Cystectomy is a surgical procedure that involves the partial or complete removal of the bladder. This surgery can be performed using different techniques depending on your health condition and the stage of the disease.
Partial cystectomy, on the other hand, is an organ-preserving surgical method where the tumor-affected area of the bladder is removed along with healthy surgical margins, without removing the entire bladder. Thus, bladder functions can be preserved in suitable patients while ensuring oncological control. However, keep in mind that partial cystectomy is not suitable for every bladder tumor patient.
Robotic partial cystectomy is a more modern approach compared to classical cystectomy surgery. Robotic surgery is performed similarly to laparoscopic methods, but the surgeon performs the operation with the assistance of a robotic system. In this article, you will learn clearly what robotic partial cystectomy is, in which situations it is preferred, and the advantages it offers you.
What is Robotic Partial Cystectomy?
Modern medical technology offers less invasive options for the treatment of bladder cancer. Partial cystectomy and robotic surgery are significant developments in this area.
What is Partial Cystectomy?
Partial cystectomy (PC) is a procedure used in the treatment of bladder cancer, where only the tumor-affected part of the bladder is removed. In this surgical intervention, the entire bladder is not removed; only the diseased area is excised while preserving the healthy tissue of the bladder. The primary aim of partial cystectomy is to completely eliminate cancerous tissue while preserving urinary function as much as possible.
This approach is generally preferred in cases where the cancer is localized to a specific area of the bladder and has not spread to other regions. It is particularly suitable for the treatment of small and localized tumors. After surgery, your urinary functions can be largely preserved, but this process may vary depending on the size and location of the tumor.
Partial cystectomy is an organ-preserving surgical method for bladder tumors, aiming to provide oncological control while preserving bladder functions in suitable patients. However, it is important to note that this procedure can only be applied in selected cases.
The Role of Robotic Surgery in This Process
Robotic partial cystectomy retains all the features of classical partial cystectomy but offers a more precise and less invasive approach. In the robotic surgical system, the surgeon directs robotic arms through a console and performs the surgery using these arms.
In robotic surgery, 4-6 small incisions are made in your abdomen. One of these incisions is used for the camera, while the others are used for surgical instruments. The robotic system provides the surgeon with three-dimensional, high-resolution images and advanced dexterity. As a result:
- The surgeon can see the surgical area in much more detail.
- The risk of damaging healthy tissues is reduced.
- A more precise and controlled surgical intervention can be performed.
Although robotic surgery is similar to laparoscopic methods, the greater range of motion of the robotic arms allows the surgeon to work with much more precision. Additionally, robotic cystectomy reduces bleeding, accelerates the recovery process, and minimizes postoperative pain.
In conclusion, robotic partial cystectomy is an advanced surgical option that allows you to maintain your quality of life by preserving bladder functions when applied to the right patient and the right indication.
In Which Situations is Robotic Partial Cystectomy Applied?
Patient selection for robotic partial cystectomy is the most critical determinant of treatment success. Only 5-10% of bladder cancer cases are considered suitable for partial cystectomy. Therefore, the correct patient and tumor selection is of great importance to achieve successful outcomes.
Preferred in Solitary and Localized Tumors
Robotic partial cystectomy is primarily preferred in solitary bladder tumors. This approach is effective in cases where the tumor is located in a specific and limited area of the bladder. Especially if the cancer has not spread to many places in the bladder or other regions, partial cystectomy may be a suitable option.
Additionally, tumors located in the dome or lateral wall of the bladder are also ideal candidates for robotic partial cystectomy. Removing tumors in these areas does not significantly affect bladder functions.
Lesions Away from the Trigone and Ureteral Orifices
The location of the tumor is a determining factor in the decision for robotic partial cystectomy. Ideally, the tumor should be away from the trigone (the triangular area at the base of the bladder), bladder neck, and ureteral orifices. This is particularly important because:
- These areas are essential for the critical functions of the bladder.
- Surgery performed near the ureteral orifices can affect urine flow.
- The tumor must be in a safe and removable position.
However, patients without carcinoma in situ (CIS) and those without multifocal tumors are also suitable candidates for robotic partial cystectomy.
Patients Not Suitable for Radical Cystectomy
In some patients, radical cystectomy (complete removal of the bladder) may carry a high risk. In these cases, robotic partial cystectomy can be an alternative treatment method. This patient group typically includes:
- Those whose general health is suitable for surgery but carry risks for extensive surgery.
- Those who want to preserve bladder function.
- Those who want to avoid radical cystectomy to maintain urinary function and quality of life.
Robotic partial cystectomy can also be applied in selected T2 stage muscle-invasive but localized tumors. However, it should be noted that the potential for complete tumor removal must be high.
Uracheal Origin Bladder Adenocarcinomas
Experts consider uracheal origin bladder adenocarcinomas as the most ideal indication for robotic partial cystectomy. These types of tumors are located in the dome of the bladder and are generally easier to surgically remove.
