Male External Catheter Sizing

Male external catheters (also known as condom catheters) are often used temporarily as an alternative to indwelling Foley catheters or other incontinence products such as liners, pull-ups, and diapers.

Some indications for use are reflexive voiding due to spinal cord injuries, decreased mobility, and unmanageable urinary frequency or urgency.

When using male external catheters, it is important to use the correct size and to practice proper preparation, application, and removal techniques to prevent leaking and skin damage.

Leakage may result if the catheter is too loose, but constriction may occur if it is too tight. Male external catheters are flexible and the right size should be snug but not overly tight.

Here are some helpful tips to help you choose the correct size:

  • To get the right fit, measure the circumference of the penis with a size guide or metric measuring tape.
  • The penis should be measured in its relaxed flaccid state at the widest spot. If the measurement rangers between two sizes, the smaller-sized MEC will most often be more comfortable and work better. The larger of the two sizes may become loose and come off or allow urine leakage, leading to skin damage and complications over time.
  • A size that is too small or too tight can cause constriction, restriction of blood flow or obstruction.

It may take some trial and error to find the size that works best.
