External Urethral Meatus Injury refers to damage or trauma to the external opening of the urethra, known as the meatus. This injury can affect urinary function and may result from various causes, requiring medical attention for proper diagnosis and treatment.
The external urethral meatus is the external opening of the urethra through which urine exits the body. In males, it is located at the tip of the penis, while in females, it is situated above the vaginal opening. Injury to this area can disrupt normal urinary function and may lead to complications if not addressed promptly.
Pathophysiology
Structure
The external urethral meatus is a small, funnel-shaped opening leading to the urethra. In males, it is part of the penile anatomy, whereas in females, it is part of the vulvar structure. The meatus is surrounded by tissues that provide protection and facilitate urine flow.
Blood Supply
The blood supply to the external urethral meatus comes from branches of the pudendal artery. Adequate blood flow is essential for tissue health and healing after an injury.
Nerve Supply
Sensory nerves from the pudendal nerve provide sensation to the external urethral meatus. These nerves are responsible for feeling pain, temperature, and touch in the area.
Types of External Urethral Meatus Injuries
- Lacerations: Cuts or tears in the meatus.
- Abrasion: Superficial scraping or wearing away of the tissue.
- Avulsion: Severe tearing away of the meatus from surrounding tissues.
- Traumatic Hematoma: Blood pooling due to injury.
- Infections: Resulting from trauma leading to bacterial growth.
- Scar Tissue Formation: Excessive healing leading to tight or fibrous tissue.
- Foreign Body Injuries: Objects causing damage to the meatus.
- Chemical Burns: Exposure to harmful substances.
- Thermal Burns: Injury from heat or cold.
