b. Retention/Indwelling Catheter. This type of catheter is placed into the
bladder and secured there for a period of time. It is used following surgery, bladder
injury, or in bladder infections. It may also be used for an incontinent or nonresponsive
It provides continuous temporary or permanent drainage of urine.
It is used for gradual decompression of an over distended bladder.
It is used for intermittent drainage and irrigation.
(4) The most commonly used indwelling catheter is the Foley catheter. A
drainage tube and collection device are connected to the catheter. It has a balloon at
the distal end, which is inflated with sterile water or saline to prevent the catheter from
slipping out of the bladder. It is multi-lumened (having several passages within the
catheter). One lumen provides a passage for fluid to inflate the balloon. This passage
may be self-sealing or may require a clamp. The second lumen is the passage through
which the urine drains. Some indwelling catheters have a third lumen for instilling
c. Supra Pubic Catheter. This type of catheter is inserted into the bladder
through a small incision above the pubic area. It is used for continuous drainage.
PREPARING FOR CATHETERIZATION
A catheter should be used only when absolutely necessary and the
catheterization procedure itself should be done only by trained personnel under sterile
conditions. Infection is a major risk of urinary catheterization.
a. Gather All Equipment.
(1) Disposable indwelling catheter kit. The kit contains the required
equipment needed for catheterization and is packaged to ensure that the equipment is
sterile. The kit includes the catheter, a drape, a receptacle to receive urine, materials to
clean the area of insertion, a lubricant, a specimen container, and sterile gloves.
Flashlight or lamp.
Urine collection bag.
Velcro leg strap or anchoring tape.
Waterproof pad or Chux.
