urethral catheter

A urethral catheter is a flexible tube inserted through the urethra into the bladder to drain urine. It is commonly used when a person cannot urinate on their own due to medical conditions, surgery, or injury. The catheter allows urine to flow out of the bladder into a bag outside the body for collection and monitoring. It should be inserted carefully by a healthcare professional to prevent infection or injury. The catheter remains in place for as long as needed and is removed once normal urination resumes.
