What is PCNL Surgery?

PCNL (Percutaneous Nephrolithotomy) is a minimally invasive surgical technique to remove large or complex kidney stones that cannot be treated with less invasive methods like shock wave lithotripsy or ureteroscopy. It is particularly effective for stones larger than 2 cm, staghorn stones, or those resistant to other treatments. By accessing the kidney directly through a small incision in the back, PCNL allows for precise stone removal while minimising damage to surrounding tissues.

When is PCNL Recommended?

  • Kidney stones too large to pass naturally or through non-surgical methods
  • Stones causing severe pain, infection, or obstruction in the urinary tract
  • Other treatments have failed or are not suitable due to stone size, location, or composition
  • Recurrent kidney stones or anatomical issues affecting urine flow

The PCNL Procedure: Step-by-Step

Performed under general anaesthesia in a sterile operating environment:

  1. 1
    Preparation: Patient positioned; imaging guidance (X-ray/ultrasound) locates the stone accurately.
  2. 2
    Access Creation: A small incision (~1 cm) is made in the back. A needle enters the kidney's collecting system, followed by tract dilation.
  3. 3
    Stone Removal: A nephroscope visualises the stone, which is fragmented using laser, ultrasound, or pneumatic tools and removed or suctioned out.
  4. 4
    PCNL with DJ Stenting: A double-J stent is placed to support healing and ensure urine drainage for 1–4 weeks.

The entire procedure typically takes 1–3 hours depending on stone complexity.

PCNL is designed for large stones where other methods like ESWL are unsuitable. It offers direct removal through a small incision for higher efficiency in complex cases.

How do I prepare for PCNL surgery?

Preparation includes blood tests, imaging, and stopping certain medications. Our team provides detailed instructions, including fasting before anaesthesia.
