Nephrostomy

Surgical procedure that creates a long-term opening between the kidney and the skin

A nephrostomy or percutaneous nephrostomy is an artificial opening created between the kidney and the skin which allows for the urinary diversion directly from the upper part of the urinary system. It is an interventional radiology/surgical procedure in which the renal pelvis is punctured whilst using imaging as guidance. Images are obtained once an antegrade pyelogram, with a fine needle, has been performed. A nephrostomy tube may then be placed to allow drainage.
