PCNL Surgery

PCNL Surgery

What is PCNL Surgery?

PCNL (Percutaneous Nephrolithotomy) is an advanced surgical procedure used to remove large kidney stones, usually those larger than 2 cm or stones that cannot be treated with other methods such as shock wave therapy or ureteroscopy.

In this procedure, the surgeon makes a small incision in the back to directly access the kidney and remove the stone using specialized instruments. PCNL is considered one of the most effective treatments for large, complex, or multiple kidney stones.

Large Stone Management

Large kidney stones can block the urinary tract and cause severe pain, infection, or kidney damage if not treated properly. When stones grow larger than 2 cm or form complex shapes (such as staghorn stones), minimally invasive procedures like PCNL are usually recommended.

PCNL allows doctors to remove large stones completely in a single procedure, making it a highly effective option for managing complex kidney stones.

Procedure Steps:

PCNL surgery is performed under general anesthesia and usually involves the following steps:

  1. Patient Preparation: The patient is given anesthesia so they remain comfortable and pain-free during the procedure.

  2. Small Incision in the Back: A small cut (about 1 cm) is made in the patient’s back to create a pathway to the kidney.

  3. Access to the Kidney: A special tube is inserted through the incision to reach the kidney where the stone is located.

  4. Stone Visualization: A tiny camera (nephroscope) is used to locate the kidney stone inside the kidney.

  5. Stone Fragmentation: The stone is broken into smaller pieces using ultrasonic, pneumatic, or laser energy.

  6. Stone Removal: The fragments are removed through the tube to clear the kidney.

  7. Drainage Tube Placement: In some cases, a temporary tube may be placed to help drain urine from the kidney during recovery.

Hospital Stay

Patients undergoing PCNL surgery typically require a short hospital stay.

  • Hospital stay is usually 2–3 days depending on recovery.

  • Most patients can return to light activities within 1–2 weeks.

  • Doctors may recommend drinking plenty of water and following dietary precautions to prevent future stones.

Regular follow-up and imaging tests may be advised to ensure the kidney is completely clear of stones.
