PCNL

Common questions answered by Dr. Freddy Urroz, Urologist in Belize

Percutaneous nephrolithotomy, or PCNL, is a specialized procedure designed to treat large kidney stones that cannot be passed naturally or broken up with other methods like shockwave lithotripsy (SWL). As a urologist in Belize, I frequently perform PCNL for patients with complex or large stones that require more advanced treatment. In this post, I’ll explain the PCNL procedure, its benefits, and how it can effectively resolve kidney stones.

What Is PCNL?

PCNL, or Percutaneous Nephrolithotomy, is a minimally invasive surgical procedure used to remove kidney stones that are too large to be treated by other non-invasive methods. The term “percutaneous” means “through the skin,” and nephrolithotomy refers to removing kidney stones. This technique allows me to access the kidney directly and remove the stones without needing a large incision.

PCNL is especially recommended for stones that are:

  • Larger than 2 cm
  • Causing severe pain or urinary obstruction
  • Staghorn stones, which are large stones that occupy the renal pelvis and branching structures in the kidney
  • Resistant to other treatments like ureteroscopy or shockwave lithotripsy

Who Needs PCNL?

PCNL is typically recommended for patients with larger or more complex kidney stones. If other treatments such as medication, dietary changes, or less invasive methods like extracorporeal shock wave lithotripsy (ESWL) have failed, PCNL may be the best solution. Patients with the following conditions are likely candidates:

  • Large kidney stones: Stones larger than 2 cm are unlikely to pass on their own and may require surgical intervention.
  • Staghorn calculi: These are large, branching stones that can fill much of the kidney, causing significant pain and potential damage to the kidney.
  • Stones resistant to other treatments: Some stones may not break up with shockwave lithotripsy, especially if they are made of harder materials like cystine or calcium oxalate.

How Is PCNL Performed?

PCNL is performed under general anesthesia and involves the use of a small tube inserted through the skin into the kidney to remove the stones. Here’s a step-by-step breakdown of how the procedure works:

  1. Preparation and Imaging:
    Before surgery, you will undergo imaging tests such as an ultrasound, X-ray, or CT scan to determine the exact location, size, and type of kidney stone.

  2. Access to the Kidney:
    During the procedure, I will make a small incision in your back, usually about 1 cm, and guide a thin tube (nephroscope) through the skin and into the kidney. The tube provides a direct channel to the kidney.

  3. Stone Removal:
    Using the nephroscope, I locate the kidney stones and either break them up with specialized tools or remove them entirely, depending on their size and composition. For larger stones, I may use ultrasound or laser energy to fragment them into smaller, more manageable pieces.

  4. Post-Procedure Care:
    After the stones are removed, a temporary drainage tube may be placed in the kidney to allow it to heal and drain urine. The procedure typically lasts 2-4 hours, depending on the size and number of stones.

What Are the Benefits of PCNL?

PCNL is one of the most effective methods for treating large and complex kidney stones. Some of the key benefits include:

  • Minimally invasive: PCNL requires only a small incision, reducing recovery time and the risk of complications compared to traditional open surgery.
  • High success rate: PCNL has a high success rate for removing large kidney stones, especially those that cannot be treated with other methods.
  • Fewer complications: Because the procedure allows direct access to the kidney, it minimizes damage to surrounding tissues and organs.
  • Quick recovery: Most patients are able to resume normal activities within a week or two following PCNL, and hospital stays are typically short—usually 1 to 2 days.

What Should I Expect After PCNL?

Following the PCNL procedure, you will be monitored in the hospital for 1-2 days to ensure proper recovery. You may experience some mild discomfort or pain at the incision site, but this can be managed with pain medication. Here’s what to expect during recovery:

  • Hospital Stay: You will likely stay in the hospital for 1-2 days, during which I will monitor your kidney function and ensure that your body is recovering properly.
  • Drainage Tube: A nephrostomy tube may be left in place temporarily to allow the kidney to drain and heal. This tube will be removed after a few days once the kidney is functioning normally.
  • Follow-up Imaging: You will need a follow-up X-ray or CT scan to ensure all stones have been removed and there are no remaining fragments.
  • Activity Restrictions: It’s important to avoid strenuous activity or heavy lifting for 2-4 weeks after the procedure to allow the incision site and kidney to heal properly.
  • Hydration: Staying well-hydrated is crucial after surgery to help flush out any remaining stone fragments and prevent future stone formation.

What Are the Risks of PCNL?

While PCNL is generally safe, as with any surgery, there are some potential risks. These include:

  • Bleeding: Minor bleeding is common during PCNL, but in rare cases, more significant bleeding may require additional treatment.
  • Infection: There is a risk of infection, which is managed with antibiotics during and after the procedure.
  • Damage to surrounding structures: Although rare, there is a possibility of injury to nearby organs or blood vessels.
  • Residual stones: In some cases, small stone fragments may remain after the procedure, which may require further treatment.

I will discuss all potential risks with you before the procedure to ensure you are fully informed and prepared.

Why Choose PCNL?

PCNL is the gold standard for treating large or complex kidney stones. If you’ve been experiencing recurring pain or discomfort due to kidney stones, or if other treatments haven’t worked, PCNL could provide a long-term solution.

At my clinic in Belize, I offer PCNL as part of my comprehensive kidney stone treatment services. Using the latest technology and minimally invasive techniques, I ensure that my patients receive the highest level of care with minimal recovery time.

Final Thoughts

Percutaneous nephrolithotomy is an effective and minimally invasive option for removing large kidney stones that can’t be treated with other methods. If you are struggling with kidney stones, I encourage you to schedule a consultation with me to discuss whether PCNL is the right option for you.
