Robotic Urology

Robotic urology is the most advanced minimally invasive (closed) surgical method used in the treatment of prostate, kidney, and bladder diseases, in which the surgeon’s finger movements are transferred to robotic arms with millimetric precision under high-resolution three-dimensional imaging. This technology, performed with the Da Vinci surgical system, offers a modern standard that accelerates the recovery process and improves functional success by minimizing tissue damage, particularly in the treatment of prostate cancer and kidney tumors. Unlike traditional approaches, these operations, performed through very small incisions made in the body, aim to provide a high level of safety and operational comfort for patients thanks to high optical clarity in the surgical field and tremor-filtering software.

What Is Robotic Urology and Which Technological Foundations Is It Based On?

When you think of robotic surgery, you may imagine a machine that makes its own decisions, is programmed, and performs surgery by itself. However, this is a very common misconception. These systems never replace the surgeon, cannot move on their own, and cannot cut or shape tissue by themselves. In fact, this technology is an extremely advanced transfer tool that completely conveys the commands from the surgeon’s fingertips into the depths of the patient’s body. Whatever the surgeon does, the robotic arms do the same; the main difference is that these movements can be performed with greater precision, without tremor, and on a millimetric scale.

There are three main components at the heart of this advanced system. The main control center, or console, where the surgeon sits in a sterile area just outside the operating table, the body section positioned over the patient that contains the arms and performs the procedure, and a technological tower through which the entire operation is instantly projected onto large screens. The surgeon sits at the console as if in the cockpit of an aircraft. The surgeon places the eyes into a special viewer and positions the fingers on sensor-equipped control handles. Moving the hands to the right, left, upward, or downward enables those tiny instruments inside to move in the same direction.

The system’s hardware components are as follows:

• Surgeon control console
• Patient-side robotic unit
• High-resolution imaging tower
• Millimetric surgical instruments (EndoWrist technology)

The purpose behind the development of this system was to surpass the limitations of traditional open operations and even older types of minimally invasive operations, namely laparoscopy. Being able to work comfortably in areas too narrow for the human hand to enter and on tissues too small for the human eye to see was one of medicine’s greatest dreams, and this technology has made that dream a reality.

What Mechanical Advantages Does Robotic Urology Offer Patients and Surgeons?

The human body is a magnificent design, but the human hand has certain natural anatomical limitations. Think of your own wrist; you cannot bend your hand beyond a certain angle or rotate it completely around itself. This limitation of movement creates a major challenge, especially when working in a very deep, dark, and narrow area of the body such as the pelvis. This is where technology comes into play. The tips of those thin surgical instruments placed inside the patient’s body were designed by taking inspiration from the human wrist but going far beyond it. These instruments can rotate almost two full turns around themselves, with a range of motion of 540 degrees, and bend in seven different directions. In this way, sutures can be placed very comfortably even at the narrowest angles, and tissues can be separated from one another easily.

Another remarkable feature is motion scaling. During a major operation, precision as small as one tenth of a millimeter may sometimes be required. When the surgeon moves the hand five centimeters outside at the console, the system filters this movement and moves the tip of the instrument inside only one centimeter or a few millimeters. In other words, a large and coarse external hand movement turns into an extremely delicate and microscopic touch inside the patient’s body.

In addition, every human hand has a physiological tremor that we do not notice in daily life but that becomes visible under a microscope. This tremor may create a risk when suturing a very fine blood vessel. The system largely filters and reduces this tremor. It provides high stability while the tips of the instruments are operating.

Why Is Imaging Technology So Critical in Robotic Urology Applications?

You cannot treat something you cannot see. This is the most fundamental golden rule of surgery. In older-generation minimally invasive operations, physicians viewed the image from a camera sent into the abdomen on a flat, two-dimensional screen just like the televisions in our homes. Working while looking at a two-dimensional screen is like trying to thread a needle with one eye closed; your depth perception disappears. Your brain has to estimate how far away or how close something is.

