urinvägskateter

Urinvägskateter, often referred to simply as a catheter, is a medical device used to drain urine from the bladder. It consists of a flexible tube that is inserted through the urethra and into the bladder. Once in place, the catheter allows urine to flow out into a collection bag.

There are several reasons why a person might need a urinary catheter. These can include urinary retention, where the bladder is unable to empty itself, difficulty urinating due to an enlarged prostate or other obstructions, or to monitor urine output in critically ill patients. Catheters are also used during and after certain surgical procedures, or for individuals with neurological conditions that affect bladder control.

There are different types of urinary catheters. Indwelling catheters, also known as Foley catheters, are left in place for extended periods and are held in the bladder by a small balloon. Intermittent catheters are inserted only when needed to empty the bladder, and then removed immediately. External catheters, or condom catheters, are worn on the outside of the penis and are primarily used by men.

While urinary catheters can be very beneficial, they also carry potential risks, such as urinary tract infections (UTIs), bladder spasms, and discomfort. Proper hygiene and adherence to medical guidelines are crucial to minimize these risks. The insertion and management of a urinary catheter are typically performed by trained healthcare professionals.
