A Foley catheter should be secured to the upper thigh using either an adhesive stabilization device or an elastic leg strap, with roughly one inch of slack between the insertion site and the point where the catheter is held in place. The CDC recommends proper securement after insertion to prevent movement and urethral traction, and getting this right matters more than most people realize. An unsecured or poorly secured catheter can tug on the urethra during everyday movement, leading to pain, bladder spasms, and in severe cases, erosion of tissue.
Why Securement Matters
When a Foley catheter moves freely, any shift in body position, a turn in bed, or a step while walking can pull the catheter against the inside of the urethra. Over time, this repeated traction causes irritation, bleeding, and increased infection risk. In people with spinal cord injuries or reduced sensation, an unsecured catheter has been documented to erode through the glans and shaft of the penis entirely, a complication described in clinical literature as a preventable “never event.” Even for short-term catheter users, the pulling sensation triggers painful bladder spasms and can damage the bladder neck.
Securing the catheter to the leg absorbs that tension before it reaches the urethra. The goal is simple: the catheter should be anchored to the body so that when you move, the pull transfers to the skin of your thigh rather than to delicate urethral tissue.
Choosing a Securement Method
There are three common options, each with trade-offs.
- Adhesive stabilization devices (such as the StatLock) use a sticky pad that attaches to the skin of your thigh. The catheter clicks or locks into a small retainer on the pad. These devices hold the catheter more reliably than tape, reduce skin damage compared to repeated taping, and are the preferred method in most hospitals. They need to be replaced about every seven days or sooner if the adhesive loosens, gets wet, or becomes soiled.
- Elastic leg straps wrap around the thigh with a Velcro closure and have a tab or channel that holds the catheter tubing. They don’t require adhesive, which makes them a better choice if your skin is fragile, easily irritated, or if you’ve had reactions to medical tape. Straps should be snug enough to stay in place but loose enough that you can slide a finger underneath.
- Medical tape is the simplest option but the least reliable. Tape loosens with sweat and movement, and repeated application and removal pulls on the outer layers of skin. If tape is your only option, use a skin barrier film underneath to protect the skin surface.
Where to Place the Securement
For most people, the catheter is secured to the front or inner upper thigh. To find the right spot, lay the catheter tubing straight along the front of the thigh with your leg fully extended, then slide the anchoring point back about one inch toward the insertion site. This creates the small loop of slack you need.
For men using a catheter long-term, securing to the lower abdomen rather than the thigh is often the better choice. Thigh placement in men routes the catheter downward, and if an erection occurs, the catheter can act like a bowstring and cut into the underside of the penis. Abdominal placement avoids this by keeping the catheter oriented in the same direction as the penis. The drainage bag still hangs below the bladder, so gravity drainage isn’t affected.
For women, the inner upper thigh is standard. The shorter urethra means there’s less tubing between the insertion site and the anchor point, so paying attention to slack is especially important.
How to Apply an Adhesive Securement Device
Start with clean, dry skin. Wash the area with a gentle, non-alcohol cleanser and let it dry completely. If you’re using a skin barrier film (a liquid that dries into a thin protective layer), apply it now and let it dry for about 30 seconds. This film sits between the adhesive and your skin, so when you eventually peel off the device, it pulls the film away instead of stripping skin cells.
Peel the backing off the adhesive pad and press it firmly onto the prepared skin. With your leg fully extended, lay the catheter tubing into the retainer, leaving one inch of slack between the urethral insertion site and the device. That inch of slack is critical. It’s what absorbs movement when you bend your leg, roll over, or stand up. Without it, every motion transfers directly to the urethra.
Lock or snap the retainer closed over the tubing. Run your finger along the edges of the adhesive pad to make sure it’s sealed to the skin. The tubing from the device to the drainage bag should drape freely without kinks.
How to Apply an Elastic Leg Strap
Wrap the strap around your upper thigh and fasten the Velcro. It should be firm but not tight. You should be able to slide one finger between the strap and your skin. Thread the catheter tubing through the holding tab, again leaving about one inch of slack between the insertion site and the strap. Check that the strap isn’t compressing the tubing, which would block urine flow.
Elastic straps tend to migrate down the leg over the course of a day, especially if you’re moving around. Check the position periodically and readjust when needed. Some people find it helpful to place a small piece of skin-friendly tape on the strap’s edge to keep it from sliding.
Protecting Your Skin
The thigh skin under any securement device takes a beating over time. Adhesive pulls at the surface layer each time you change the device. Straps can trap moisture and cause friction. A few practices make a meaningful difference.
Alternate the securement site slightly with each change, moving the device an inch or two from the previous spot. This gives irritated skin time to recover. Keep the area moisturized between device changes using a simple emollient like petroleum jelly or glycerin-based cream, but make sure the skin is clean and dry before applying a new adhesive pad (moisturizer residue will prevent the adhesive from sticking).
If you notice redness, blistering, or skin that looks like it’s tearing when you remove the adhesive, switch to a solvent-free barrier film before your next application. These films have been shown to be more effective and more economical at preventing skin breakdown from adhesive removal compared to solvent-based products. For people with very fragile skin, switching to an elastic strap may be the better long-term option.
When to Replace the Securement
Adhesive stabilization devices should be changed every seven days under normal conditions. Replace them sooner if the adhesive is peeling up at the edges, if the pad gets wet from bathing or sweat, or if it becomes soiled. A device that’s starting to lift isn’t doing its job, and a partially detached anchor is almost as bad as no anchor at all.
Elastic straps should be washed regularly with mild soap, as they sit against skin that sweats. Most manufacturers recommend having two straps so you can rotate between them. Inspect the Velcro and elastic for wear; once a strap no longer holds firmly, replace it.
Each time you change the securement, take a moment to check the skin underneath for redness, breakdown, or signs of infection. Also check the catheter itself for any crusting or buildup near the insertion site, and gently clean the area.
Common Mistakes to Avoid
The most frequent error is securing the catheter with no slack. When the tubing runs in a straight, taut line from the urethra to the anchor, every leg movement pulls directly on the bladder neck. One inch of slack, checked with the leg fully extended, prevents this.
Another common mistake is anchoring the catheter to the bed rail or wheelchair instead of the body. This creates the exact problem securement is supposed to solve: when you move and the anchor doesn’t move with you, the catheter pulls. Always secure to the body first. If you need to route tubing to a drainage bag hung on a bed frame, leave additional slack in the tubing between the leg anchor and the bag.
Finally, don’t let the drainage bag sit higher than your bladder. Securement keeps the catheter from pulling, but proper bag positioning keeps urine flowing in the right direction. The bag should always hang below bladder level, whether you’re lying down, sitting, or standing.
