Percutaneous Nephrolithotomy for Kidney Stones

Overview

Kidney stones are hard deposits made of minerals and salts that form in the kidneys and can cause pain, nausea, and difficulty urinating as they pass through the urinary tract.

Percutaneous nephrolithotomy (PCNL) is a surgical procedure used to treat kidney stones larger than 2 cm. It involves the following steps:

Pre-procedure preparation:

• Your doctor will provide specific instructions, which may include fasting before the procedure.
• You may need to stop certain medications that can increase the risk of bleeding.
• Blood tests and imaging studies may be done to assess your overall health and determine the size and location of the stones.

Step-by-step description of the procedure:

• You will be given anesthesia to ensure you are comfortable during the procedure.
• The surgeon will make a small incision in your back and insert a needle to access the kidney.
• Using fluoroscopic imaging, the surgeon will guide a nephroscope (a thin tube with a camera) into the kidney.
• The stones will be broken into smaller pieces using specialized tools and removed through the nephroscope.
• If necessary, a temporary tube called a nephrostomy tube may be left in place to drain urine from the kidney.

Recovery and follow-up instructions:

• After the procedure, you will be monitored in a recovery area until you wake up from anesthesia.
• Pain medication may be prescribed to manage any discomfort.
• You may need to stay in the hospital for a few days, depending on your specific situation.
• Follow your doctor's instructions regarding diet, activity level, and medication use during recovery.
• A follow-up appointment will be scheduled to monitor your progress and remove any remaining tubes or stents.

Potential complications and precautions:

• Complications can include bleeding, infection, damage to surrounding organs or blood vessels, and residual stone fragments.
• It is important to follow post-procedure instructions carefully to minimize these risks.
• Contact your doctor if you experience severe pain, fever, persistent bleeding, or any other concerning symptoms.

Remember, this information is general. Your doctor will provide personalized instructions based on your specific condition and needs.
