What is Robotic Pyeloplasty? Who is it Applied to? What are its Advantages?

Narrowing that obstructs urine flow from your kidney can negatively affect your health. Robotic pyeloplasty is a minimally invasive surgical method that treats such narrowings using modern technology. With this procedure performed through small incisions, long hospital stays and painful recovery processes are no longer necessary.

Ureteral narrowing can lead to serious problems such as kidney enlargement, pain, and infection. Pyeloplasty surgery is performed to eliminate this narrowing and typically lasts 1.5 to 3 hours. When performed using robotic techniques, the surgeon can make more precise interventions with a three-dimensional imaging system, and patients can usually be discharged within just 1 to 3 days.

In this article, we will clearly explain what robotic pyeloplasty is, who it is applied to, and the advantages it offers. You will also learn how this procedure is performed and that it is a suitable option for many patients, including children over the age of 1.

What are Pyeloplasty and Robotic Pyeloplasty?

Narrowings that occur at the connection between the urinary tract and the kidney can seriously affect your health. Pyeloplasty surgery is an important treatment method for solving kidney and urinary tract problems. In this section, you will understand what pyeloplasty and robotic pyeloplasty are and how they are applied.

What does pyeloplasty mean?

Pyeloplasty is a surgical method applied to repair the narrowings that occur in the area connecting the kidney to the ureter (urinary tract). This connection point is called the ureteropelvic junction (UPJ). It is usually performed to relieve congenital or acquired urinary tract obstructions.

When urine cannot continue its normal flow from the kidney to the bladder, it begins to accumulate in the kidney. Over time, this condition can lead to problems such as kidney enlargement (hydronephrosis), pain, and infection. In pyeloplasty surgery, the surgeon removes the obstructed part to allow urine to pass back into the bladder. This restores urine flow from the kidney, reducing pain and the risk of infection.

What is the method of robotic pyeloplasty?

Robotic pyeloplasty is an advanced version of laparoscopic technique. In this method used for treating kidney channel narrowing, the surgeon controls robotic arms to perform the procedure with high precision.

This procedure is typically performed using a medical technology called the Da Vinci Robot. This system consists of an operator console and robotic arms. The surgeon can clearly see the surgical area thanks to three-dimensional and high-resolution images from the robot’s console. This technological system allows the surgeon to intervene more controlled and safely in narrow spaces.

The success rate of the robotic pyeloplasty method is around 95%. This procedure, which is performed by passing through the membranes surrounding the intestines in the abdominal area, repairs the kidney outlet with millimeter-level stitches.

What are the differences from traditional surgery?

Robotic pyeloplasty offers many advantages over traditional open surgery:

• Minimal invasive approach: Robotic pyeloplasty is performed with smaller incisions (8-13 mm) compared to open surgery. This results in less tissue damage.
• 3D imaging: The robotic system provides a three-dimensional and stable image. This allows the surgeon to make much more precise interventions.
• Rapid recovery: Postoperative pain is less compared to open surgery, and recovery is faster.
• Short hospital stay: Patients treated with robotic methods can be discharged in a shorter time.
• Aesthetic advantage: Thanks to small incisions, the patient completes the surgical process with a more aesthetic appearance.

At the same time, the robotic surgical system has a total turning capacity of 540 degrees with 180 degrees of wrist movements, which provides a significant advantage in surgical procedures in narrow spaces.

In conclusion, robotic pyeloplasty is a modern surgical method used in the treatment of urinary tract narrowing with a high success rate. Thanks to the advantages it offers over traditional surgery, it provides treatment opportunities that minimally affect patients’ quality of life.

In Which Situations is Robotic Pyeloplasty Applied?

Robotic pyeloplasty surgery is an effective treatment option for various urinary tract problems. This method is particularly preferred for narrowings occurring at the connection between the kidney and the ureter. So, in which situations is this modern surgical technique used?

Congenital urinary tract narrowing

One of the most common causes of urinary tract narrowings is congenital structural issues. This condition occurs in 1 out of every 1500 children and is usually caused by narrowing at the point where the renal pelvis connects with the ureter. Nowadays, most of these congenital narrowings can be detected early thanks to ultrasound checks performed during pregnancy. This narrowing that occurs during kidney development is one of the primary indications for robotic pyeloplasty.

Obstructions due to urinary stones

Stones that form in the urinary tract can lead to narrowing and obstruction over time. Especially stones that form within the ureter or fall from the kidney to the ureter can cause tissue damage during their passage. This damage can create scar tissue during the healing process, leading to narrowing in the urinary tract. If obstructions due to urinary stones are not treated, they can cause continuous pressure increase in the kidney and deterioration of kidney functions over time. In this case, robotic pyeloplasty can eliminate the narrowing and restore normal urine flow.