However, imaging in these new-generation systems is completely three-dimensional. When the surgeon places the eyes into the console, it feels as though the surgeon has entered the patient’s body. Depth perception is highly pronounced. Moreover, these high-resolution cameras can magnify the operating area up to twenty times more than the naked eye can see.

Capillaries, very fine nerve networks, muscle fibers, and the delicate line where the tumor ends and healthy tissue begins, which are normally almost impossible to see with the naked eye, are displayed before the surgeon at the size of a giant screen and with crystal clarity. Thanks to this clarity, while diseased tissue is largely removed from the body, the likelihood of preserving vital tissues that enable the person to maintain normal functions increases significantly.

Why Is Robotic Urology Considered the Gold Standard in Prostate Cancer?

Prostate cancer, one of the most common health problems in men, is one of the most anatomically challenging diseases to operate on. The prostate gland is a walnut-sized organ hidden at the very bottom of the pelvis, almost at the lowest point of a narrow funnel. In open operations, reaching this deep area, providing adequate illumination, and using the hands comfortably in that very narrow space are extremely difficult. While treating cancer in this region, surgeons have three very clear main objectives they aim to achieve.

The primary objectives of prostate cancer surgery are as follows:

• Complete removal of cancerous tissue from the body (Oncological control)
• Preservation of the ability to hold urine (Continence)
• Maintenance of sexual functions (Potency)

Achieving all three of these goals at the same time is only possible with very clear vision and a high range of motion. Ensuring that cancer is not left behind in the body is the highest priority. Thanks to enormous three-dimensional magnification, the boundaries of the tumor can be identified more clearly, and the aim is to remove the prostate gland from the surrounding tissues while leaving a safe margin. In this way, the likelihood of cancer cells remaining behind is reduced very significantly, and the possibility that the patient may need additional oncological treatments such as radiation therapy or hormone therapy in the future is minimized. After cancer control is achieved, the other two important stages that will determine the patient’s quality of life are addressed.

How Does Robotic Urology Minimize the Problem of Urinary Incontinence?

The prostate is located directly beneath the urinary bladder, and the channel through which urine is expelled passes through the exact center of this gland. When the cancerous prostate gland is removed from the body, a space equal to the area previously occupied by the prostate forms between the urinary bladder and the urinary channel. One of the most delicate parts of the operation is reconstructing this pipeline securely by suturing the opening of the urinary bladder back to the urinary channel (Anastomosis).

If this suturing procedure is not performed properly, leakage may occur or the sphincter muscle responsible for urinary continence may be damaged. This may cause the patient to experience urinary incontinence for life and require constant pad use. Placing this suture in that deep and narrow area using the thick instruments of open surgery and the human hand truly requires great skill. However, thanks to advanced technological arms, these two tissues can be joined even in that narrow area using very fine sutures and in a way that minimizes the risk of leakage.

While the sutures are being placed, the tissues are not stretched or damaged, and the urinary continence muscle is clearly visualized and preserved thanks to extraordinary optical magnification. Because of this strong anatomical reconstruction, patients are freed from the catheter placed after surgery within a much shorter time. After the catheter is removed, the speed at which the ability to hold urine normally returns is much earlier and more successful compared with traditional methods. This prevents the patient from withdrawing from social life and accelerates psychological recovery to an incredible degree.

How Can Sexual Functions Be Preserved Through Robotic Urology?

The second greatest concern occupying the minds of patients who will undergo prostate cancer surgery is the permanent erectile problem that may occur after surgery. The vascular and nerve networks responsible for sexual function in men and extending to the penis, known as the neurovascular bundle, adhere to the right and left sides of the prostate like a very fine spider web, surrounding it like a shell and extending downward.

In traditional methods, these hair-thin nerve fibers may be unintentionally cut or damaged while the prostate is being removed, mostly due to bleeding and inadequate visibility. Unfortunately, when the nerves are severed, sexual functions are irreversibly lost. However, with today’s technology, cameras providing twentyfold magnification show these extremely fine nerve networks like thick ropes.

