The urethra is the tube that allows urine to pass out of the body. In men, it's a long tube that runs through the penis. It also carries semen in men. In women, it's short and is just above the vagina. Urethral problems may happen due to aging, illness, or injury. They include:

• Urethral cancer - a rare cancer that happens more often in men
• Urethral stricture - a narrowing of the opening of the urethra
• Urethritis - inflammation of the urethra, sometimes caused by infection

Urethral problems may cause pain or difficulty passing urine. You may also have bleeding or discharge from the urethra.
