| nephrostomy, percutaneous | The insertion of a catheter through the skin and body wall into the kidney pelvis, mainly to provide urine drainage where the ureter is not functional. It is used also to remove or dissolve renal calculi and to diagnose ureteral obstruction. (12 Dec 1998) |
| diskectomy, percutaneous | Percutaneous excision of a herniated or displaced intervertebral disk by posterolateral approach, always remaining outside the spinal canal. Percutaneous nucleotomy was first described by hijikata in japan in 1975. In 1985 onik introduced automated percutaneous nucleotomy which consists in percutaneous aspiration of the nucleus pulposus. It is carried out under local anaesthesia, thus reducing the surgical insult and requiring brief hospitalization, often performed on an outpatient basis. It appears to be a well-tolerated alternative to surgical diskectomy and chymopapain nucleolysis. (12 Dec 1998) |
| transluminal percutaneous coronary angioplasty | <cardiology, procedure> Dilatation of an occluded coronary artery (or arteries) by means of a balloon catheter to restore myocardial blood supply. (07 Mar 2000) |

| regular insulin injection | A preparation that may contain 20, 40, 80, 100, or 500 USP insulin units per ml, although the trend is toward standardizing all insulin preparations at 100 units per ml; it is administered subcutaneously, occasionally intravenously, and has a rapid onset of action, has a brief duration (5 to 7 hours), and is compatible for mixing with long-acting insulin preparations; used in the treatment of diabetic acidosis and insulin coma. Synonym: regular insulin injection. (05 Mar 2000) |
