Percutaneous Nephrostomy

ABSTRACT Percutaneous nephrostomy (PCN) is now established as a safe and effective early treatment for patients with urinary tract obstruction. In experienced hands, PCN is usually successful and is associated with low complication rates. This article discusses all aspects of PCN, including the indications and contraindications to PCN, patient preparation, the techniques employed for gaining access to the urinary tract, and placement of the PCN tube. In addition, we discuss the complications of PCN and possible ways of avoiding them, as well as the care of patients following PCN.
