External catheters, also sometimes referred to as condom catheters, penile sheaths, or urinary sheaths, are an invaluable part of incontinence management for millions of men.
There are many variations available and styles, materials, and other details vary by manufacturer, but the basic premise of these devices remains the same: a urine containment device fits over the penis and collects urine, either in an integral pouch or in drainage bag which is attached to the containment device.
The most common system configurations use a soft, flexible latex, polyvinyl, or silicone sheath that fits over the penis like a condom and is affixed with some type of adhesive, which is often "built into" the shealth itself. A length of tubing connects the sheath to a drainage bag, which is generally affixed to the leg with adjustable straps.
Variations on this system include two-piece sheaths, non-self-adhesive sheaths that are secured with strips, tape, or self-applied adhesive, and reusable collection devices that are held in place over the penis with straps, belts, or special briefs.
In addition, a variation designed for use by men with a retracted penis (common in the elderly) is available. This variation uses an adhesive urinary pouch, much like an ostomy pouch, that is affixed at the base of the penis.
Like all aspects of incontinence management, these systems have both advantages and disadvantages and may not be suitable for every person or every situation.
As with all incontinence management tools, there are some important factors to take into consideration. Sheaths come in a variety of sizes, and using the correct size is essential to getting the most from the product. Sizing differs among manufacturers, so be sure to consult the sizing tables for the product you are considering.
Learning to use a sheath system can take some time and may require some initial training. Consult with your physician before using this type of system.
