Where is a catheter inserted?

Answer 1

in the urethra

Answer 2

A catheter goes into the bladder through the urethra on the outside of the body. It is held in place by a bubble filled with water that is blown up after it is inserted. When inserting a catheter, you can confirm that it is in the correct placement and in the bladder when you see "urine flashback" (urine starts draining into the tubing).

Answer 3

One or more catheters is inserted through a peripheral blood vessel in the arm (antecubital artery or vein) or leg (femoral artery or vein) with x-ray guidance.
