What Is Pyeloplasty Surgery and What Are Its Advantages?

Pyeloplasty surgery is a surgical method applied to repair narrowings that occur in the area connecting the kidney to the ureter (urinary canal). It is generally performed to eliminate congenital or subsequently developed urinary tract obstructions.

Thanks to this surgery, the kidney's urine flow is corrected, and the risk of pain and infection is reduced. Today, laparoscopic and robotic pyeloplasty techniques are preferred for their smaller scars and faster recovery processes.

What Is Pyeloplasty Surgery?

Pyeloplasty is the surgical removal of the obstruction that prevents the passage of urine from the kidney to the bladder.

This operation is applied in the condition known as ureteropelvic junction obstruction (UPJ obstruction). In this condition, urine cannot maintain its normal flow from the kidney to the bladder and begins to accumulate in the kidney. The surgeon removes the obstructed section and allows the urine to pass again to the bladder.

Urine is collected in the renal pelvis of the kidney and transported to the bladder through the ureter. An obstruction occurring at the ureteropelvic junction where the kidney and ureter meet can lead to kidney pain, urinary tract infections, and kidney damage. Pyeloplasty surgery is an effective treatment method preferred to prevent such complications.

What Are the Advantages of Pyeloplasty Surgery?

Pyeloplasty operation can be applied using open surgery, laparoscopic, or robotic surgical techniques. Each method has its own specific advantages and some limitations.

With pyeloplasty, the obstruction is eliminated, and complaints such as pain and recurring urinary tract infections are largely reduced. In addition, progressive damage to the kidney is prevented and the functional capacity of the organ is preserved.

The advantages of pyeloplasty surgery are listed below:

• Correction of urine flow
• Preservation of kidney function
• Minimally invasive surgical options
• Shorter hospital stay
• Faster recovery
• Reduced post-operative pain
• Small incision and aesthetic appearance
• High success rate

What Are the Types of Pyeloplasty Surgery?

The technique to be applied in pyeloplasty surgery is determined based on the patient's general health status, the degree and location of the obstruction, and the surgeon's experience. Each method has its own specific advantages and limitations.

The types of pyeloplasty surgery are listed below:

• Open Pyeloplasty
• Laparoscopic Pyeloplasty
• Robotic Pyeloplasty
• Endopyelotomy

Open Pyeloplasty

In open pyeloplasty surgery, a wide incision is made in the abdominal area to reach the kidney and ureter. The narrowed or obstructed ureteropelvic junction (UPJ) region is removed and the remaining healthy tissues are reconnected to correct urine flow. This method may be preferred in complex cases or when closed surgery is not appropriate.

Laparoscopic Pyeloplasty

Laparoscopic Pyeloplasty is a minimally invasive surgical method performed with a camera and special surgical instruments inserted through small incisions. The surgeon views the operation area through the laparoscope and performs the procedure robotically or manually. This method offers advantages such as less pain, shorter hospital stay, and faster recovery compared to open surgery.

Robotic Pyeloplasty

Robot-assisted Pyeloplasty is an advanced version of the laparoscopic technique. The surgeon performs the procedure with high precision by controlling robotic arms. The robotic system provides the opportunity for more controlled and safer intervention in narrow surgical areas. This method stands out with its short recovery time and high success rate due to its minimally invasive features.

Endopyelotomy

Endopyelotomy is a minimally invasive procedure applied through a thin ureteroscope inserted through the urethra. The surgeon widens the passage of urine by making small incisions in the obstructed area. This method can be an effective alternative in selected ureteropelvic junction (UPJ) stricture cases and in patients for whom open or laparoscopic surgery is not appropriate.

How Is Pyeloplasty Surgery Performed?

Laparoscopic pyeloplasty is a minimally invasive surgical method performed under general anesthesia. A camera and special surgical instruments are inserted through small incisions opened in the abdominal area. The surgeon detects and repairs the narrowing at the kidney outlet using high-resolution images obtained from this camera. The operation time generally ranges from 2 to 3 hours.

The instruments used during laparoscopic pyeloplasty have advanced surgical technology. These devices allow the surgeon to work with millimetric precision. The high-resolution laparoscopic camera helps to clearly view the surgical area and increases the safety of the surgical intervention.

How Long Does Pyeloplasty Surgery Take?

Pyeloplasty surgery is a surgical procedure performed to eliminate narrowing between the kidney and the urinary canal, and it usually takes on average two to three hours depending on the scope of the operation.

Who Is Pyeloplasty Surgery Performed On?

Approximately one in every 1,500 people is born with congenital ureteropelvic junction obstruction. If this obstruction does not resolve on its own within 18 months in a child, doctors may recommend pyeloplasty surgery.

In addition, obstructions that subsequently develop in children, adolescents, and adults may also require pyeloplasty. Surgical intervention may be required in cases where kidney function is impaired, urine is accumulating in the kidney, or pain or recurring infections are observed.

If hydronephrosis, i.e., kidney swelling, is detected in imaging methods (ultrasound, CT, or MRI), doctors may suspect UPJ obstruction.

Which Doctor Performs Pyeloplasty Surgery?

Pyeloplasty surgery is performed by urology surgery to correct the narrowing or obstruction at the junction of the kidney pelvis and ureter to ensure proper urine flow.

Frequently Asked Questions About Pyeloplasty Surgery

Below are frequently asked questions and answers about pyeloplasty surgery.

Is Sexual Activity Possible After Pyeloplasty Surgery?

Full recovery after pyeloplasty surgery generally takes 10-14 days, and sexual intercourse can be resumed 2-4 weeks later.

What Are the Complications After Pyeloplasty Surgery?

Possible complications after pyeloplasty surgery include infection, bleeding, scarring at the wound site, urine leakage, need for stent removal, and in rare cases, recurrence of obstruction requiring additional surgery.
