What is percutaneous nephrostomy procedure?

Percutaneous nephrostomy is a medical procedure used to drain urine from the kidney when there is an obstruction in the urinary tract. It involves inserting a thin tube called a nephrostomy tube directly into the kidney through the skin.

Here's how the procedure typically works:

Preparation: The patient is usually given a local anesthetic to numb the area where the tube will be inserted. In some cases, sedation or general anesthesia may be used.

Imaging: Using ultrasound or fluoroscopy (real-time X-ray), the doctor guides a needle through the skin and into the kidney. This is done to ensure proper placement of the nephrostomy tube.

Insertion of the tube: Once the needle is in the correct position, a guide wire is passed through it and into the kidney. The needle is then removed, leaving the guide wire in place. The nephrostomy tube is then threaded over the guide wire and into the kidney.

Securing the tube: The tube is secured in place with sutures or adhesive dressing to prevent it from being dislodged.

Drainage: Urine will start to drain through the tube into a drainage bag or container. The tube allows the urine to bypass any blockage in the urinary tract, relieving pressure on the kidney.

Percutaneous nephrostomy is often used as a temporary measure to relieve symptoms while the underlying cause of the urinary obstruction is addressed. It can also be used to deliver medications directly into the kidney or to perform certain procedures, such as removing kidney stones.
