Catheter

A urine bag, also known as a urinary drainage bag or catheter bag, is a medical device used to collect and store urine. It is commonly used by patients who have difficulty urinating on their own due to various reasons such as surgery, urinary incontinence, or bladder obstruction.

When using a urine bag, it is crucial to maintain proper hygiene by cleaning both the bag and surrounding areas regularly to minimize the risk of infection. Additionally, users should ensure they follow their healthcare provider's instructions regarding when to empty and replace the bag, as well as any other specific guidelines related to their individual situation.

In urology, a Foley catheter is a flexible tube that a clinician passes through the urethra and into the bladder to drain urine.

It is the most common type of indwelling urinary catheter. The tube has two separated channels, or lumens, running down its length.
