irritation and infections, which can occur when using a stoma bag.

4. Long-Term Cost Savings

While the initial surgery to create a neobladder can be more complex and time-consuming than other urinary diversion methods, it may lead to long-term cost savings. Patients who use external urinary appliances often incur ongoing costs for supplies, such as bags, adhesives, and skin protectants. Over time, these expenses can add up. A neobladder eliminates these recurring costs, as it functions internally without the need for additional supplies, making it a more cost-effective option in the long run.

5. Active Lifestyle Compatibility

For individuals who lead an active lifestyle, a neobladder can be particularly beneficial. Whether you enjoy sports, travel, or outdoor activities, the freedom from an external bag allows you to participate fully without the worry of managing a stoma or the potential embarrassment of leaks. The neobladder’s ability to store urine internally and allow for normal urination means that patients can continue their favourite activities with fewer restrictions and greater confidence.

6. Robotic Surgery

The advent of robotic surgery has made the creation of a neobladder more precise and less invasive. In the next paragraph, we will highlight how robotic surgery has increased neobladder surgery uptake by patients and uro oncologists in India.

3. The role of the robotic surgeon

Robotic-assisted surgery is revolutionising the way complex procedures like neobladder construction are performed. This technique utilises Da Vinci robotic surgery technology to enhance the surgeon’s precision, control, and visualisation. During a robotic radical cystectomy, the surgeon controls robotic arms equipped with surgical instruments from a console, performing the surgery through small incisions.

The benefits of robotic surgery are particularly significant when it comes to neobladder construction. The increased precision allows for better preservation of surrounding tissues, reduced blood loss, and a lower risk of complications. Patients who undergo robotic-assisted surgery often experience shorter hospital stays, quicker recovery times, and improved overall outcomes. Choosing a highly skilled robotic surgeon, especially one experienced in bladder cancer treatment, is crucial for achieving the best results.

Key Benefits of Robotic Neobladder Surgery

1. Minimally invasive with faster recovery

2. Enhanced precision and lower risk of complications

3. Better functional outcomes and quality of life

4. Shorter hospital stay and faster return to normal activities

1. Minimally Invasive with Faster Recovery :

Robotic-assisted neobladder surgery is minimally invasive, meaning it requires smaller incisions than traditional open surgery.

Traditional open cystectomy with neobladder required a large incision (>15 cm) in the abdomen. This was associated with an increased risk of wound infection, wound dehiscence, delayed recovery, and delayed bowel movements.

Robotic cystectomy is done with 4-5 small incisions of less than 1 cm. This leads to less trauma to the body, less pain after the operation, and a quicker recovery time. Most patients can return home sooner and get back to their regular activities more quickly compared to those who undergo open surgery.

2. Enhanced Precision and Lower Risk of Complications :

The advanced robotic technology used in this procedure provides the surgeon with a high-definition, 3D view of the surgical site, along with highly precise instruments that can move in ways the human hand cannot.

There is scaling in the movement of robotic instruments which negates the transmission of tremors. Moreover, 10X magnification and 3-dimension picture of the robotic camera provide unparalleled vision and clarity to the uro oncologist surgeon while doing cystectomy. This allows for meticulous dissection and suturing of the bowel, reducing the risk of complications such as infection or damage to surrounding tissues.

3. Better Functional Outcomes and Quality of Life :

A key advantage of the robotic approach for neobladder is the improved functional outcomes it offers. Patients who undergo robotic neobladder surgery often experience better control over their new bladder, with a quicker return to normal urinary function. This leads to a better overall quality of life, as the neobladder allows for a more natural lifestyle without the need for external appliances.

4. Shorter Hospital Stay and Faster Return to Normal Activities :

The minimally invasive nature of robotic surgery not only reduces recovery time but also shortens the duration of hospital stays. Traditionally open cystectomy patients had hospital stay of 10-15 days. This was due to delayed bowel movements and pain at the incision site. With robotic radical cystectomy patients’ hospital stay is typically halved to 5-7 days. Patients typically spend fewer days in the hospital and can resume their normal activities, including work and exercise, much sooner than those who undergo traditional surgery.

Recovery and What to Expect After Neobladder Surgery

1. Immediate post-surgery care

2. Retraining the neobladder

3. Long-term outcomes and lifestyle adjustments

Recovery from neobladder surgery involves several stages, beginning with immediate post-operative care. Patients will typically stay in the hospital for a few days to a week, during which time they will be monitored for any complications. Pain management and wound care are important during this phase, and patients will gradually transition from IV fluids to a regular diet.

Once at home, the focus shifts to retraining the neobladder. Because the neobladder is made from intestinal tissue, it does not have the same nerve connections as a natural bladder. Patients will need to learn how to empty their new bladder regularly to prevent overfilling and stretching. This retraining process can take several months, and patients will need to work closely with their healthcare team to ensure success.

In the long term, most patients find that their neobladder provides them with a good quality of life. While some lifestyle adjustments are necessary, such as learning to manage nighttime urination, the ability to urinate normally during the day is a significant benefit. Regular follow-up appointments are crucial to monitor the health of the neobladder and to address any issues that may arise.
