The external urethral sphincter is a critical part of the body’s urinary system. It is a muscle that helps control the flow of urine from the bladder. When masses (or abnormal growths) form in or around this area, they can cause various symptoms, disrupting normal urinary function. In this article, we will explore everything you need to know about external urethral sphincter masses, including their structure, blood and nerve supply, causes, symptoms, diagnosis, treatment, and prevention.
The external urethral sphincter is a ring of muscle that surrounds the urethra, which is the tube through which urine passes from the bladder to the outside of the body. The sphincter controls the release of urine, and you can consciously tighten or relax it. This muscle is important for maintaining urinary continence (the ability to hold urine in the bladder).
Pathophysiology of External Urethral Sphincter Masses
Structure:
The external urethral sphincter is made up of skeletal muscle fibers, meaning it is under voluntary control. This muscle surrounds the urethra and is located at the lower end of the bladder.
Blood Supply:
The external urethral sphincter receives its blood supply from branches of the internal pudendal artery, a key vessel that supplies the pelvic organs.
Nerve Supply:
The sphincter is innervated by the pudendal nerve, which controls many pelvic muscles and contributes to sensations in the genital region.
Types of External Urethral Sphincter Masses
- Benign Tumors:
These are non-cancerous growths that may appear in or around the urethral sphincter. They tend to grow slowly and may not cause immediate symptoms. - Malignant Tumors:
Malignant or cancerous growths can develop in the external urethral sphincter or nearby tissues. These tumors may spread to other parts of the body. - Cysts:
Cysts are fluid-filled sacs that can form in the tissues surrounding the sphincter. - Fibromas:
Fibromas are benign tumors made up of fibrous or connective tissue. These can develop around the external urethral sphincter. - Muscle Masses:
Muscle tissue can form abnormal growths around the sphincter, which may interfere with normal function. - Abscesses:
A collection of pus that forms due to an infection in or around the urethral sphincter. These can cause pain and swelling.
Causes of External Urethral Sphincter Masses
- Infection:
Infections can cause swelling and abscess formation around the urethra, leading to masses. - Trauma:
Physical injury to the area may lead to the formation of masses or growths. - Cancer:
Cancerous growths, such as squamous cell carcinoma or urothelial carcinoma, can form in or around the sphincter. - Chronic Inflammation:
Long-term irritation or inflammation can contribute to abnormal tissue growth. - Endometriosis:
In women, endometrial tissue growing outside the uterus may affect the urethra and sphincter. - Cystic Lesions:
Fluid-filled cysts can develop in the tissue surrounding the sphincter. - Congenital Abnormalities:
Some people may be born with abnormal tissue growths in the area. - Pelvic Floor Disorders:
Disorders affecting the pelvic floor muscles can lead to mass formation around the urethral sphincter. - Hormonal Imbalances:
Hormonal changes, especially during pregnancy or menopause, can cause tissue growth or changes around the sphincter. - Pelvic Organ Prolapse:
This condition occurs when pelvic organs descend into the vaginal or urethral area, which may cause masses to form. - Prostatitis:
Inflammation of the prostate gland can extend to nearby structures, including the sphincter. - Obesity:
Excess weight can increase pressure on the pelvic area, leading to the formation of masses. - Diabetes:
Chronic high blood sugar levels may contribute to tissue growth and complications in the urinary system. - Previous Surgery:
Surgical procedures in the pelvic area can lead to the development of scar tissue, which may cause masses. - Viral Infections:
Certain viral infections, such as human papillomavirus (HPV), may lead to abnormal growths around the urethra. - Autoimmune Diseases:
Conditions like lupus or rheumatoid arthritis can lead to inflammation and abnormal growth in the area. - Obstruction of Urine Flow:
Blockages can lead to swelling and abnormal growths as the body compensates for reduced urine flow. - Aging:
As people age, the tissues around the urethra can change, leading to the formation of masses. - Radiation Therapy:

Some people may be genetically predisposed to developing tumors or masses in the urethral area.
