title: Percutaneous nephrolithotomy--the birth of a new technique.
abstract: Extraction of renal calculi via a percutaneous track was for the first time practised at the Karolinska Hospital in 1973. After very strict indications in the beginning because of fear of uncontrollable bleeding, the method was found to be safe and the technique was spread all over the world. Now being to a large extent replaced by extracorporeal shock wave lithotripsy (ESWL), percutaneous nephrolithotomy (PNL) has still many applications e.g. alone in obstructed kidneys or together with ESWL in staghorn calculi.
