Terminology

Catheter Types

Catheters used for colonic insufflation. Note the different sizes of the balloons: 5-mL balloon of the Foley catheter (A), 30-mL balloon of the rectal catheter of the CO2 pump (B), and 100-mL balloon of the barium enema tip catheter (C). The larger size of the barium enema tip catheter can be useful in patients who have difficulty retaining insufflated air.

Angiography Catheter

Foley Catheter: The syringe is attached to an adapter which is attached to a thin tube within the catheter. Fluid or air is injected into this tube which terminates in a thin walled balloon. The balloon capacity is printed on the white plastic adapter (a) (usually 3 to 5 ml). The balloon is inflated when the catheter is in the lumen of the bladder (b). The intent is to retain the catheter in the bladder. The balloon is deflated prior to catheter removal by aspirating back the fluid or air. The adaptor contains a valve which prevents loss of fluid or air

Urinary Catheters• Urinary catheters are available in

various types, sizes and materials. The most common type is the Foley catheter, which may have 2-3 lumens. Each lumen is used for different functions usually inflation, drainage and irrigation.

• Catheters are sized by the diameter of the outer circumference using the French (Fr) metric scale (range from 6Fr- 24Fr).

• Never use short (female length) catheters in adult males which resulted in trauma to the urethra.
