Urinary catheter

Urinary Catheter

A urinary catheter is a flexible tube used in medical practice to drain urine from the bladder. It is a common procedure in healthcare, particularly in situations where patients cannot urinate on their own.

Types of Urinary Catheters

There are three main types of urinary catheters: indwelling catheters, intermittent catheters, and external catheters.

Indwelling catheters (also known as Foley catheters) are inserted into the bladder through the urethra, or through a hole in the abdomen. They are typically used for long-term catheterization and can remain in place for up to three months.

Intermittent catheters are used for short-term catheterization. They are inserted through the urethra into the bladder, allowing urine to drain out, and then removed.

External catheters (also known as condom catheters) are used for men who have chronic urinary incontinence. They are worn like a condom and attached to a drainage bag.

Procedure

The procedure for inserting a urinary catheter involves sterilization of the area, application of a local anesthetic, and insertion of the catheter tube. The tube is then secured to prevent it from moving and causing discomfort or injury.

Risks and Complications

While urinary catheters are generally safe, they can sometimes lead to complications such as urinary tract infections (UTIs), bladder stones, and damage to the urethra. Long-term use can also lead to kidney damage.

Care and Maintenance

Proper care and maintenance of a urinary catheter are crucial to prevent complications. This includes regular cleaning of the catheter and the area around it, as well as regular changing of the catheter and drainage bag.
