Urinary catheterization
Urinary catheterization is a medical procedure that involves the insertion of a tube into a patient's bladder. This tube, known as a urinary catheter, is used to drain urine from the bladder when the patient is unable to do so naturally.
Indications[edit | edit source]
Urinary catheterization is typically performed when a patient is unable to urinate on their own due to a medical condition or surgical procedure. Some common indications for urinary catheterization include:
- Urinary retention: This is a condition where the bladder is unable to empty completely. It can be caused by a variety of conditions, including prostate enlargement, nerve damage, and certain medications.
- Urinary incontinence: This is a condition where a person is unable to control their bladder. It can be caused by a variety of conditions, including nerve damage, pregnancy, and aging.
- Surgery: During certain surgical procedures, a urinary catheter may be inserted to monitor urine output and prevent bladder distention.
- Critical illness: In critically ill patients, a urinary catheter may be inserted to monitor urine output and fluid balance.
Procedure[edit | edit source]
The procedure for urinary catheterization varies depending on the type of catheter used. The most common types of urinary catheters are indwelling catheters, intermittent catheters, and external catheters.
- Indwelling catheters: Also known as a Foley catheter, this type of catheter is inserted into the bladder through the urethra and left in place for a prolonged period.
- Intermittent catheters: This type of catheter is inserted into the bladder through the urethra and removed after the bladder is emptied. It is typically used for patients who need to self-catheterize.
- External catheters: Also known as a condom catheter, this type of catheter is placed over the penis and collects urine into a drainage bag.
Risks and Complications[edit | edit source]
Like any medical procedure, urinary catheterization carries some risks and potential complications. These may include:
- Urinary tract infection (UTI): This is the most common complication of urinary catheterization. It can occur when bacteria enter the urinary tract through the catheter.
- Bladder damage: This can occur if the catheter is inserted incorrectly or if the bladder is overdistended.
- Urethral injury: This can occur if the catheter is inserted incorrectly or forcefully.
