Study Notes
Foley Catheter
- A flexible tube inserted through the urethra and into the bladder.
- Used for draining urine, particularly when urination is difficult or impossible.
- Two lumens: one for urine drainage, another connected to a balloon that inflates inside the bladder to secure positioning.
- Made from silicone or natural rubber.
- Sizes measured in French Units (F).
- Most common sizes: 10 F to 28 F, with 1 F equivalent to 0.33 mm diameter.
Uses of Foley Catheters
- Post-operative bladder drainage after surgery.
- Manage urinary incontinence.
- Monitor urine output in critically ill patients.
- Facilitate bladder irrigation for blood clots or infection.
Intermittent Catheter (Robinson Catheter)
- A flexible catheter used for short-term urine drainage.
- No balloon, making it suitable for temporary use.
- Can be coated or non-coated.
Coude Catheter
- Designed with a curved tip to navigate the curvature of the prostatic urethra.
Hematuria Catheter
- A Foley catheter used for hemostasis after surgical procedures or significant blood in the urine.
- Can be a two-way or three-way catheter.
Condom Catheters
- Used primarily for men, particularly those with dementia.
- Condom-like device placed over the penis, connected to a drainage bag.
- Requires daily replacement.
Intermittent Catheters (Short-term)
- Used when catheterization is only required occasionally.
- Removed after urine flow has stopped.
Suprapubic Catheter
- A catheter inserted directly into the bladder through a small incision in the abdomen.
- Used for long-term drainage.
- Equipped with three lumens: one for urine drainage, one for balloon inflation, and one for connecting to a pressure transducer for intra-abdominal pressure monitoring.
Drainage Bags
- Used to collect urine drained by catheters.
- Two types:
- Leg bags: small, worn during the day and easily emptied.
- Night drainage bags: larger, hold more urine and are usually hung or placed on the floor.
Equipment Needed for Catheterization
- Sterile gloves, drapes, cleansing solution, cotton swabs, forceps, sterile water, Foley catheter, syringe, lubricant.
Catheterization Procedure
- Gather equipment and explain the procedure to the patient.
- Position the patient supine with legs spread.
- Prepare the sterile field, apply sterile gloves, and check the balloon's patency.
- Lubricate the distal portion of the catheter.
- Apply sterile drapes.
- Cleanse the peri-urethral mucosa.
- Gently insert the catheter, identifying the urinary meatus.
- Inflate the balloon with sterile water.
- Gently pull the catheter until the balloon is snug against the bladder neck.
- Connect the catheter to the drainage system.
- Secure the catheter to the abdomen or thigh.
- Place the drainage bag below the level of the bladder.
- Evaluate catheter function and urine quality.
- Remove gloves, dispose of equipment, and wash hands.
- Document all relevant details.
Catheter Care
- Clean the area where the catheter exits the body and the catheter itself daily with soap and water.
- Clean after every bowel movement.
- Drink plenty of fluids.
- Wash hands before and after handling the drainage device.
- Keep the outlet valve clean.
- Empty the drainage bag at least every 8 hours or when full.
Causes of Urine Leakage
- Clogged or kinked catheter.
- Catheter size too small.
- Bladder spasms.
- Constipation.
- Wrong balloon size.
- Urinary tract infections.
Possible Complications
- Allergies or sensitivity to latex.
- Bladder stones.
- Blood infections (septicemia).
- Blood in the urine (hematuria).
- Kidney damage (usually only with long-term use).
- Urethral injury.
- Urinary tract or kidney infections.
When to Call a Healthcare Provider
- Bladder spasms that don't go away.
- Bleeding around the catheter.
- Fever or chills.
- Large amounts of urine leaking around the catheter.
- Skin sores around a suprapubic catheter.
- Stones or sediment in the urinary catheter or drainage bag.
- Swelling of the urethra around the catheter.
- Urine with a strong smell, thickness, or cloudiness.
- Very little or no urine draining from the catheter despite sufficient fluid intake.
Catheter Replacement
- If the catheter becomes clogged, painful, or infected, it needs to be replaced immediately.