It is important to note that robotic partial cystectomy must always be performed in conjunction with pelvic lymph node dissection. This is a critical step to detect possible cancer spread and ensure oncological control.
How is Robotic Partial Cystectomy Performed?
Robotic partial cystectomy is a minimally invasive surgical technique used in bladder cancer. This procedure is performed through high-tech robotic systems and involves smaller incisions compared to traditional open surgery.
Preoperative Preparation Process
A comprehensive preparation process is required before robotic partial cystectomy. First, imaging methods such as CT, MRI, or cystoscopy are used to evaluate the size, location, and spread of the tumor. These examinations show the condition of the tumor within the bladder while also assessing the lymph nodes, liver, lungs, and bones.
Preparations for general anesthesia begin 10-15 days before the operation. In this context:
- Complete urinalysis.
- Complete blood count.
- EKG (electrocardiogram).
- Blood sugar, liver, and kidney function tests.
- Tests such as chest X-ray are performed.
At least 7-8 days before the surgery, anticoagulant medications such as Aspirin and Coumadin should be discontinued. Additionally, it is also important for the patient to be admitted to the hospital one day before the procedure to clean the intestines and start prophylactic antibiotic treatment.
Use of the Robotic System
In robotic surgical technique, instead of a wide 15 cm incision in open surgery, 4-6 small incisions are made in the abdominal area. One of these incisions is used for the camera, while the others are used for surgical instruments. The surgeon controls the robotic arms while sitting at a console.
Robotic surgical systems like Da Vinci provide three-dimensional, high-resolution images with 12x magnification. The robotic arms mimic the surgeon’s hand movements exactly, allowing for more precise maneuvers. This minimizes damage to surrounding tissues and preserves the nerve-vascular structures that provide sexual function, especially in men.
Pelvic Lymph Node Dissection
Pelvic lymph node dissection is an important part of robotic partial cystectomy. By performing lymph node dissection, accurate staging is achieved and possible micrometastases are prevented. It also identifies patients who may need adjuvant chemotherapy.
This procedure is deemed necessary to prevent nodal disease and prolong survival. The precision of the robotic system allows for more complete removal of lymph nodes, thereby reducing the risk of cancer spread.
Surgery Duration and Technical Details
The robotic partial cystectomy procedure typically lasts 5-7 hours. However, the duration of the surgery may vary depending on the stage of the tumor, the patient’s overall health, and the extent of the surgery. Abdominal adhesions and the extent of tumor spread are also factors that can affect the duration of the surgery.
Technically, during the procedure, the bladder is mobilized, and a cystotomy is performed from a point distant from the tumor. The bladder wall is excised completely, leaving a 2 cm safety margin from the tumor, along with healthy tissue, adjacent perivesical fat, and peritoneum. A frozen examination is performed at the surgical margin, and after hemostasis, the bladder is closed with absorbable sutures.
At the end of the procedure, a Foley catheter is placed in the bladder, and a drain is placed in the Retzius space. One of the most important advantages of robotic surgery is that there is very little bleeding during the procedure, postoperative pain is minimal, and the patient’s recovery process is faster.
What are the Advantages and Disadvantages?
Robotic partial cystectomy provides many advantages in the treatment of bladder cancer, while also bringing some significant limitations. Understanding the positive and negative aspects of this modern surgical approach will help you make more informed decisions during the treatment process.
Preservation of Natural Urination Function
One of the most important advantages of robotic partial cystectomy is its ability to preserve your natural urination function. While radical cystectomy requires urinary diversion (ileal conduit, neobladder, etc.), in partial cystectomy, the functional part of your bladder is preserved. Thus, your bodily integrity is maintained, and the necessity of carrying a bag is eliminated.
Preservation of your bladder functions significantly affects your quality of life. Especially the preservation of the bladder can positively influence your self-confidence and sexual adaptation. Studies have shown that patients with preserved bladders feel more attractive and return to their sexual lives more easily.
Additionally, thanks to the precision provided by the robotic system, the nerves surrounding the bladder can be better preserved. This contributes to the faster recovery of urinary control and sexual functions after surgery.
Shorter Recovery Time
Another significant advantage of robotic partial cystectomy is the faster recovery process. Since robotic surgery is performed with a few small incisions, postoperative pain is much less, and wound healing accelerates.
Patients are generally discharged within 1-2 days after robotic cystectomy, while this duration is longer in open surgery. Due to the minimally invasive approach, complications such as infection, bleeding, and wound opening are much rarer compared to open surgery.
Blood loss during the procedure is minimal. This both increases safety and accelerates the recovery process. Thanks to the three-dimensional, 12x magnified images and precise maneuvers provided by robotic surgery, minimal damage is done to surrounding tissues.
