Percutaneous Nephrolithotomy (PCNL): A Comprehensive Guide (Hindi)

Percutaneous Nephrolithotomy, commonly known as PCNL, is a revolutionary procedure in the field of urology, especially for patients suffering from kidney stones. This minimally invasive technique has transformed the way large kidney stones are treated, offering a less painful and more effective alternative to traditional methods.

What is Percutaneous Nephrolithotomy (PCNL)?

PCNL is a surgical procedure used to remove large or complex stones from the kidney. It involves making a small incision in the back and using a nephroscope to break and extract the stones. The process is highly efficient for stones that are too large to pass through the urinary tract or cannot be treated with other non-invasive methods.

The PCNL Procedure: How It Works

The procedure starts with a small puncture in the patient’s back, directly into the kidney. A nephroscope is inserted through this pathway, allowing the surgeon to visualize and fragment the stones. The fragments are then removed through the same incision. The precision and control offered by PCNL significantly reduce the risk of leaving any stone fragments behind.

Benefits of PCNL

  1. Minimally Invasive: Unlike traditional surgeries, PCNL involves a smaller incision, leading to quicker recovery and less post-operative pain.
  2. Highly Effective for Large Stones: PCNL is particularly effective for ‘staghorn’ stones, which are large stones that occupy a significant portion of the kidney.
  3. Reduced Risk of Complications: The procedure has a lower risk of complications compared to open surgery.

Considerations and Risks

While PCNL is a safe procedure, it’s essential to understand the associated risks:

  1. Bleeding: As the kidney is a highly vascular organ, there’s a slight risk of bleeding.
  2. Infection: The procedure can potentially lead to infections due to the presence of bacteria in the stones.
  3. Post-Operative Care: Patients typically require a short period of bed rest to ensure proper healing.

PCNL is often recommended in several scenarios, including:

  1. Size of the Stone: Stones larger than 1.5 – 2 cm, especially staghorn stones, are ideal candidates for PCNL.
  2. Anatomical Variations: Abnormal kidney positions or shapes might necessitate PCNL.
  3. Previous Surgical Interventions: Patients who have undergone multiple unsuccessful stone removal surgeries may benefit from PCNL.

Patient Perspective: Life After PCNL

Patients typically experience significant relief post-PCNL. Issues like pain, urinary blockages, and discomfort are often resolved. While there is a recovery period involved, most patients can resume normal activities within a week, with gradual improvement in their condition.

Cost Considerations

The cost of PCNL can vary based on factors like the complexity of the case, the healthcare facility, and the geographic location. However, it is generally more cost-effective than traditional surgery, especially when considering the reduced recovery time and lower risk of complications.


PCNL represents a significant advancement in the treatment of large kidney stones. With its minimally invasive nature, high success rate, and reduced recovery time, it offers a preferable alternative to traditional surgeries. If you or a loved one is considering PCNL, consult with a qualified urologist to understand the procedure, benefits, and risks tailored to your specific condition.
