The urethra is the tube that completes pee of the body. This tube can become thin and cause trouble and distress when a man pees. This condition is called urethral stricture. Sometimes, a urethral stricture might require quick clinical consideration. Urethral stricture is a restricting of the urethra. Your urethra is the tube that brings pee from the bladder through the penis and out the urethral meatus (the opening at the tip of the penis) during pee.
