What Is Intermittent Catheterization?
Intermittent catheterization (IC) is the process of inserting a thin, flexible tube (catheter) into the bladder through the urethra to drain urine, then removing it. Unlike indwelling (Foley) catheters that stay in place, intermittent catheters are used for a few minutes at a time, several times per day.
IC is the gold standard for bladder management recommended by urologists worldwide. It’s safer than indwelling catheters because the bladder is emptied and the catheter removed, reducing infection risk.
Who Needs Intermittent Catheterization?
- Spinal cord injury — neurogenic bladder, cannot void naturally
- Multiple sclerosis — bladder dysfunction
- Spina bifida — lifelong bladder management
- Post-surgical urinary retention — temporary inability to urinate
- Enlarged prostate (BPH) — incomplete bladder emptying
- Stroke — neurological bladder impairment
- Diabetes — diabetic cystopathy affecting bladder nerves
Types of Intermittent Catheters
Uncoated (Standard)
Basic PVC catheters that require separate lubrication (water-based gel). Most affordable option. Requires a clean surface to apply lubricant. Good for home use.
Hydrophilic-Coated
Pre-coated with a polymer that becomes slippery when activated with water. No separate lubricant needed. Smoother insertion, less friction, lower risk of urethral trauma. Brands: Coloplast SpeediCath, Wellspect LoFric.
Pre-Lubricated
Come with lubricant already applied in the packaging. Ready to use immediately — no water activation required. Most convenient option. Brands: Hollister Apogee Plus, Bard Touchless.
Closed System
The catheter comes inside a self-contained collection bag. Designed for on-the-go use — no need for a separate urine container. Ideal for catheterizing away from home. Brands: Hollister Advance Plus, Coloplast SpeediCath Compact.
Choosing the Right Size
Catheter size is measured in French (Fr) units. One French = 0.33mm diameter.
| User | Typical Size |
|---|---|
| Adult women | 10-14 Fr |
| Adult men | 12-16 Fr |
| Children | 6-10 Fr |
Your healthcare provider will recommend the right size. Using the smallest effective size minimizes discomfort while ensuring proper drainage.
Length
- Female catheters: 6-8 inches (shorter urethra)
- Male catheters: 14-16 inches (longer urethra)
- Pediatric: 6-10 inches depending on age
How Often to Catheterize
Most people catheterize 4-6 times per day, roughly every 4-6 hours. Your schedule depends on:
- Fluid intake
- Bladder capacity (usually 400-500ml)
- Your healthcare provider’s recommendation
Important: Don’t let your bladder overfill. Volumes over 500ml increase UTI risk and can damage the bladder.
Hygiene Tips
- Wash hands thoroughly before and after catheterization
- Clean the urethral area with a wipe or warm water
- Use a new catheter each time (single-use is recommended)
- Stay hydrated — drink 6-8 glasses of water daily to flush bacteria
- Consider cranberry supplements to support urinary health
Common Concerns
Does it hurt?
Most people experience mild discomfort initially, which improves with practice. Hydrophilic and pre-lubricated catheters significantly reduce friction and discomfort. Many users report that it becomes routine within a week.
Will I get infections?
IC has the lowest UTI rate of all catheterization methods. Using proper hygiene, single-use catheters, and adequate hydration minimizes risk.
Can I travel?
Absolutely. Compact and closed-system catheters are designed for travel. Pack more than you think you’ll need, and carry supplies in your carry-on luggage when flying.
