External Urethral Sphincter Hematoma

An external urethral sphincter hematoma refers to the accumulation of blood around the external urethral sphincter muscle. The external urethral sphincter is a crucial muscle located around the urethra, responsible for controlling the release of urine from the bladder. When a hematoma forms in this area, it can cause pain, swelling, and urinary difficulties.

Key Points:

• Hematoma: A collection of blood outside blood vessels, usually caused by injury or trauma.
• External Urethral Sphincter: A muscle that controls urine flow from the bladder through the urethra.

Pathophysiology

Understanding the pathophysiology helps in comprehending how an external urethral sphincter hematoma develops and affects the body.

Structure

The external urethral sphincter is part of the pelvic floor muscles. It surrounds the urethra, the tube that carries urine from the bladder out of the body. This muscle works involuntarily to maintain continence, preventing urine leakage.

Blood Supply

The external urethral sphincter receives blood primarily from the internal pudendal artery, which branches off from the internal iliac artery. Adequate blood supply is essential for the muscle’s function and health.

Nerve Supply

Nerve control is provided by the pudendal nerve, which is responsible for both motor and sensory functions in the pelvic region. Proper nerve function ensures the sphincter’s ability to contract and relax appropriately.

Types of External Urethral Sphincter Hematoma

Hematomas can vary based on their size, location, and cause. Here are the primary types related to the external urethral sphincter:

1. Traumatic Hematoma: Caused by direct injury or trauma to the pelvic area.
2. Spontaneous Hematoma: Occurs without any obvious injury, often due to underlying medical conditions.
3. Post-Surgical Hematoma: Develops after surgical procedures involving the pelvic region.
4. Iatrogenic Hematoma: Resulting from medical interventions like catheterization.

Causes

External urethral sphincter hematomas can result from various factors. Here are 20 potential causes:

1. Pelvic Fractures: Breaks in the pelvic bones can damage blood vessels.
