External Urethral Sphincter Cancer is a rare type of cancer that affects the external urethral sphincter—the muscle responsible for controlling urine flow from the bladder. This guide provides a detailed yet straightforward overview of this condition, covering everything from its structure and causes to symptoms, treatments, and prevention strategies.
Pathophysiology
Understanding the pathophysiology of external urethral sphincter cancer helps in comprehending how the disease develops and affects the body.
Structure
The external urethral sphincter is a skeletal muscle located around the urethra, the tube that carries urine from the bladder out of the body. It plays a crucial role in urinary continence by contracting to prevent urine leakage.
Blood Supply
The external urethral sphincter receives blood through branches of the internal pudendal artery, ensuring it receives the necessary oxygen and nutrients to function correctly.
Nerve Supply
Nerve signals controlling the external urethral sphincter come from the pudendal nerve, which originates in the sacral region of the spinal cord. These nerves coordinate the muscle’s contraction and relaxation during urination.
Types of External Urethral Sphincter Cancer
External urethral sphincter cancer is typically categorized based on the type of cells involved and the cancer’s behavior:
- Squamous Cell Carcinoma: Originates from the flat cells lining the urethra.
- Adenocarcinoma: Develops from glandular cells that produce mucus.
- Transitional Cell Carcinoma: Arises from the transitional epithelium, which can stretch.
- Sarcoma: A rare type originating from connective tissues like muscles.
- Basal Cell Carcinoma: Less common, originating from basal cells in the urethral lining.
Causes
While the exact cause of external urethral sphincter cancer isn’t fully understood, several risk factors may increase the likelihood of developing this cancer:
- Smoking: Increases the risk of many urinary cancers.
