Laparoscopic Urology

Laparoscopic urology is a modern minimally invasive surgical method used in the treatment of kidney tumors, prostate cancer, ureteropelvic junction obstructions, and selected urological diseases by entering the body through small 0.5-1 cm incisions instead of making large cuts. This revolutionary minimally invasive approach in urological surgery allows the diseased area to be treated with minimal trauma using high-resolution cameras and delicate instruments. Offering significantly less bleeding and faster recovery compared with traditional open operations, this technique is one of today’s most reliable medical solutions. Laparoscopy, which enables patients to return to their daily lives in a short time, is one of the important treatment standards of modern urology.

What Is Laparoscopic Urology and How Does the Minimally Invasive Surgery Process Work?

This method, generally known among the public as “minimally invasive surgery” or sometimes “bloodless surgery,” is the art of reaching the targeted organ without making large skin and muscle incisions. The basic philosophy of the procedure is to achieve the highest level of recovery while causing the least damage to the body. The process begins with the patient being completely put to sleep, in other words under general anesthesia. Depending on the area to be operated on, several small incisions, a few millimeters wide and slightly larger than the tip of a pencil, are generally made in the abdominal area. Thin, tube-shaped channels called trocars are inserted through these small incisions. These channels act as a bridge between the outside world and the inside of the body, and all instruments used throughout the operation enter through these bridges.

A space is needed to see and move around the internal organs comfortably. For this reason, the abdomen is slowly inflated with carbon dioxide gas, which can easily be absorbed by the body and is routinely used in laparoscopy. After the abdomen is inflated like a balloon, a camera with a very powerful light source and a high-resolution lens at its tip is inserted through one of the opened channels. This camera illuminates all the dark and narrow areas inside and transfers the images to large, high-resolution screens in the operating room. The surgeon stands right beside the patient and controls specially designed long and thin instruments with their hands, while keeping their eyes on these screens that display the surgical field in enormous detail. The surgeon moves as if inside the patient’s body, examines millimetric tissues on giant screens, and completes the procedure with great precision. When the operation is finished, the gas inside is released, the tubes are removed, and the procedure is completed by placing hidden sutures in those small openings.

What Advantages Does Laparoscopic Urology Provide Patients Compared with Open Surgery?

One of the most difficult aspects of traditional open surgery is that the skin, thick layers of fat, and especially the abdominal muscles must be cut deeply in order to reach the internal organs. The body reacts very strongly to this situation. The cut muscles take many weeks to heal, and during this period even breathing, coughing, or getting out of bed may become a serious ordeal. In the minimally invasive method, however, the muscles are not cut; thin instruments are simply passed between them. Preserving muscle integrity significantly reduces the surgical trauma felt by the body. Thanks to camera systems that magnify tissues layer by layer, even capillaries can be clearly seen and unwanted bleeding can be prevented. Since anatomical details that are difficult to see with the naked eye occupy a much larger area on the screen, the surgical field is much cleaner and safer.

Some important advantages from which patients benefit most are as follows:

• Low pain level
• Reduced blood loss
• Rapid discharge
• Early return to work
• Small and aesthetic scars
• Low risk of infection

These advantages not only shorten the time spent in the hospital. The absence of long and deep incision scars also helps the person feel better psychologically after surgery. A person who does not see a huge scar on their body overcomes the disease more quickly psychologically. In addition, long-term problems called incisional hernias are seen much less frequently in minimally invasive surgeries than in open surgery.

What Stages Does Laparoscopic Urology Training Consist Of?

Looking at a screen while suturing or cutting tissue inside the body with long rods from the outside is not a hand-eye coordination that comes naturally to humans. The projection of the three-dimensional world onto a two-dimensional screen causes a loss of depth perception. Moreover, since the instruments enter the body through an opening, they work according to the lever principle; when the surgeon moves their hand to the right, the instrument inside moves to the left. Becoming accustomed to this reverse movement mechanism and the change in depth perception requires a long and very patient training process.

The training process does not begin directly on patients. First, hand practice is performed using closed training boxes. Surgeons thread beads onto strings inside these boxes, cut sponges, and practice suturing for hours and days on model tissues. Then virtual reality devices similar to flight simulators in the aviation industry come into play. These devices measure the surgeon’s hand movements to the millimeter, record errors, and assign scores. After reaching a certain level of mastery in the virtual environment, the period of clinical observation and assisting an experienced mentor begins. In modern medical education, even the most difficult surgeries are divided into small stages step by step. The surgeon candidate works until reaching sufficient competence at each stage and moves on to the next stage after gaining practice. This meticulous process is applied without compromise to maintain patient safety at the highest level.

Which Advanced Technologies Are Used in Laparoscopic Urology Surgeries?

