Percutaneous Nephrolithotomy (PCNL) Surgery, Procedure & Cost

Why Choose PACE Hospitals for PCNL Surgery?

Percutaneous Nephrolithotomy (PCNL) Types

Percutaneous Nephrolithotomy (PCNL) procedure has various types, each offering specific benefits based on the size of the instruments used and the patient's position. These types include:

Based on the size of the instruments 

PCNL types are classified by instrument size. They include: 

• Standard PCNL 
• Mini PCNL 
• Ultra-mini PCNL 
• Micro PCNL
  
  

Standard PCNL 

Standard Percutaneous Nephrolithotomy (PCNL) is the conventional and widely accepted minimally invasive surgical procedure used to remove large or complex kidney stones by creating a small tract through the skin directly into the kidney and using instruments (usually 24–30 French) to break up and extract the stones. It is done under anesthesia with imaging guidance, has higher stone-free rates for stones that can't be treated with less invasive methods, and has mostly replaced open surgery for large kidney stones.

Mini PCNL 

Mini Percutaneous Nephrolithotomy (Mini-PCNL) is a surgical procedure that removes kidney stones with very little damage to the body. It uses a smaller incision and fine instruments (usually less than 20 French) than a regular PCNL. This method removes stones effectively while causing less damage to tissue, less bleeding, and a shorter recovery time. Mini-PCNL is often a safer alternative for treating many types of kidney stones, offering similar success rates as the standard method but with fewer complications.

Ultra-mini PCNL 

Ultra-mini Percutaneous Nephrolithotomy (Ultra-mini-PCNL) involves an even smaller tract (about 11–13 French) and thinner scopes than mini PCNL, making it less invasive for removing medium-sized (often ≤2 cm) kidney and upper ureteric stones. It has been shown to reduce blood loss, pain, and length of hospitalization compared with standard PCNL in appropriately selected stones.

Micro PCNL

Micro Percutaneous Nephrolithotomy (Micro PCNL) uses very small instruments and access tracts (about 4.8–10 French) that are meant to be as non-invasive as possible. This is especially helpful for smaller stones (up to about 15 mm). It also causes less damage to tissue and bleeding than larger PCNL techniques, while continuing to receive good stone-free outcomes in some patients.

Based on the patient's position

There are two main types, based on how the patient is positioned during the procedure. They include: 

• Prone PCNL
• Supine PCNL
  
  

Prone PCNL

The patient lies face down (on the abdomen) during the procedure. It is the traditional approach and provides better access to the kidney, especially for large or complex stones.

Supine PCNL

The patient lies on their back (face up) during surgery. It allows easier anesthesia management and may offer improved comfort and shorter procedure time in selected cases.

Indications of PCNL

PCNL is recommended for treating large or complicated kidney stones that cannot be managed with less invasive methods. It is used when other treatments fail or are unsuitable for the patient's condition. The following are the Percutaneous Nephrolithotomy indications:

• Large kidney stones
• Staghorn calculi
• Treatment-resistant stones
• Lower-pole stones
• Obstruction or complications
  
  

Large kidney stones

PCNL is recommended for stones larger than 2 cm, as they are less likely to pass on their own and cannot be effectively treated with non-invasive methods like shock wave lithotripsy. PCNL allows direct access to remove these stones efficiently.

Staghorn calculi

These are large, branched stones that occupy multiple parts of the kidney. Due to their complexity and size, they cannot be treated with less invasive methods, making PCNL the preferred treatment for complete stone removal.

Treatment-resistant stones

When kidney stones do not respond to shock wave lithotripsy or ureteroscopy, PCNL is recommended. This method ensures the complete removal of stones that are resistant to less invasive treatments.

Lower-pole stones

Stones present in the lower pole of the kidney are difficult to treat with non-invasive techniques due to their position. PCNL provides a direct approach for more effective stone removal in these locations.

Obstruction or complications

Stones causing urinary obstruction, infections, or kidney damage require prompt removal. PCNL is used to relieve obstruction and prevent further complications, such as kidney damage or infections.

Contraindications of PCNL

Certain conditions make Percutaneous Nephrolithotomy (PCNL) unsafe, and it should be avoided in those cases. The following are the PCNL contraindications:

• Active urinary tract infection (UTI)
• Uncorrected bleeding disorder / anticoagulant therapy
• Pregnancy
• Tumor in the access tract area/malignant kidney tumor
• Poor cardiopulmonary reserve or high risk anesthesia
  
  

Active urinary tract infection (UTI)

PCNL should not be performed if there is an active urinary tract infection, as manipulating the kidney can cause the infection to spread and lead to sepsis. Antibiotic treatment must resolve the infection before surgery.

Uncorrected bleeding disorder / anticoagulant therapy

Patients with bleeding disorders or on anticoagulant therapy have an increased risk of excessive bleeding. These conditions must be corrected, or anticoagulants must be managed appropriately before the procedure to avoid complications.

