Percutaneous Nephrolithotomy (PCNL) at Urology Clinic DRHC Dubai

Percutaneous nephrolithotomy (PCNL) is a minimally invasive procedure used to remove large or complex kidney stones that cannot be treated with other methods such as shockwave lithotripsy or ureteroscopy. Here is a comprehensive overview of PCNL:


  • Large kidney stones: PCNL is particularly effective for stones larger than 2 cm in diameter.
  • Complex kidney stones: Stones that are hard, irregularly shaped, or located in a difficult-to-access part of the kidney.
  • Stones causing symptoms: Stones that are causing pain, infection, or kidney damage.

How Percutaneous Nephrolithotomy (PCNL) done?

Percutaneous nephrolithotomy (PCNL) is a minimally invasive surgical procedure used to remove large or complex kidney stones. Here is an overview of how PCNL is typically performed:

Pre-operative Preparation:

  • Anesthesia: The patient is usually given general anesthesia, which means they are asleep and feel no pain during the procedure.
  • Imaging: Before the procedure, imaging tests such as CT scans or X-rays are done to locate the kidney stones and plan the surgery.


  1. Preparation: The patient is usually given anesthesia, either general or local, to ensure comfort during the procedure.
  2. Dilation: A series of dilators are passed over the needle to create a tract through the skin and into the kidney.
  3. Insertion of ureteroscope: The ureteroscope is inserted into the urethra and advanced through the bladder into the ureter and kidney.
  4. Visualization: The camera at the tip of the ureteroscope allows the urologist to visualize the inside of the urinary tract on a monitor.
  5. Stone removal: The stone is broken up using a laser, ultrasonic or pneumatic probe, and the fragments are removed through the nephroscope.
  6. Placement of a nephrostomy tube: A tube may be left in place to drain the kidney and facilitate healing of the tract.


  • Short hospital stay: URS is usually performed as a day surgery procedure, and most patients can go home the same day.
  • Recovery time: Most patients can return to normal activities within a few days after the procedure, although strenuous activities may need to be avoided for a short period.
  • Follow-up: A follow-up appointment may be scheduled to ensure that the urinary tract is healing properly.

Risks and Complications:

  • Bleeding: Some degree of bleeding is common after URS, but it is usually minor and resolves on its own.
  • Infection: There is a small risk of developing a urinary tract infection after URS.
  • Perforation: In rare cases, the ureteroscope can cause a perforation (hole) in the ureter or kidney.


  • Minimally invasive: URS is less invasive than traditional surgery, resulting in less pain and a faster recovery time.
  • High success rate: URS is highly effective for treating kidney and ureteral stones, with a high success rate of stone clearance.
