Percutaneous nephrostomy

Percutaneous Nephrostomy is a medical procedure that involves the insertion of a small, flexible rubber tube (or catheter) through the skin into the kidney to drain the urine.

Procedure

The procedure is usually performed by a radiologist under ultrasound or CT scan guidance. The patient is given a local anesthetic to numb the area where the catheter will be inserted. The catheter is then inserted through the skin and into the kidney where it drains the urine into a bag outside the body.

Indications

Percutaneous nephrostomy is often used to treat hydronephrosis, a condition where the kidney swells due to a blockage in the flow of urine. This can be caused by a variety of conditions, including kidney stones, tumors, or blood clots. It can also be used to treat infection in the kidney or to deliver medication directly to the kidney.

Risks and Complications

Like any medical procedure, percutaneous nephrostomy carries some risks. These can include infection, bleeding, and injury to the kidney or surrounding organs. There is also a risk that the catheter could become blocked or dislodged.

Aftercare

After the procedure, patients are usually monitored in the hospital for a short period of time. They are then sent home with instructions on how to care for the catheter and bag. Regular follow-up appointments are necessary to ensure that the catheter is functioning properly and that the underlying condition is being treated effectively.