The early return of bowel functions and the earlier initiation of nutrition also allow for a rapid increase in the patient’s quality of life.
Local Recurrence Risk and Need for Close Monitoring
The most significant disadvantage of robotic partial cystectomy is that the risk of local recurrence is higher compared to radical cystectomy. The remaining mucosa of the bladder remains at risk for tumor development, and recurrence rates range from 12-26%.
Recurrences after partial cystectomy usually occur within the first 2 years after surgery. Therefore, close and lifelong cystoscopic monitoring is essential. Regular imaging, cystoscopy, and cytology monitoring during postoperative follow-ups are critically important.
Reduced functional bladder capacity after partial cystectomy can emerge as a challenging problem. In some patients (12%), serious irritative urination symptoms and the resulting bladder dysfunction (5%) have been reported, necessitating urinary diversion.
It should be noted that incorrect patient selection can lead to oncological failure, and some patients may require delayed radical cystectomy in the future. Therefore, the characteristics of the tumor and the patient’s condition should be carefully evaluated.
Postoperative Process and Quality of Life
The recovery process after robotic partial cystectomy is as important as a successful surgery. During this period, proper care and monitoring will accelerate your physical recovery and maintain your quality of life.
Length of Hospital Stay
Your length of stay in the hospital after robotic partial cystectomy is significantly shorter compared to classical open surgery. Generally, it is sufficient to stay in the hospital for 3-5 days after robotic surgery. During this time, your pain control is managed, and your nutrition and fluid intake are gradually initiated. The significantly shorter length of stay compared to open surgery is one of the important advantages of robotic surgery.
Reconstruction of Urinary Tract
Since a part of your bladder is preserved after partial cystectomy, urinary diversion is generally not required. However, in cases requiring radical cystectomy, reconstruction of your urinary tract may be necessary. In this case, two main methods are used: ileal conduit (urostomy) or orthotopic neobladder (artificial bladder). In the ileal conduit method, a stoma is created in the abdominal wall for urine storage. The orthotopic neobladder allows you to urinate normally by placing a bladder reconstructed from the intestine.
Use of Artificial Bladder (Neobladder)
An artificial bladder is a pouch created from a portion of your intestines when your bladder needs to be removed. Thus, urine accumulates and is stored within this pouch. The surgery for an artificial bladder performed with robotic surgery is more advantageous than that performed with open methods. The most important difference is that no large incision is made in your body; the surgery is performed through 4-5 small openings in the anterior abdominal wall. The artificial bladder has no lifespan; you can use it for as long as you live.
Diet and Exercise Recommendations
In the first weeks after surgery, you should pay attention to your nutrition. You should start with liquid foods in the first days and gradually transition to normal nutrition. Adequate water intake is very important for the healthy functioning of your kidneys and urinary tract. A diet rich in fiber and protein, which does not strain your intestines, is recommended. You should avoid heavy physical activity and exercises for 4-6 weeks after surgery. Regular walking, pelvic floor exercises, and light sports strengthen both your physical and mental balance.
Psychological Support and Patient Education
Receiving psychological support after bladder surgery is very important. The removal of your bladder and the creation of an artificial bladder can lead to emotional responses such as changes in body perception, anxiety, shame, or loss of self-esteem. However, this situation is temporary; with the right support, information, and environmental adaptation, you can lead an active and fulfilling life again. Methods such as psychotherapy, patient support groups, family education, and meditation can strengthen your emotional adaptation. A few months after the surgery, you can return to your social and work life. Your quality of life will increase rapidly with regular check-ups and following your doctor’s recommendations.
In Summary, Robotic Partial Cystectomy
Robotic partial cystectomy is presented as an option in the treatment of bladder cancer. This method allows for the complete removal of cancerous tissue while preserving bladder functions in suitable patients. It is particularly preferred in solitary and localized tumors, and lesions away from the trigone and ureteral orifices.
Robotic cystectomy offers many advantages over traditional open surgery. Smaller incisions, less pain, faster recovery, and shorter hospital stays are among these advantages. Additionally, thanks to three-dimensional, high-resolution images, the surgeon can perform more precise maneuvers.
However, like every treatment method, robotic partial cystectomy has some limitations. Accordingly, the risk of local recurrence is higher, and lifelong regular follow-up is required. Therefore, correct patient selection is critical to achieve successful results.
Your quality of life is largely preserved after robotic partial cystectomy. The continuation of your natural urination function positively affects your self-confidence and social life. Nevertheless, you must adhere to your doctor’s recommendations and not skip regular check-ups during the postoperative process.
In conclusion, robotic partial cystectomy is a valuable surgical option offered by modern medicine that prioritizes patient comfort and quality of life. However, it should be noted that it cannot be applied to every patient and requires close monitoring. If you have been diagnosed with bladder cancer, discussing this treatment option with your doctor will be greatly beneficial.