Pregnancy

PCNL is generally contraindicated during pregnancy due to the risks of radiation exposure to the fetus from fluoroscopic X-ray imaging. If the procedure is absolutely necessary, a thorough multidisciplinary evaluation is required, and alternative methods like ureteroscopy may be considered.

Tumor in the access tract area/malignant kidney tumor

A tumor in the planned access route or in the kidney can make PCNL unsafe, as the procedure may spread malignant cells or cause severe bleeding. The area should be evaluated to rule out malignancy before proceeding.

Poor cardiopulmonary reserve or high risk anesthesia

Patients with severe heart or lung conditions, or those who cannot tolerate anesthesia, face high risks during PCNL. These patients may require alternative treatments or adjustments in the surgical procedure to reduce risk.

Considerations in PCNL

Several factors must be considered before performing Percutaneous Nephrolithotomy (PCNL) to ensure the procedure's safety and effectiveness. It includes:

• Imaging like CT or ultrasound before the procedure, is crucial for identifying stone size, location, and kidney structure to plan safe access and avoid complications.
• Patient comorbidities, including renal function and cardiovascular conditions, should be carefully assessed to determine the surgical risk and suitability for PCNL.
• Anesthesia considerations in PCNL are based on the patient's health, surgery duration, and positioning needs, along with the requirement for immobility during the procedure.
• Careful renal access is critical to minimize injury to surrounding organs and blood vessels, requiring accurate puncture and tract dilation.
• It is important to drain the kidneys after surgery using a nephrostomy tube to make sure they function properly and get rid of any residual fragments.
• It is crucial to control infection, and appropriate antibiotics should be given to stop infection after surgery.
• Follow-up imaging is done to see if the stones have been cleared and to look for any residual fragments after the procedure.
• Pain management strategies are adjusted based on the patient's individual needs and the surgical complexity.
• Metabolic testing may be required for patients with recurrent stones to help prevent future stone formation.
  

Advantages of PCNL

Percutaneous Nephrolithotomy (PCNL) is a minimally invasive surgery for removing large or complex kidney stones, with several advantages over traditional surgery. It includes:

• High Stone-Free Rate
• Minimally Invasive
• Shorter Recovery Time
• Effective for Larger Stones
• Fewer Complications
  
  

High Stone-Free Rate

PCNL is highly effective in completely removing large or complex kidney stones, providing a high success rate compared to non-invasive treatments like shock wave lithotripsy. This leads to fewer stone fragments and reduces the likelihood of requiring additional procedures.

Minimally Invasive

The procedure makes small incisions, which indicates that less damage is done to nearby organs and tissue. This not only reduces pain after surgery but also lowers the chance of infection and scarring, making it a safer choice.

Shorter Recovery Time

Because PCNL is less invasive than open surgery, patients experience faster recovery, shorter hospital stays, and a quicker return to daily activities, improving overall quality of life post-surgery.

Effective for Larger Stones

PCNL is especially effective for large stones (larger than 2 cm) or those that are difficult to treat with other methods, such as shock wave lithotripsy. It can also treat staghorn calculi and stones in the lower pole of the kidney.

Fewer Complications

PCNL generally carries a lower risk of complications like bleeding, infection, and kidney injury compared to traditional open surgery, due to its minimally invasive nature. This leads to safer outcomes and less time spent in the hospital.

PCNL Procedure Steps

The following are the percutaneous nephrolithotomy (PCNL) procedure steps:

Before the Procedure

• Imaging and Evaluation: Imaging tests like CT, ultrasound, or X-ray are done to evaluate the size, location, and type of kidney stones. Blood tests are done to evaluate kidney function and overall health, and antibiotics may be given to prevent infection.
  
• Anesthesia Assessment: The patient undergoes an assessment to determine the best anesthesia option, typically general anesthesia, to ensure comfort during the procedure.
  
• Preparation and Positioning: The patient is lying in a prone position (lying face down) to allow access to the kidney from the back. The surgical site is sterilized to minimize the risk of infection.
  
  

During the Procedure

• Incision and Access: A small incision is made in the patient’s back. Using fluoroscopy or ultrasound, the surgeon inserts a needle to create a path to the kidney. This allows for the placement of a guidewire and dilation of the tract to accommodate the necessary instruments for stone removal.
• Stone Removal: A nephroscope (a small tube with a camera) is inserted to locate and visualize the stones. Various techniques, like laser lithotripsy or ultrasonic devices, are used to break the stones into smaller pieces, which are then removed through the access tract using specialized instruments.
• Draining: A nephrostomy tube may be placed into the kidney to allow urine to drain out and promote healing. This tube helps prevent infection and obstruction, and also facilitates the removal of any remaining stone fragments during the recovery period.
  
  

After the procedure

• Recovery and Monitoring: After the procedure, the patient is monitored in a recovery room to make sure they are stable. Pain management is given, and vital signs like blood pressure, heart rate, and oxygen levels are checked on a regular basis. Before the patient is discharged, the medical team ensures they are completely conscious and comfortable.
• Follow-Up Imaging: After surgery, CT scans or X-rays are done to make sure that all the stones were taken out and that the kidney is working properly. This imaging checks for any remaining stone fragments and any possible problems, such as bleeding or infection.
• Discharge and Care Instructions: The patient is discharged once they get stable, with wound care instructions and advised on activity restrictions to avoid stress on the recovery site. The patient is also instructed on signs of complications like infection or bleeding, and is scheduled for a follow-up visit.

