Percutaneous pigtail nephrostomy

Practicing urologists have become more familiar with the use of angiographic equipment and techniques and proficient in their application to percutaneous nephrostomy. The advantage of pigtail catheters for that purpose is noted. Modification of available vascular equipment applicable to percutaneous nephrostomy is discussed, and a new standardized kit for such purposes is described. A logical sequence of steps taken to ensure proper placement of the tube and adequate urinary drainage is considered.
