Urinary Catheterization Purposes | Catheter Types and Uses

Definition of Urinary Catheterization:

Urinary catheterization is the insertion of a special catheter into the urinary bladder, using aseptic technique, for the purposes of evacuating or instilling fluids. In urinary catheterization a latex, polyurethane, or silicone tube known as a urinary catheter is inserted into a patient’s bladder via the urethra.

Purposes of Urinary Catheterization:

The main purposes of cauterizations have pointed out in the below:

1. To drain the bladder before, during, or after surgery.
2. For the relief of bladder distention.
3. For the control of incontinence.
4. When an accurate measurement of urine output is necessary.
5. For the orthopedic patient, those with casts, traction, pelvic fractures and the like.
6. For the paralyzed or comatose patient.

Types of Catheterization:

It includes-

• Urethral catheterization
• Cardiac catheterization,
• Arterial catheterization,
• Ureteric catheterization,
• Suprapubic catheterization.

Types of Catheters:

There are four types of catheters such as-

• Rubber catheters.
• Polythene catheters.
• Hard rubber catheters
• Metal catheters.

Types of Urinary Catheter:

There are three main types of catheters:

1. Indwelling Catheters (Urethral or Suprapubic Catheters):

An indwelling catheter is a catheter that resides in the bladder. It may also be known as a Foley catheter. This type can be useful for both short and long periods of time. A doctor usually inserts an indwelling catheter into the bladder through the urethra.

2. External Catheters (Condom Catheters):

A condom catheter is a catheter placed outside the body. This type of catheter is typically necessary for men who don’t have urinary retention problems but have serious functional or mental disabilities, such as dementia. A device that looks like a condom covers the penis head. A tube leads from the condom device to a drainage bag.

3. Short-Term (Intermittent) Catheters:

Sometimes a patient only needs a catheter for a short period of time after surgery, after the bladder empties, it’s necessary to remove the short-term catheter.