PCNL Complications

Although PCNL is effective, it carries potential complications such as bleeding, infection, and injury to surrounding organs. The following are the PCNL surgery complications:

• Bleeding
• Infection
• Incomplete Stone Removal
• Injury to Kidney or Other Organs
  
  

Bleeding

During or after surgery, PCNL can cause bleeding around the kidney because the surgery was performed in a certain way. This might lead to blood loss, which might require a blood transfusion or further treatment to stop the bleeding and ensure a complete recovery. Managing blood loss is essential for a safe recovery.

Infection

Even though antibiotics are used to lower the risk, there is still a chance of getting an infection after PCNL, such as a urinary tract infection or sepsis. Infections can cause fever, pain, or discomfort, and if they aren't treated, they could lead to serious problems that require further treatment, such as antibiotics or drainage.

Incomplete Stone Removal

PCNL works very well, but a few pieces of stone may still be present after the surgery. These residual stones can cause signs or conditions to reappear, and patients may require additional treatments, like more PCNL sessions or other methods, to get rid of the remaining stones.

Injury to Kidney or Other Organs

PCNL may damage the kidney or nearby organs, like the bowel, spleen, liver, or lungs, but this is not common. This is because it requires access to the kidney. These injuries can happen when the needle or nephroscope is placed in, and additional surgery may be required to repair any damage.

PCNL Surgery Recovery Time

After Percutaneous Nephrolithotomy (PCNL), most patients only require staying in the hospital for 1–2 days for monitoring. After that, they usually get back to light daily activities within 1–2 weeks. Depending on the patient's health and the difficulty of the procedure, full recovery could take from two to four weeks. During this time, patients are advised not to do excessive activities and should follow their doctor's instructions. Follow-up imaging may be done to make sure the stone has been completely removed, and the process of healing is progressing properly.

Frequently Asked Questions (FAQs) on PCNL Surgery

What is PCNL surgery?

What is the recovery time for PCNL surgery?

The recovery time for PCNL surgery is generally shorter than after traditional surgery, with most patients requiring a hospital stay of 1–3 days, resuming their daily activities within 1–2 weeks, and reaching complete recovery over the following few weeks, depending on their health condition.

How painful is PCNL surgery?

PCNL surgery is not painful while performing the procedure because of anesthesia. Even after surgery, patients may experience mild to moderate pain around the back or incision site, which can be treated with medications. Most people can manage the pain as it gradually reduces within a few days, allowing them to return to normal activities soon.

Who performs PCNL?

Overall, PCNL is chosen when other less invasive methods are not effective.

A trained urologist who specializes in treating kidney stones performs PCNL. The procedure takes place in a hospital and utilizes special instruments to gain access to the kidney. Most of the time, it is done under anesthesia to make sure the patient is comfortable. It is important to have an experienced urologist perform the stone removal safely and effectively. A supporting medical team assists throughout the procedure.

Does PCNL damage the kidneys?

Yes, PCNL (Percutaneous Nephrolithotomy) can cause some degree of damage to the kidney because the procedure includes puncturing and dilating the kidney to remove stones, which may lead to temporary or, rarely, lasting renal damage as a surgical complication. Studies show that most patients' kidney function remains the same or gets better after stones are removed. However, creating an access tract always carries some risk of damaging the renal tissue, and in a small number of cases, there can be a measurable loss of function or acute kidney injury.

Does PCNL require stitches?

Yes, PCNL (percutaneous nephrolithotomy) usually needs stitches to close the cut in the skin, which is usually only about 1 cm long. The incision is made so that the kidney can be accessed, and stitches are used to close it after the procedure is completed. In some cases, dissolvable stitches may be used. In more modern methods, adhesive glue may even be used instead of stitches to close the wound. The need for stitches depends on the size of the incision and the surgical approach.

Is a stent necessary after PCNL surgery?

After a percutaneous nephrolithotomy (PCNL) procedure, a stent is commonly placed to ensure that urine is draining properly from the kidney. This is because the surgery can lead to swelling or blockages in the renal system. The stent usually remains in place for a few days to a week, which helps the kidney heal and reduces the chance of complications like urinary retention or infection. However, the need for a stent can depend on the specifics of the surgery and individual patient factors.

What is the difference between PCN and PCNL?

The main difference between PCN (Percutaneous Nephrostomy) and PCNL (Percutaneous Nephrolithotomy) is that PCN is mainly used to drain the kidney to relieve an obstruction or infection. This usually involves placing a catheter. PCNL, on the other hand, is a surgical procedure that is used to remove large or complicated kidney stones. PCN helps with urinary drainage and pain relief, while PCNL is used to remove stones when other methods, like shock wave lithotripsy, are ineffective.

What type of diet should be followed after PCNL surgery?

Does PCNL use radiation?
