All About Catheter Eyelets

all about intermittent catheter eyelets

When considering the brand or type of urinary catheter you’ll be using, the eyelets might not be the first thing you think of as an important feature. As a matter of fact, the quality, size, and placement of the eyelets can add or detract greatly from your overall catheterization experience. We hope to offer you a more detailed explanation of why that is, as well as the possible options that are available so that you, together with your prescribing health professional, can make the right decision on what intermittent catheter may work best for you.

What Are Catheter Eyelets?

The eyelets of a catheter are the small holes located typically on or around the insertion tip of an intermittent catheter. These are placed here so that when the catheter enters the bladder, the urine can enter the passage of the catheter tube and then drain out accordingly.

Punched Vs. Polished Catheter Eyelets

One way to create a catheter eyelet is by literally punching a hole in the material, sometimes called “cold-punching.” While this will create eyelets that do their intended job, some catheter-users find that punched eyelets are a little rougher and the edges can create some discomfort as the catheter moves through their urethra.

Many catheter products being manufactured today have eyelets that are polished. Polishing the holes makes the edges much smoother, which allows for a more comfortable catheterization with less friction.

Size and Shape of Catheter Eyelets

The catheter eyelets can vary from brand to brand in terms of shape and size. Larger eyelets may allow urine to drain a little faster, as will having two or more eyelets versus just one. Smaller or fewer eyelets will allow the urine to flow a little more slowly from one’s bladder. However, this also depends upon the brand itself, as some catheter types may also have more narrow interior passages due to their unique layering, which could also account for slower drainage.

Another point to take into consideration is that the shape of the catheter eyelets may also play a role in how comfortable a catheter may feel. In an in vitro study in 2014, researchers looked at how eyelet shape affects the surface tissue of the urethra. It was determined that wider drainage eyelets allowed more tissue to dip into the hole, which may create a feeling of discomfort, irritation, or friction. This might be another aspect to consider when looking at your catheter options.
