Foley’s Catheterization & Removal - ARDEN HOME HEALTH CARE

Foley Catheterization

A Foley catheter is a type of indwelling catheter that is inserted into the bladder to facilitate the drainage of urine. It has a balloon at the tip that can be inflated once in the bladder to keep it in place. This method allows for continuous drainage and is particularly useful for patients who are unable to void naturally due to various medical conditions.

Indications

Urinary Retention: Conditions such as bladder outlet obstruction or neurological disorders can prevent normal urination. A Foley catheter allows for continuous drainage.
Surgical Procedures: In many surgical scenarios, especially those involving the pelvic region or the urinary tract, keeping the bladder empty reduces the risk of injury during surgery and allows for easier monitoring of urine output.
Urinary Incontinence: In some cases of severe urinary incontinence, especially when other treatments have failed, a Foley catheter may be used to manage symptoms.
Monitoring Urine Output: In critically ill patients, precise measurement of urine output is vital for assessing kidney function and fluid status. A Foley catheter provides accurate data for medical teams.
Diagnostic Procedures:Foley catheters can be utilized during diagnostic tests, such as urodynamics or imaging studies, to visualize the bladder.

Contraindications

Urethral Injury: If there is trauma or injury to the urethra, attempting to insert a catheter could worsen the injury or lead to complications.
Severe Urethral Strictures: In cases where the urethra is significantly narrowed, catheterization may not be possible and could cause further damage.
Recent Pelvic Surgery: After certain surgeries, especially those involving the bladder or urethra, catheterization may pose a risk of complications.
Allergic Reactions: Patients with known allergies to latex or materials used in the catheter should avoid Foley catheters made from those materials.

Risk Factors

Infection: The most common complication associated with Foley catheters is urinary tract infections (UTIs). Bacteria can enter the urinary tract through the catheter, leading to infection.
Obstruction: Catheters can become blocked due to sediment or mucus, which can lead to bladder distension and discomfort.
Bladder Spasms: The presence of the catheter can irritate the bladder wall, causing involuntary contractions or spasms, leading to discomfort.
Trauma: Improper insertion or removal can result in trauma to the urethra or bladder, which can have lasting effects.
Prolonged Use: Extended use of a Foley catheter can lead to chronic issues such as bladder atony (loss of bladder muscle tone) and increased risk of infections.

Best Practices

Sterile Technique: Always use sterile techniques during insertion and maintenance to minimize the risk of infection.
Regular Monitoring: Keep track of urine output and the catheter’s condition. Look for signs of infection, blockage, or other complications.
Scheduled Removal: Catheters should be removed as soon as they are no longer necessary to reduce risks associated with prolonged use.
