Intermittent Catheters: Complete Beginner's Guide 2026

If your doctor has just prescribed intermittent catheterization, you may be feeling overwhelmed. The idea of inserting a catheter multiple times a day can sound daunting — even alarming. But here's what millions of people who self-catheterize already know: once you've learned the technique and done it a handful of times, intermittent catheterization becomes a straightforward part of the daily routine, takes only a few minutes, and provides dramatically better bladder management than many alternatives.

This guide explains what intermittent catheterization is, why doctors prescribe it, the different types of catheters available in 2026, and what to expect when you're starting out. Browse our full range of Catheter Supplies at AllCare Store.

What Is Intermittent Catheterization?

Intermittent catheterization (IC), also called clean intermittent catheterization (CIC) or intermittent self-catheterization (ISC), is the process of draining the bladder by temporarily passing a thin, flexible tube (catheter) through the urethra into the bladder, allowing urine to flow out, then removing the catheter. This is done multiple times throughout the day — typically 4–6 times, depending on the individual's fluid intake and bladder capacity.

Unlike an indwelling (Foley) catheter, which stays in place 24 hours a day, an intermittent catheter is inserted only for the duration of drainage and then removed. This approach has important advantages: it dramatically reduces urinary tract infection risk compared to indwelling catheters, preserves bladder tone and capacity, allows more normal social functioning, and is generally more comfortable for long-term bladder management.

Who Uses Intermittent Catheters?

Intermittent catheterization is prescribed for anyone whose bladder does not empty adequately on its own. Common conditions requiring IC include:

• Spinal cord injury: One of the most common reasons for IC; the nerve signals that control bladder emptying are disrupted
• Multiple sclerosis (MS): MS frequently affects bladder control and emptying
• Spina bifida: Many people with spina bifida use IC from childhood
• Neurogenic bladder from stroke, Parkinson's disease, or other neurological conditions
• Urinary retention: Bladder that does not empty fully due to obstruction or weak bladder muscle
• Post-surgical bladder dysfunction: After prostate surgery, pelvic surgery, or other procedures that temporarily or permanently affect bladder function
• Urethral stricture or other anatomical conditions that impede urine flow

Types of Intermittent Catheters

The catheter market has expanded significantly over the past decade, and there are now multiple catheter types designed for different needs, preferences, and lifestyles. Understanding the options helps you and your healthcare provider choose the right catheter.

Standard (Uncoated) Intermittent Catheters

The original intermittent catheter design: a plain PVC or latex-free tube with no coating. These require lubrication with a separate lubricant before insertion. They are the most widely available and typically the least expensive option. Many people use these successfully for years. The main consideration is the additional step of applying lubricant, which can be inconvenient when away from home.

Pre-Lubricated (Hydrophilic) Catheters

Hydrophilic catheters have a coating that absorbs water to create a slippery, lubricated surface. When activated with water (either from a separate water sachet in the package or from a built-in water reservoir), the entire outer surface becomes extremely slick — significantly reducing friction during insertion and withdrawal compared to uncoated catheters. Research consistently shows that hydrophilic catheters are associated with less urethral trauma and lower rates of urinary tract infection over long-term use. They are more expensive per unit than uncoated catheters but are preferred by many users for comfort and convenience.

Gel-Pre-Lubricated Catheters

Some catheters come with a sterile lubricating gel already applied in the packaging. These don't require water activation — just open the package and the catheter is ready to use. These offer maximum convenience for people who catheterize outside the home frequently.

Compact and Travel Catheters

Standard intermittent catheters are typically 14–16 inches long. Compact catheters fold, coil, or are otherwise shortened for discreet carry in a pocket, purse, or small pouch. These are particularly valued by active individuals and those who travel frequently. Compact designs are available in both coated and uncoated versions.

Closed-System Catheters

A closed-system catheter is pre-packaged inside a sterile collection bag. The catheter is inserted through an introducer tip (which bypasses the non-sterile first portion of the urethra) into the bladder, and urine drains directly into the bag — the catheter never contacts external surfaces. This design offers the highest level of sterility and is recommended for people who are highly susceptible to UTIs or who catheterize in environments where maintaining sterility is difficult. They are also appropriate for individuals who cannot adequately clean their hands before catheterization.

Female vs. Male Catheters

Catheter length differs by anatomy. Female catheters are typically 6–8 inches long (the female urethra is short). Male catheters are 14–16 inches long to reach the bladder through the longer male urethra. Some women prefer standard-length catheters for easier handling; others prefer the compact female length for discretion. Your healthcare provider will specify the appropriate length for your anatomy.

Understanding French Size (Catheter Diameter)

Catheters are sized in French (Fr) units — a measure of outer circumference. One French equals approximately 0.33 mm in diameter, so a 14 Fr catheter is about 4.7 mm in outer diameter. Larger French sizes drain more quickly but may be more uncomfortable to insert, especially initially.

French Size	Diameter	Typical Use
8–10 Fr	2.7–3.3 mm	Pediatric; some females with sensitive urethras
12 Fr	4 mm	Women; those new to catheterization
14 Fr	4.7 mm	Most common adult size; men and women
16 Fr	5.3 mm	Men; larger urethra or faster drainage needed
18 Fr	6 mm	Larger urethra; specific clinical situations

Your prescribing physician will specify the appropriate French size. If you find the prescribed size too uncomfortable or if drainage is insufficient, discuss changing sizes with your provider.

