The external urethral sphincter tumor is a rare type of growth that affects the muscles around the urethra, which is the tube responsible for carrying urine out of the body. These tumors can impact the function of the urethra, causing significant urinary and other health issues.
The external urethral sphincter is a muscle that surrounds the urethra. It plays a crucial role in controlling the release of urine from the bladder. When you urinate, this muscle relaxes to allow urine to pass through the urethra and exit the body. When you hold your urine, this muscle contracts.
Pathophysiology: Structure, Blood, and Nerve Supply
Structure
The external urethral sphincter is a striated muscle, which means it is under voluntary control. This means a person can consciously control the contraction and relaxation of this muscle.
Blood Supply
The blood supply to the external urethral sphincter is provided by branches of the internal pudendal artery, which is a branch of the iliac artery. This artery delivers oxygen and nutrients necessary for the muscle’s function.
Nerve Supply
The nerve supply to this muscle comes from the pudendal nerve, which originates from the sacral nerves. The pudendal nerve allows for the voluntary control of the sphincter, enabling us to control when to urinate.
Types of External Urethral Sphincter Tumors
External urethral sphincter tumors can be broadly categorized based on their type and origin:
- Benign Tumors
These are non-cancerous growths that may cause mild to severe symptoms depending on their size and location. - Malignant Tumors
Cancerous tumors that have the potential to spread (metastasize) to other areas of the body. These are rare but dangerous. - Neurogenic Tumors
Tumors that affect the nerve tissue of the sphincter. - Fibromas
Benign tumors made of fibrous tissue that can develop in the sphincter region. - Leiomyomas
Tumors made of smooth muscle tissue that can occur in the sphincter. - Adenomas
Benign glandular tumors that could form in the sphincter area. - Cysts
Fluid-filled sacs that may develop near the sphincter, causing irritation and pressure.
Causes of External Urethral Sphincter Tumors
External urethral sphincter tumors are rare, and their exact cause is often unclear. However, several factors can contribute to the development of these tumors:
- Genetic mutations
- Chronic inflammation
- Trauma or injury to the pelvic area
- Hormonal imbalances
- Exposure to carcinogens
- A history of radiation therapy
- Viral infections (e.g., human papillomavirus)
- A history of pelvic surgery
- Age (tumors tend to be more common in older individuals)
- Autoimmune diseases
- Poor diet (lack of essential vitamins)
- Obesity
- Chronic stress
- Smoking
- Excessive alcohol consumption
- Exposure to toxins
- Chronic urinary retention
- Family history of cancer
- Infections (e.g., sexually transmitted diseases)
- Previous cancer treatments (chemotherapy)
