Ultra Sound (USG): PCN (Percutaneous Nephrostomy)

Specimen Required

NONE

Fasting Required

Purpose of the Test

Percutaneous nephrostomy (PCN) is a medical procedure that involves inserting a needle through the skin and into the kidney to drain urine that is blocked from flowing normally. This procedure is typically ordered by a doctor when there is an obstruction in the urinary system, such as a kidney stone, tumor, or scar tissue.

When this test is required

The procedure is requested by a doctor when a patient is experiencing symptoms such as severe pain, abdominal discomfort, blood in urine, or difficulty urinating, which may indicate a blockage in the urinary system. PCN may be recommended after other diagnostic tests, such as ultrasound or CT scan, have identified the location and cause of the blockage.

What the Test Detects

Percutaneous nephrostomy (PCN) is a medical procedure that is used to relieve a blockage in the urinary system by inserting a needle through the skin and into the kidney to drain urine. The procedure is guided by ultrasound imaging, which helps the doctor to accurately place the needle and drain the urine.

Preparation for the Test

After the procedure, patients may experience mild pain or discomfort at the site of the incision, but these symptoms can usually be managed with over-the-counter pain relievers. Patients should follow any instructions given by their healthcare provider regarding wound care and activity restrictions to ensure a smooth recovery.

Sample Requirements

No sample is required for this procedure. Patients should inform their healthcare provider about any allergies, medications, or medical conditions they have before undergoing PCN. They may also need to fast for a certain period of time before the procedure.

Additional Notes

After the procedure, patients may need to stay in the hospital for a short period of time to ensure that the drainage tube is functioning properly. They may also experience mild pain or discomfort at the site of the incision, but these symptoms can usually be managed with over-the-counter pain relievers. Patients should follow any instructions given by their healthcare provider regarding wound care and activity restrictions to ensure a smooth recovery. PCN is generally a safe procedure, but as with any medical procedure, there are potential risks and complications, including bleeding, infection, and damage to nearby organs. Patients should discuss the risks and benefits of the procedure with their healthcare provider before undergoing PCN.
