A male external catheter (commonly known as a condom catheter or Uridom) is a non-invasive, sheath-like device that rolls over the penis to manage urinary incontinence. Unlike indwelling Foley catheters, it does not enter the bladder, significantly lowering the risk of urinary tract infections (UTIs).
Because proper sizing is critical to prevent leaks or skin restriction, always verify your measurements using the brand's specific printable sizing guide.
Key Selection Considerations
-
Material Choice: Silicone is translucent, breathable, and highly recommended for individuals with latex allergies or long-term wear needs. Latex is highly flexible and cost-effective but must be avoided if a latex sensitivity exists.
-
Adhesive Style: Most modern external catheters are self-adhering (one-piece) with a pressure-sensitive adhesive inner lining. Two-piece models utilize a separate, double-sided foam strip to secure the sheath.
-
Sizing Rule: To check your size, measure the diameter of the penis shaft right below the glans. If your measurement falls directly between two sizes on a brand's guide, choose the smaller size to ensure a snug fit and prevent leaking.
Core Steps for Application & Care
-
Preparation: Wash the area thoroughly with mild soap and dry completely. Do not use moisturizers or oils, as they block the adhesive. Trim pubic hair around the base of the penis if necessary to prevent painful pulling.
-
Application: Unroll the sheath down the shaft, leaving a 12 to 25 mm gap between the tip of the penis and the drainage tube to prevent friction or backflow. Gently squeeze the sheath for a few seconds to securely activate the skin-friendly adhesive.
-
Bag Connection: Attach the funnel end to a daytime leg bag or a nighttime drainage container, keeping the tubing completely straight without any kinks to preserve free urine flow.
-
Removal: Change the device daily (maximum 24-hour wear time). Apply a warm, damp cloth or use soap and water around the adhesive to easily roll the sheath off without tearing the skin.
