The external urethral orifice (also known as the meatus) is the opening through which urine and, in men, semen exit the body. This article will explore what happens when this area is injured, what causes it, and how it’s treated, all in simple language to help you understand this medical condition better.
An external urethral orifice injury refers to damage or trauma to the opening at the tip of the penis or the area around it. For men, this is where urine and semen exit the body. In women, the external urethral orifice is located just above the vaginal opening, and it’s where urine is expelled from the body. An injury can cause pain, discomfort, or difficulty urinating.
Pathophysiology (Structure, Blood, Nerve Supply)
- Structure:
- In men, the external urethral orifice is located at the tip of the penis. It leads to the urethra, a tube that carries urine from the bladder to the outside of the body.
- In women, the external urethral orifice is a small opening located just in front of the vaginal opening.
- Blood Supply:
- The urethra, including the external orifice, gets its blood supply from the pudendal artery in both men and women. This artery is a branch of the internal iliac artery.
- Nerve Supply:
- The external urethral orifice has nerve endings that make it sensitive to touch and temperature. The nerves responsible for sensation in this area come from the pudendal nerve.
Types of External Urethral Orifice Injury
- Superficial Injury: A minor scratch or abrasion that affects only the surface of the external orifice.
- Penetrating Injury: A deeper injury that involves a cut or tear in the skin.
- Blunt Trauma: Injury caused by force, like a blow or impact, that may not break the skin but can cause swelling or internal damage.
- Infectious Injury: Infections in or around the external urethral orifice can cause damage to the skin and underlying tissues.
- Burns: Exposure to chemicals, hot water, or fire can cause thermal or chemical burns to the external orifice.
Causes of External Urethral Orifice Injury
