Catheters, Urinary, Nephrostomy

Definition : Catheters used for insertion through the skin (i.e., percutaneously) into the renal pelvis to gain access to the upper urinary tract. These catheters consist of a large-bore (sizes from 14 to 24 Fr are typical), thin-walled tube, usually with a self-retained tip; some include expanding wings on their tips. Urinary nephrostomy catheters are used to perform drainage for relief of supravesical obstructions and are also used for a variety of procedures involving the upper urinary tract, such as dilation of strictures, removal of calculi, perfusion with chemolytic agents for dissolution of renal stones, and ureteral stenting.
