An internal urethral sphincter abscess is a rare but serious infection that occurs in the internal urethral sphincter, a muscle located in the urethra. The urethra is the tube that carries urine from the bladder to the outside of the body. The internal urethral sphincter is responsible for controlling the flow of urine, and an abscess here means that a collection of pus forms in this muscle due to an infection.
This condition can cause significant discomfort and complications if not treated properly. It often results from infections or injuries that affect the urethra and surrounding structures.
Pathophysiology
- Structure: The urethra has two sphincters, internal and external. The internal sphincter is involuntary, meaning it is controlled by the autonomic nervous system. It is located near the bladder and controls the initial release of urine. An abscess in this area occurs when bacteria or other pathogens invade the tissue, causing inflammation and pus accumulation.
- Blood Supply: The blood supply to the urethra comes from branches of the internal iliac artery. Blood flow is essential for delivering nutrients and oxygen to the area to fight infections and heal tissue.
- Nerve Supply: The internal sphincter is controlled by autonomic nerves, which include sympathetic and parasympathetic fibers. These nerves help regulate urine storage and release by controlling sphincter contraction and relaxation.
Types of Urethral Abscesses
- Simple Abscess: A localized collection of pus.
- Complicated Abscess: An abscess that spreads or causes damage to surrounding tissues.
- Recurrent Abscess: An abscess that reappears despite treatment.
- Periurethral Abscess: An abscess that affects the tissues around the urethra, often causing swelling and pain.
Causes of Internal Urethral Sphincter Abscess
- Urinary Tract Infection (UTI): Bacteria from a UTI can spread to the urethra, causing an abscess.
- Catheterization: Insertion of a catheter into the urethra increases the risk of infection.
- Sexual Activity: Unprotected sexual activity can introduce bacteria into the urethra.
- Poor Hygiene: Lack of proper genital hygiene can lead to infections.
- Kidney Stones: Stones can irritate the urethra and lead to infection.
- Chronic Inflammation: Conditions like prostatitis or cystitis can lead to abscess formation.
- Trauma or Injury: Any injury to the urethra can make it prone to infection.
- Surgical Procedures: Recent surgeries near the urethra may increase the risk of infection.

- Diabetes: High blood sugar levels can impair the immune system’s ability to fight infections.
- Obesity: Increases the risk of infections due to poor blood circulation and hygiene issues.
- Anal Fissures: These can lead to infections that spread to the urethra.
- Fecal Contamination: Bacteria from feces can spread to the urethra if proper hygiene is not maintained.
- Chronic Use of Antibiotics: Can disrupt the balance of normal bacteria, allowing harmful bacteria to grow.

- Urinary Retention: Prolonged retention of urine can increase bacterial growth in the urethra.
- Underlying Health Conditions: Conditions like cancer or autoimmune diseases may predispose individuals to infections.
