Self-Sealing External Catheters — What You Should Know

How do self-sealing external catheters work?

Self-sealing external catheters create a seal around the base of the penis. The adhesive used in these devices is gentle and non-irritating, but it is strong enough to keep the catheter in place. The catheter is made from a flexible material that conforms to the shape of the penis. Once in place, urine can flow through the catheter and into a collection bag, which can be attached to the catheter with a connector.

Self-sealing external catheters are designed to be easy to use. Also, they can be applied by the patient or a caregiver. They are also easy to remove, and the adhesive can easily peel off without causing skin irritation.

What are the benefits of self-sealing external catheters?

Self-sealing external catheters offer several benefits over traditional catheters. Some of the key benefits include:

  • Reduced risk of infection: Because self-sealing external catheters do not require insertion into the urethra, they carry a lower risk of infection than traditional catheters.
  • Comfort: Self-sealing external catheters are comfortable to wear and do not cause discomfort or pain, as traditional catheters can.
  • Easy to use: Self-sealing external catheters are easy to apply and remove, making them a convenient option for patients and caregivers.
  • Discreet: Self-sealing external catheters can be worn under clothing without being noticeable.

What are the potential drawbacks of self-sealing external catheters?

While self-sealing external catheters offer several benefits, there are also some potential drawbacks. These include:

  • Leaks: While the adhesive used in self-sealing external catheters is designed to create a secure seal, leaks can still occur. This can be due to improper sizing, placement, or other factors.
  • Skin irritation: While the adhesive used in self-sealing external catheters is gentle and non-irritating, some patients may still experience skin irritation or damage.
  • Cost: Self-sealing external catheters can be more expensive than traditional catheters and may not be covered by insurance.
  • Availability: Self-sealing external catheters may only be available in some areas. Patients may need to order them online or through a specialty medical supplier.
