urinary catheter

A urinary catheter is a flexible tube inserted into the bladder through the urethra to drain urine when a person cannot do so naturally. It is commonly used during surgeries, for medical exams, or when a person has difficulty urinating due to injury or illness. The catheter helps ensure the bladder is emptied correctly and prevents complications like infections or bladder damage. Medical professionals take care to insert and remove it carefully and maintain hygiene to reduce risks. Overall, it is a useful medical device that supports normal bodily function when necessary.