If the cancerous tumor has not extended beyond the outer membrane of the prostate, a very special technique called “nerve-sparing” is applied. With the help of extremely fine robotic scissors, these nerve fibers over the prostate are separated very slowly, patiently, and gently, as though peeling the membrane from a thin-skinned fruit. The nerves are stripped away from the prostate and left intact in their beds, while only the cancerous prostate gland is removed. With correct patient selection and careful application, this delicate separation procedure can preserve men’s sexual quality of life at very high rates close to the preoperative level.

How Does Robotic Urology Save the Organ in Kidney Cancers?

The kidneys are magnificent factories that clean and filter the blood in our body and are indispensable for the continuation of life. In earlier years, when a mass or cancer was detected in the kidney, the entire kidney was generally removed from the body regardless of the size of the tumor. However, with advances in medical science, it was understood that preserving healthy kidney tissue in the body is vitally important to prevent the patient from developing kidney failure in later years and to protect cardiovascular health.

Today, if the tumor has not reached an enormous size, the basic philosophy is to remove only the cancerous part rather than the entire kidney and leave the healthy kidney in the patient. This is called organ-sparing surgery (Partial nephrectomy). However, the kidney is highly vascularized and resembles a sponge filled with blood. When a piece is cut and removed from it, severe bleeding begins. To stop this bleeding, the main vessels supplying the kidney are temporarily compressed with a special clamp to stop the blood flow.

At this point, a major race against time begins. Kidney tissue cannot withstand being deprived of blood for a long time. The surgeon must remove the tumor very quickly, rapidly close the remaining open kidney wound with sutures, and release the clamp on the vessel to restore blood flow to the kidney. The speed of the technology, the flexibility of the instruments, and the ability to suture rapidly minimize this bloodless period. The tumor is removed while trying to keep the effect on healthy kidney tissue to a minimum, and the function of the organ is largely preserved.

Methods frequently applied in kidney operations are as follows:

• Removal of only the tumor (Partial nephrectomy)
• Removal of the entire kidney (Radical nephrectomy)
• Intervention on the adrenal gland (Adrenalectomy)

This technology is used even when the tumor is very large and complete removal of the kidney is mandatory. Ligation of major vessels in a much safer manner and removal of the kidney using a minimally invasive method without damaging other surrounding organs mean that the patient is spared from a large flank incision.

What Solutions Does Robotic Urology Provide for Kidney Channel Obstructions?

This technology is used extensively not only in cancer diseases but also in certain congenital or acquired structural disorders. Urine produced in the kidney is carried to the urinary bladder through a very thin, long tube called the ureter. Sometimes an obstruction or narrowing occurs exactly at the point where this tube exits the kidney (UPJ obstruction). Because of this narrowing, urine cannot flow downward, accumulates inside the kidney, and causes the organ to swell and gradually deteriorate and lose its function.

To solve this problem, the abnormal narrowed section must be cut out and the remaining healthy channel must be sutured back to the kidney. The channel in question is as thin as a drinking straw, and suturing this tube together without leakage in that narrow region of the kidney using large hands with limited mobility is a true art of tailoring. Thanks to technological software that filters and scales down fine movements, this tiny channel is reconnected smoothly to the kidney. With the sutures placed precisely, the aim is to restore normal urine flow and enable the kidney to recover. Since patients are not exposed to the muscle incisions of open operations, their recovery is remarkably comfortable.

How Does Robotic Urology Manage the Process in Bladder Cancer?

Bladder cancers, especially when the disease has progressed into the muscle layer, require some of the largest, most comprehensive, and physically demanding operations in the entire field of urology. In such a situation, complete removal of the urinary bladder from the body (Radical cystectomy) is mandatory. However, the matter does not end with removing the urinary bladder; an entirely new drainage system, a new structure that will carry urine descending from the kidneys outside the body, must be built.

