n.
drainage of urine from the kidney by a tube (catheter) passing through the kidney via the skin surface. This is commonly used as a temporary procedure after operations on the kidney. Long-term urine drainage by nephrostomy may be complicated by the attendant problems of infection and obstruction of the catheter by debris. Nephrostomy is also performed to enable the passage of a nephroscope.
