Catheters
661 products
Catheters refer to a flexible tube that is inserted through a narrow opening into a cavity of the body, particularly the bladder, for the process of removing fluid. Catheters connect to a drainage bag and come in many sizes and types. These can be made of rubber, PVC or plastic, or silicone. They are generally necessary when a person is unable to empty their bladder because of a condition or for the ease of doing certain procedures i.e. surgery.
With catheters, it is easy and seamless for urine to leave the body. This will help put less pressure on the kidneys and prevent any permanent damage from being sustained. Most catheters are used until the person regains the ability to urinate on their own, unless dealing with conditions related to age or a permanent injury that may need a catheter a much longer time or permanently.
3 Types of Urinary Catheters
When utilizing a catheter, it is important to know the different types available to ensure that the specific one used for your procedure is the most viable option out of the bunch. As with all other medical equipment, some types more than others will be advantageous in certain situations. Here are the three main types of urinary catheters:
Intermittent Catheters
Intermittent catheters are often used on people who only need catheters after surgery, because of its easy application and removal. These catheters are immediately removed after the bladder empties, which is why the medical professionals call it the in-and-out catheter. In the home setting, people are trained to apply the catheter themselves or with minimal supervision from a caregiver. This is done either through the urethra or through a hole in the lower abdomen.
External Catheters
External catheters are placed outside of the body and are typically used to help men who don’t have urinary retention issues, but may have functional or mental conditions such as dementia. Also called the condom catheter, this device covers the penis head and includes a tube that leads from the condom device and directly into a drainage bag.
In comparison to other catheters, these are more comfortable and carry a significantly lower risk of infections than its long-term counterpart. Some brands of external catheters are designed for long-term use but others need to be changed daily, which can cause skin irritation because of the repeated application and removal process.
Urethral or Suprapubic Catheters
Urethral or suprapubic catheters reside in the bladder. Also known as a Foley or indwelling catheter, this type can be used for short and long periods of time. This type may be the most recognizable catheter to most of us.
Urethral catheters, as the name suggests, are typically inserted through the urethra and into the bladder. Its other version, the suprapubic catheter, like the intermittent catheter, may be inserted through a tiny hole in the abdomen into the bladder. A tiny balloon at the end of the catheter is inflated with water to prevent the tube from sliding out of the body. This is then deflated when it needs to be removed.
Catheters present an easy and efficient way for persons with urinary issues to remove fluids from their body, and can also be equally helpful in surgical procedures. Knowing the type of catheter you will need for your condition will help you take care of it and lessen the chances of infection or any uncomfortability.