Narrowings occurring after previous surgeries

Narrowings in the urinary tract can occur after previous surgical procedures in the kidney, ureter, or bladder area. Especially injuries to the ureter during surgeries such as hysterectomy, bladder, or prostate surgeries can pave the way for narrowing during the healing process. Additionally, tissue damage that occurs during previous operations can create narrowings that can obstruct urine flow. In such cases, robotic pyeloplasty provides a solution to the problem with a minimally invasive approach.

Recurrent urinary tract infections

Constantly recurring urinary tract infections can cause inflammation and narrowing in the urinary tract over time. Recurrent urinary tract infection is defined as having at least two urinary tract infections within six months or three times within a year in women. If this condition is not treated, the infection can reach the kidneys, leading to the development of pyelonephritis, which can seriously affect kidney functions. Robotic pyeloplasty can eliminate the narrowings that cause recurrent infections, preventing the formation of infections.

Formation of hydronephrosis in the kidney

Hydronephrosis is defined as abnormal enlargement in the kidney’s urine collection system. This condition is one of the most important indicators that urine flow from the kidney to the bladder is obstructed. Accumulated urine in the kidney due to narrowing in the ureter can increase kidney internal pressure over time, leading to thinning of kidney tissue and loss of function. In advanced hydronephrosis, kidney functions can be irreversibly impaired. Therefore, in patients where continuous hydronephrosis formation is detected in the kidney, robotic pyeloplasty is an important treatment option to preserve kidney functions.

In conclusion, robotic pyeloplasty is an effective surgical method that can be applied in both congenital and acquired urinary tract narrowings, in the presence of hydronephrosis, and in patients with recurrent urinary tract infections.

How is Robotic Pyeloplasty Surgery Performed?

Robotic pyeloplasty, one of the most impressive applications of modern surgery, requires a precise and controlled process. This surgery, performed to eliminate urinary tract narrowing, consists of several stages and usually offers a short recovery process.

General anesthesia and preparation process

Before robotic pyeloplasty, doctors evaluate the patient’s overall health status. In this process, various tests and imaging methods are used to determine the extent of the narrowing. At the same time, the patient’s suitability for anesthesia and surgery is also checked.

When the day of surgery arrives, the procedure is performed under general anesthesia. This means you will be completely asleep during the surgery and will not feel anything. After anesthesia is administered, your body is prepared for the procedure, and the necessary positioning for robotic surgery is done.

Surgical intervention with robotic system

After anesthesia, the surgeon makes small incisions of 8-13 mm in your abdominal area. These incisions are used to place the robotic arms and cameras. Thanks to the robotic system, the surgeon controls the surgery from a remote console.

In robotic pyeloplasty, the surgeon removes the narrowed area and reconnects the ureter (urinary tract) to the kidney. During the operation, the doctor performs the procedure with three-dimensional high-resolution images from the robot’s console. This technology provides the surgeon with great precision and control even in narrow spaces.

Placement of stent and closure of incisions

After the urinary tract is reconnected to the kidney during the surgery, a thin plastic tube (stent) is usually placed to support healing. This stent prevents urine obstruction due to swelling that may occur in the urinary tract and helps the new connection heal properly.

This device, also known as a Double-J stent, has one end in the kidney and the other end in the bladder. This ensures that urine can flow easily from the kidney to the bladder. After the procedure is completed, the surgical incisions are carefully closed.

Surgery duration and hospital stay

Robotic pyeloplasty surgery typically lasts 1.5 to 3 hours. However, this duration may vary depending on the severity of the narrowing and the surgeon’s experience. Robotic surgical systems can shorten the overall surgery time by performing the procedure more precisely and quickly.

The hospital stay after surgery is quite short. Patients are usually discharged within 1-2 days. In the first days after surgery, mild pain and a small amount of blood in the urine may be observed, but these are part of the normal recovery process.

The placed stent usually remains in place for 2-6 weeks to ensure the success of the procedure and is then removed by a urology specialist. Most patients can return to their daily lives 1-2 weeks after surgery. Following your doctor’s recommendations during this process will positively affect the recovery process.

What are the Advantages of Robotic Pyeloplasty?

Robotic surgical technology offers many important advantages to patients undergoing pyeloplasty operations. This innovative method provides various benefits compared to traditional open surgeries, making it a preferred option for both doctors and patients. Here are the main advantages of robotic pyeloplasty:

Minimal invasive approach

Robotic pyeloplasty is less invasive compared to traditional open surgeries. While open surgery requires large incisions, the robotic method only involves making small holes of 8-13 mm in the abdominal area. This minimal invasive approach means less intervention to your body.

