External Urethral Sphincter Diseases

The external urethral sphincter (EUS) is a muscle located around the urethra, which controls the flow of urine from the bladder. Diseases or disorders related to the external urethral sphincter can lead to various problems with urination, including incontinence, urinary retention, and more.

Pathophysiology: Structure, Blood, and Nerve Supply

• Structure: The external urethral sphincter is made up of striated muscle fibers, which allow voluntary control over urination. It surrounds the urethra, contracting to hold urine in and relaxing to allow its release.
• Blood Supply: The blood supply to the external urethral sphincter comes from the internal pudendal artery, which branches off from the iliac artery.
• Nerve Supply: The pudendal nerve is responsible for controlling the external urethral sphincter. It provides the voluntary control to contract and relax the sphincter.

Types of External Urethral Sphincter Diseases

1. Sphincter Dysfunction: Problems with the sphincter’s ability to contract or relax, leading to issues with controlling urination.
2. Sphincter Incontinence: This happens when the external urethral sphincter cannot hold back urine, resulting in involuntary leakage.
3. Sphincter Spasm?: When the sphincter contracts uncontrollably, leading to difficulty urinating or pain?.
4. Sphincter Weakness?: Loss of strength in the external urethral sphincter, often associated with aging or childbirth, which may lead to leakage of urine.
5. Sphincter Atrophy?: Gradual loss of muscle mass in the external urethral sphincter, causing a reduced ability to control urine flow.