This reconstruction process is generally performed by taking a segment from the patient’s own small intestine. When this operation is performed using the open method, opening the abdomen from one end to the other, exposing the intestines to outside air for hours, and experiencing major blood loss are unavoidable. This situation significantly delays postoperative recovery, especially in elderly individuals or those with additional diseases.

However, in new-generation minimally invasive systems, the bladder is separated from its location without opening the abdomen, entering only through small openings. With the wide field of view provided by the camera system, all lymph nodes in the abdomen to which the cancer may spread are meticulously removed. Because blood vessels are sealed and cut using special heating instruments, the amount of bleeding is significantly reduced. After the diseased organs are removed, the stage of reconstructing the urinary tract begins.

The options used in urinary tract reconstruction are as follows:

• A new artificial bladder from the intestine (Orthotopic neobladder)
• Directing urine to a bag (Ileal conduit)
• Connecting the urinary tract to the large intestine

All of these reconstruction procedures can be performed safely within that small working area inside the abdomen thanks to the maneuverability of the technological arms. Because the intestines are not brought outside the abdomen and exposed to air, postoperative intestinal sluggishness is seen much less frequently, patients begin eating sooner, and they regain normal digestive functions much more quickly.

What Is the Recovery Journey of Patients Like After Robotic Urology?

Just as making the decision to undergo surgery is difficult for a patient, the hospitalization and recovery period afterward is equally concerning. The nature of open operations involves cutting wide tissues and large muscle groups. These incisions naturally cause severe pain, difficulty moving, and weeks of bed rest for the sutures to heal. In minimally invasive and technological approaches, however, there are only several openings in the body as thin as a pencil and small enough to be covered with an adhesive bandage.

Because there is no major damage to tissues and muscles, the pain patients experience after surgery is remarkably low. Most patients can go through the process using very simple and ordinary painkiller tablets without ever needing strong narcotic painkillers. Since there is no enormous surgical scar on the abdomen, you psychologically feel much more “intact.” From an aesthetic perspective, the absence of an unpleasant scar on the body is also an important factor that increases motivation for recovery.

The advantages of the early postoperative period are as follows:

• Very low pain level
• Reduced need for blood transfusion
• Rapid return of bowel movements
• Better cosmetic outcome
• Reduced risk of infection

Because the pain is mild, patients can comfortably stand up and begin walking on the evening of the operation or by the following morning at the latest. Not remaining in bed after surgery and moving early significantly reduces serious risks such as blood clot formation in the leg veins and this clot traveling to the lungs. While traditional methods require patients to remain in the hospital for days and sometimes weeks, today patients who undergo many challenging urological cancer operations can be discharged only one or two days later and sleep in their own beds at home. While returning to work and social life may take months after open surgery, with this minimally invasive method patients can return to their daily routines, walks, and working lives within an average of two to three weeks.

How Are Robotic Urology Training and Quality Standards Ensured in Türkiye?

Such an advanced system cannot create a miracle on its own. The only thing that reveals its potential is the human intelligence sitting behind the console. Anyone can sit behind the controls of a machine, but using it skillfully, safely, and at the highest performance requires very serious training and experience.

Our country is one of the few respected centers in the world that maintains very strict training standards in this specialized surgical field. Academic associations and official health authorities have established very demanding training programs that a physician must complete before being able to perform these operations. Surgeons first participate in hours of computerized simulation training. Here, just as a pilot practices emergencies in a flight simulator, they become accustomed to the machine and perfect their hand-eye coordination.

They then observe the process by assisting in countless operations under the supervision of experienced specialist instructors. No one can sit at this console alone before reaching a specific number of cases, producing scientific studies, and obtaining the required certifications from the authorities. These strict rules and disciplined fellowship training lasting many years provide the foundation for these operations to be performed in our country at international standards and with high success rates. This is an important indication that our patients are treated not only with advanced technology but also by a well-trained and well-equipped medical team.
