Types:
1) Straight Catheter - Also called a red rubber or straight cath have a single lumen without a balloon.
They are used for draining the bladder in the instance of acute retention or for obtaining a urine speciman and then removed.
2) Indwelling Catheter - Also called a Foley or Retention cath come in two differnt type both with an inflation
balloon near the tip.
a) Two Way - has two lumens one to drain bladder content the other to inflate balloon
b) Three Way - has the two lumens as described above as well as a third to allow for continuous or intermittent
bladder irrigations.
Procedure:
Gather equipment: This varies a lot in what is required by facility policy, whether you are inserting
for the first time and why the procedure was ordered.
Explain procedure to patient
- Assist patient into supine position with legs spread and feet together
- Open catheterization kit and catheter
- Prepare sterile field, apply sterile gloves
- Check balloon for patency.
- Generously coat the distal portion (2-5 cm) of the catheter with lubricant
- Apply sterile drape
- If female, separate labia using non-dominant hand. If male, hold the penis with the non-dominant hand. Maintain hand position
until preparing to inflate balloon.
- Using dominant hand to handle forceps, cleanse peri-urethral mucosa with cleansing solution. Cleanse anterior to posterior,
inner to outer, one swipe per swab, discard swab away from sterile field.
- Pick up catheter with gloved (and still sterile) dominant hand. Hold end of catheter loosely coiled in palm of dominant
hand.
- In the male, lift the penis to a position perpendicular to patient's body and apply light upward traction (with non-dominant
hand)
- Identify the urinary meatus and gently insert until 1 to 2 inches beyond where urine is noted
- Inflate balloon, using correct amount of sterile liquid (usually 10 cc but check actual balloon size)
- Gently pull catheter until inflation balloon is snug against bladder neck
- Connect catheter to drainage system
- Secure catheter to abdomen or thigh, without tension on tubing
- Place drainage bag below level of bladder
- Evaluate catheter function and amount, color, odor, and quality of urine
- Remove gloves, dispose of equipment appropriately, wash hands
- Document size of catheter inserted, amount of water in balloon, patient's response to procedure, and assessment of urine
