What are Urinary Catheters? Kinds of Urinary Catheters and their Usages

Urinary catheters are medical devices that are used to drain urine from the bladder when the body is unable to do so on its own. They are typically made of flexible materials such as silicone, latex, or rubber, and are inserted through the urethra into the bladder. Catheters come in a variety of sizes and types, each designed for different needs and situations.

Here are some of the different types of urinary catheters and their usages in the United States:

  • Intermittent Catheters: These catheters are used to drain the bladder periodically, typically every 4 to 6 hours. They are often used by patients who have urinary incontinence, spinal cord injuries, or other conditions that make it difficult to empty the bladder. Intermittent catheters are available in both male and female styles.
  • Foley Catheters: These catheters are also known as indwelling catheters and are inserted into the bladder and left in place for an extended period, typically up to 30 days. Foley catheters have a balloon at the end that is inflated with sterile water to hold the catheter in place. They are often used for patients who have had surgery, are bedridden, or are unable to empty their bladder on their own.
  • External Catheters: External catheters, also known as condom catheters, are used for male patients who have urinary incontinence. They are worn on the outside of the body and are secured in place with an adhesive strip. The catheter is connected to a drainage bag that can be worn on the leg or attached to a bedside collection bag.
  • Suprapubic Catheters: Suprapubic catheters are inserted through a small incision in the lower abdomen directly into the bladder. They are often used for patients who have blockages or other issues that make it difficult to insert a catheter through the urethra. Suprapubic catheters are typically left in place for an extended period.
  • Coude Catheters: These catheters have a curved tip that makes them easier to insert for patients who have an enlarged prostate or other issues that make it difficult to insert a straight catheter. Coude catheters are typically used in male patients.

Urinary catheters can be an important tool for managing urinary issues and maintaining bladder health. However, they do carry some risks, such as infection, blockages, and damage to the bladder or urethra. It is important to work closely with a healthcare provider to determine which type of catheter is right for you and to receive proper training on how to use and care for the catheter.