The success of minimally invasive surgery is the result of combining the physician’s skill with advanced engineering marvels. In the past, every bleeding vessel in open surgery had to be tied individually with fine threads, which greatly prolonged the operation. Today, smart devices that perform this task within seconds are used. There are devices that measure the thickness of the tissue, the amount of fluid within it, and its resistance thousands of times per second, and then deliver exactly the right amount of energy to seal and cut the vessel without bleeding.

Some technologies frequently used in surgeries are as follows:

• High-resolution lenses
• Angled camera systems
• Bipolar energy instruments
• Vessel sealing devices
• Ultrasonic cutters
• Locking polymer vascular clips
• Titanium staples (Stapler)

When used correctly, these energy systems help reduce heat spread to surrounding tissues; however, because every energy device carries a risk of thermal effects, careful use is necessary. Preventing heat from spreading to the surrounding area is especially vital in regions where nerves are dense. These instruments, used under the excellent view provided by the camera, produce delicate and precise results like a brush in the surgeon’s hand. When large and vital vessels need to be cut, special tissue staplers come into play

When large and vital vessels need to be controlled, different closure systems may be used depending on the patient’s condition and the type of surgery. Locking polymer clips are special surgical materials that allow vascular or duct structures to be closed securely. For larger vascular structures or situations in which certain tissues need to be cut together, stapling systems called staplers may be preferred. These staplers suture a large vessel with three rows of titanium staples at the same time and cut it exactly through the middle, allowing a major procedure to be completed flawlessly and in a controlled manner within seconds.

What Advantages Can Laparoscopic Surgery Provide in Prostate Cancer?

The prostate gland is a highly strategic organ located at the very bottom of the pelvis, almost in one of the deepest wells of the body. The urinary canal passes through it, and it is surrounded by nerve fibers as thin and delicate as a spider’s web that provide sexual functions in men. When this organ needs to be removed from the body due to prostate cancer, the greatest challenge is to avoid damaging the vital structures around it while working in this deep well. The aim is not only to remove the cancer but also to enable the person to control urination comfortably after surgery and continue their sexual life.

In open surgery, it is quite difficult to look down into that narrow and dark area from above and see the details. However, a high-resolution camera sent inside illuminates that dark well like a stadium and projects the anatomy onto giant screens. Those tiny nerve fibers, which are difficult to see with the naked eye, appear as clearly as ropes on the screen. This clarity allows the surgeon to gently move those nerves aside and remove only the prostate. Likewise, the muscle structure responsible for urinary control is preserved with millimetric precision. In suitable cases, the success rate of surgically removing the cancerous tissue is quite high. After surgery, patients get back on their feet in a very short time, their catheters are removed early, and they return to their normal lives very quickly.

How Is the Organ Completely Removed with Laparoscopic Urology in Kidney Tumors?

When kidney cancers are concerned, if the tumor has reached a very large size or is in a dangerous location very close to the main vessels of the kidney, the kidney may need to be completely removed together with the surrounding membrane and fatty tissue. Many patients can live a completely normal, healthy, and long life with one kidney if the remaining kidney is healthy. This complete removal procedure is called radical nephrectomy. While the traditional method requires a huge incision extending from beneath the ribs to the middle of the abdomen, the minimally invasive method is much more refined.

Depending on the patient’s condition and the location of the tumor, the procedure may be performed from the front through the abdominal cavity, known as transperitoneal, or directly from the back through the lumbar region, known as retroperitoneal. Under camera guidance, the main artery and vein of the kidney are identified, sealed with safe instruments, and cut. The kidney is completely freed from the surrounding attachments. This large organ, now completely free inside, is placed into a special and durable bag called an endobag inserted through one of the openings. After the mouth of the bag is tightened, a very small, aesthetic incision is generally made in the lower abdomen, and the kidney is removed intact inside this bag. In this way, the massive muscle groups on the patient’s side are spared from being cut.

In Which Situations Is Laparoscopic Urology Preferred to Preserve the Kidney?

One of the most important goals of modern medicine is to preserve organs whenever possible. If the tumor in the kidney is relatively small and located in a suitable area, the aim is to remove only the tumorous part, almost like cutting the rotten part out of an apple, instead of sacrificing the entire kidney, while preserving the remaining healthy part. This procedure is one of the highest levels of art achieved in minimally invasive surgery.

The kidney is an organ with a very rich blood supply. If you simply begin cutting the tumor, uncontrollable bleeding will occur. To prevent this, the surgeon first identifies the main vessel carrying blood to the kidney and closes it temporarily with a clip. The blood flow to the kidney stops. From this moment onward, time becomes important in terms of preserving kidney function. This is because interrupting blood flow to the kidney for a long time may cause the kidney tissue to remain without oxygen and may negatively affect its functions. Therefore, when blood flow to the kidney is temporarily stopped, the aim is to keep this period as short as possible. In general, keeping the warm ischemia time short is important for preserving postoperative kidney functions. Within this limited period, the tumor is cut out with millimetric precision, removed, the resulting cavity is sutured rapidly with very special techniques to prevent bleeding, and the clip on the main vessel is opened to restore blood flow to the kidney. Seeing the kidney turn pink again on the screen is proof that the procedure has been completed successfully. The remaining healthy kidney tissue greatly helps preserve the patient’s kidney functions.

