Most often referring to a urine-containment device, an external catheter is affixed via sheath over the penis, carrying urine to an attached drainage bag. The sheath or sleeve that fits over the penis is like a condom. So other names for an external catheter can be urinary sheath, penile sheath or condom catheter.

Why would I need an external catheter?

Any man who needs to prevent wetness resulting from permanent or temporary incontinence may find an external catheter necessary. Especially if residual urine in the bladder (post-voiding) is not a problem. Men who benefit from an external catheter are those who have sustained sphincter damage after prostate surgery, who experience reflexive voiding following a spinal cord injury, those who are unable to reach the toilet in time or are experiencing frequency and urgency problems, poor mobility or vision, dementia or other factors that make getting to the toilet inconvenient or unsafe.

When is an external catheter not appropriate?

If you have skin irritations or open sores on the penis, an allergy to latex or adhesive, or a risk of trauma because of an improperly used catheter.

What types of external catheters are there?

Inflatable catheters: these have a retention ring that is inflated to secure it, and deflated to remove.

Adhesive pouch: A pouch secured at the base of the penis

One-piece self-adhesive: The sheath adheres to the penis. This type tends to be easier to apply and more secure.

Two-piece: Using latex strips, eyelets and buttons; silicone or adhesive strips; adhesives that are brushed or sprayed on; or elasticized tape.

Reusable: affixed with special briefs or supported with straps

These items are all readily available at medical supplies stores.

What size of catheter do I need?

Diameters range from 20-40 millimeters in 5 and 10-mm increments; short and regular lengths

How will I know if an external catheter is right for me?

Your health care providers, physician, partner and yourself should assess whether this is right for you based on your level of caregiver and family support, your dexterity and mobility, the volume and pattern of your incontinence, and your cognitive and sensory status. If you are allergic to latex, this will limit your options. Your motivation and that of your caregivers and health-care supporters is an important consideration. Your skin will need to be checked and assessed regularly.

How long can I wear an external catheter?

Commonly, 12 to 72 hours, although some patients can tolerate longer wear times without skin damage.