How to Perform Clean Intermittent Catheterization (Overview)

Important: The following is a general overview. Your urology nurse or continence specialist will provide personalized, step-by-step instruction with hands-on training. The first several catheterizations should be learned with supervision.

Supplies You'll Need

• Sterile catheter (appropriate type, size, and length)
• Lubricant (if using uncoated catheter)
• Soap and water for hand washing (or hand sanitizer if soap unavailable)
• Clean towel or disposable wipes for genital cleaning
• Collection container or toilet
• Good lighting
• Mirror (for women learning self-catheterization)

General Procedure

1. Wash hands thoroughly with soap and water for at least 20 seconds. This is the most important infection prevention step.

2. Prepare the catheter. Open the package using sterile technique. If using an uncoated catheter, apply lubricant to the insertion end. If using a hydrophilic catheter, activate the coating with water per manufacturer instructions (typically a brief soak or squeeze of the water sachet).

3. Clean the urethral opening. For women: use a downward stroke with a clean wipe, front to back, to clean the labia and urethral opening. For men: clean the glans and urethral meatus with a wipe. Use a new wipe for each stroke.

4. Locate the urethral opening. For women, this can be the most challenging part of self-catheterization — especially initially. A mirror and good lighting are essential. The urethra is between the clitoris and vaginal opening. With practice, most women can locate it reliably by feel. For men, the urethra is at the tip of the penis.

5. Insert the catheter gently. Holding the catheter with clean hands (typically at the non-insertion end, or through the packaging sleeve for closed-system catheters), insert the tip into the urethral opening with a slow, steady, gentle motion. Do not force. For men, hold the penis at a slight upward angle during insertion. Resistance may be felt at the prostate — a slow, steady gentle push usually allows passage. Insert until urine flows.

6. Drain the bladder completely. Allow urine to flow into the toilet or collection container until flow stops completely. You may need to rotate the catheter slightly or adjust position if flow slows before the bladder is empty. When flow stops, slowly withdraw the catheter about 1 inch to check if any urine was pooled at an angle — if flow resumes, wait for it to stop again before continuing withdrawal.

7. Remove the catheter. Once urine flow has completely stopped, slowly and steadily withdraw the catheter. Do not pull sharply.

8. Dispose of or clean the catheter. Single-use catheters (the large majority today) should be disposed of in a waste bin after each use — do not flush. If you use reusable catheters, follow your provider's cleaning instructions.

How Often to Catheterize

Most people catheterize 4–6 times per day. The goal is to drain the bladder before it reaches a volume that would cause discomfort or risk of overdistension (typically 400–500 mL). Your urologist or continence specialist will prescribe a specific catheterization schedule based on your bladder capacity and fluid intake. Over time, you may develop a sense of when your bladder is approaching fullness.

A common schedule: upon waking, mid-morning, midday, mid-afternoon, evening, and before bed. Adjust timing based on fluid intake — if you drink more than usual, catheterize more frequently to prevent overdistension.

Preventing Urinary Tract Infections

UTIs are the most common complication of intermittent catheterization. The following practices significantly reduce infection risk:

• Rigorous hand washing before every catheterization — this is the single most effective measure
• Use hydrophilic or closed-system catheters — both are associated with lower UTI rates in long-term users compared to uncoated catheters
• Catheterize frequently enough — allowing the bladder to overdistend damages the bladder wall and increases infection risk
• Stay well hydrated — adequate fluid intake keeps urine dilute, which is naturally protective
• Use single-use catheters — reuse of single-use catheters increases infection risk
• Never force the catheter — trauma to the urethra increases infection risk

Signs of UTI to watch for include cloudy or foul-smelling urine, increased spasticity (in spinal cord injury), fever, increased bladder spasms, or (if you have sensation) burning or pain. Report suspected UTIs to your healthcare provider promptly — early treatment prevents complications.

Insurance Coverage for Catheters

Intermittent catheters are covered by Medicare Part B as durable medical equipment (DME) when prescribed by a physician for a qualifying condition. Medicare generally covers up to 200 catheters per month. Medicaid programs in most states also cover intermittent catheters. Most private insurance plans cover medically prescribed catheters as well. You will need a prescription, proof of medical necessity, and potentially documentation from your urologist. Many catheter suppliers provide insurance billing support — ask when ordering.

Living Well with Intermittent Catheterization

Many people initially worry that catheterization will restrict their activities or affect their quality of life. In practice, the opposite is usually true: by providing reliable bladder management, intermittent catheterization allows people to engage in social, professional, and recreational activities with far more confidence than unmanaged bladder dysfunction allows.

Travel-size compact catheters and discreet packaging make catheterization possible in nearly any setting. Many IC users keep a small kit in a bag or pocket at all times. With practice, the entire procedure takes 3–5 minutes and can be done in a standard bathroom stall.

Support resources include the United Spinal Association, the Simon Foundation for Continence, and condition-specific organizations for MS, spinal cord injury, and spina bifida, which offer peer support from others who self-catheterize.