How Is Laparoscopic Urology Applied in Adrenal Gland Diseases?

The small but very powerful glands located directly on top of the kidneys like hats and responsible for controlling the body’s entire hormonal balance, blood pressure, and stress response are called the adrenal glands. Sometimes benign tumors or masses that cause excessive hormone production may develop in these glands. The greatest disadvantage of these glands is that they are hidden in one of the deepest and most inaccessible parts of the body, behind the ribs.

In the past, major operations causing severe trauma to the patient were performed to remove these tiny organs. Today, however, thanks to the minimally invasive method, these procedures have become almost routine. The area where the gland is located is reached directly through several small openings made in the lumbar or abdominal region. The fine vessels around the gland are sealed within seconds without bleeding using advanced energy devices, and the mass is removed inside a small bag. The operation takes a very short time, and patients are generally discharged within one or two days and return to their normal lives. Hormonal imbalance is generally brought under control in a short time, and improvement is observed in the patient’s complaints.

What Solution Does Laparoscopic Urology Offer in the Treatment of Kidney Duct Narrowing?

Urine produced by the kidney first collects in a small basin and is then carried to the bladder through a thin canal. Sometimes, due to a congenital structural problem or a factor that develops later, a severe narrowing, known as UPJ obstruction, occurs at the junction of this basin and the canal. Because the urine cannot flow downward, the kidney begins to swell, causes severe pain, and over time destroys the kidney tissue from within. This is a mechanical obstruction and cannot be corrected with medication.

The solution is to cut out and remove the narrowed, nonfunctioning section and sew the remaining healthy canal widely back to the basin. This repair, known as pyeloplasty, is performed with great surgical precision using the minimally invasive method. Using very fine threads and with the help of the enlarged image on the screen, a watertight suture is placed. During the healing process, a temporary, thin, plastic stent is inserted to prevent the newly created passage from closing and to support it. When the sutures have completely healed, this stent is removed through a very simple outpatient procedure. The accumulation in the kidney decreases, the swelling subsides, and the risk of organ loss is greatly reduced.

What Are the Possible Risks and Adverse Effects of Laparoscopic Urology Surgeries?

There is no procedure in medicine that is one hundred percent risk-free. Although minimally invasive surgery is the method that causes the least harm to the body, it naturally carries certain potential dangers. Discussing these risks transparently is very important for establishing correct expectations. Most of the time, these risks occur at very low rates and can be managed quickly by experienced teams.

Some possible conditions that may be encountered are as follows:

• Fever
• Redness at the wound site
• Urinary tract infection
• Unwanted bleeding
• Damage to surrounding tissues
• Necessity of conversion to open surgery

A large proportion of these listed conditions are temporary problems that can be resolved in a short time with simple antibiotics or fever-reducing medications. However, sometimes dense internal adhesions or unintended injuries to surrounding organs during the use of devices, and rarely vascular injuries, may occur. When such a situation is detected or when bleeding reaches a level that cannot be controlled with the minimally invasive method, the surgeon may immediately decide to discontinue the minimally invasive method and convert to conventional open surgery to ensure the patient’s safety. This is not an error or a failure; on the contrary, it is an extremely correct and necessary medical precaution taken to protect the patient’s life.

What Should Be Expected During the Recovery and Care Process After Laparoscopic Urology?

The completion of the operation means that only one stage of the process has been completed. The truly important part is helping the body recover rapidly and return to its normal state. After minimally invasive surgeries, patients generally feel a very mild ache in the abdominal area when they wake up. However, what surprises many patients is the pain they feel in the shoulder areas, which seem completely unrelated to the surgical site. This pain occurs because the gas used to inflate the abdomen during surgery stimulates the diaphragm muscle, and this stimulation is reflected to the shoulder through the nerves. As the body absorbs the gas, this sensation disappears completely on its own within a few days.

Important steps that accelerate recovery in the early period are as follows:

• Early walking
• Rapid transition to nutrition
• Deep breathing exercises
• Use of compression stockings
• Regular pain control
• Drinking plenty of fluids

Unlike open surgeries, patients are absolutely not expected to remain in bed for days. Immobility creates the conditions for the intestines to become sluggish and dangerous blood clots to form in the legs. For this reason, patients are helped to stand up immediately on the evening of surgery under the supervision of a nurse and are walked along the corridor. The more they walk, the sooner the intestines begin to function and gas can be passed. The transition to nutrition is planned according to the type of surgery and the patient’s bowel movements. Many patients begin taking liquid foods on the same evening and, if tolerated, can often eat normal meals the next day. The risk of clots is reduced through special stockings worn on the legs and blood-thinning treatments. This rapid mobilization brings the discharge date forward by several days.