The surgeon performs the surgery using robotic arms placed through these small holes. This results in less tissue damage in your body and a more comfortable recovery process after surgery.

Less pain and faster recovery

Robotic pyeloplasty performed with small incisions significantly reduces postoperative pain. This also decreases the need for pain medication. Additionally, the hospital stay is shorter compared to traditional methods.

Patients can generally return to their daily lives more quickly after robotic pyeloplasty. While the recovery process is long in open surgery, with the robotic method, you can start your normal activities much faster.

Less blood loss and risk of infection

During robotic pyeloplasty, thanks to high precision and clear vision, damage to blood vessels and tissues is minimized, significantly reducing blood loss. Less blood loss decreases the need for blood transfusions and speeds up the recovery process.

Moreover, small incisions also reduce the risk of infection. Robotic surgery performed under more sterile conditions compared to open surgery also reduces the risk of wound healing problems.

Aesthetic advantage with small incisions

One of the most important advantages of robotic pyeloplasty is the aesthetic results after surgery. Instead of large surgical scars, small incision marks remain, providing a more aesthetic appearance.

Especially, instead of the large surgical scars left by open surgery, robotic pyeloplasty results in much less noticeable scars on your body. This is a significant advantage for patients who are concerned about their physical appearance.

High precision with 3D imaging

The three-dimensional imaging system used in robotic pyeloplasty provides the surgeon with an enlarged view of the surgical area with depth perception. The surgeon can see tissues, blood vessels, and nerves in more detail thanks to images enlarged up to 10 times.

The high-resolution 3D images provided by the Da Vinci Robot offer excellent magnification even in narrow spaces. Thus, a success rate of up to 95% is achieved in robotic pyeloplasty procedures. Additionally, since robotic arms do not tremble, a safer and more precise surgical intervention than human hands is possible.

In conclusion, robotic pyeloplasty is a modern surgical method that offers less pain, shorter recovery time, lower complication risk, and better cosmetic results compared to traditional methods.

Who is Suitable for Robotic Pyeloplasty?

Robotic pyeloplasty is not suitable for every patient but is an ideal treatment option for specific patient groups. Identifying the right patients who can benefit the most from surgical intervention is crucial for successful outcomes. In this section, we will examine in detail which patients robotic pyeloplasty can be applied to.

Children over 1 year old and adults

Robotic pyeloplasty is generally a suitable surgical method for children aged 1 and older as well as all adult patients. Particularly, younger patients and individuals in good general health can benefit the most from this method.

There are special points to consider regarding robotic surgery for children. In particular, in small children and infants, intra-abdominal pressure is maintained at around 10 mm Hg, and the abdomen can hold a limited amount of gas. However, robotic pyeloplasty is a suitable option for patients with no age restrictions and in good general health.

Individuals suitable for general anesthesia

Since robotic pyeloplasty is performed under general anesthesia, patients must be suitable for general anesthesia. A detailed health assessment is conducted before surgery, and the risk of anesthesia is evaluated.

In elderly patients or individuals with additional health issues, the risks and benefits of the surgery should be carefully evaluated. Generally, patients without serious other health problems are more suitable candidates for robotic pyeloplasty.

Those with recurrent narrowing complaints

Patients with recurrent UPJ (ureteropelvic junction) narrowing complaints form an important patient group for robotic pyeloplasty. This is especially preferred in patients who have previously been treated surgically or endoscopically but have recurrent narrowing. These patients may undergo “REDO pyeloplasty.”

Patients who do not benefit from endoscopic treatments (endopyelotomy, balloon dilation) are also suitable candidates for robotic pyeloplasty. In the presence of ongoing hydronephrosis after primary surgical or endoscopic treatment, the indication for REDO pyeloplasty arises if drainage disorders or loss of function are detected in scintigraphic examinations.

Patients suitable for minimally invasive surgery

Minimally invasive surgical methods may not be suitable for every patient. Robotic pyeloplasty is especially preferred for patients who are suitable for surgical intervention with minimally invasive methods. Technical difficulties may arise in obese individuals or those who have previously undergone abdominal surgery.

Additionally, if there is excessive swelling in the kidney (advanced hydronephrosis) or if there are crossed vessels at the level of UPJ narrowing, the robotic surgical method is preferred. Kidney function must not be completely lost; different treatment options may be considered for patients with severe kidney failure.
