External Urethral Sphincter Necrosis refers to a severe condition where the muscles responsible for controlling urination (external urethral sphincter) suffer from damage or death (necrosis). This can lead to loss of urinary control and other significant health issues.
Pathophysiology (Structure, Blood, Nerve Supply)
- Structure: The external urethral sphincter is a muscle that surrounds the urethra (the tube through which urine exits the body). It helps control the release of urine.
- Blood Supply: The blood flow to the external urethral sphincter comes from the internal pudendal artery, which provides oxygen and nutrients to the muscle.
- Nerve Supply: The muscle is controlled by the pudendal nerve, which helps send signals from the brain for urination control.
When this system is disrupted, either by injury or disease, the muscle can die or stop functioning, resulting in incontinence.
Types of External Urethral Sphincter Necrosis
- Acute Necrosis: Sudden and severe death of muscle tissue, often due to trauma or infection.
- Chronic Necrosis: A slow, progressive breakdown of muscle tissue, often seen in long-term conditions like diabetes.
