A urethral corpus cavernosum abscess is a rare condition in which a pocket of pus (an abscess) forms in the erectile tissue (corpus cavernosum) of the penis—often in relation to a urethral injury or infection. This article explains what this condition is, how it develops, its causes and symptoms, how doctors diagnose it, and the many treatment and prevention options available.
A urethral corpus cavernosum abscess is an infection that leads to the formation of a pus-filled cavity within the corpus cavernosum of the penis. In many cases, it can result from trauma to the urethra (the tube that carries urine and semen) or from a spreading infection. Because the penis is made of highly vascular (rich in blood vessels) and sensitive tissue, such infections can be serious and may affect both urinary and sexual functions if not treated promptly.
Key Points:
- Abscess: A localized collection of pus caused by infection.
- Corpus Cavernosum: Two sponge-like regions of erectile tissue in the penis that fill with blood during an erection.
- Urethral Involvement: In some cases, an abscess in the corpus cavernosum originates near the urethra (the urethral aspect) due to injury or infection spreading from the urethra.
Anatomy and Pathophysiology
Understanding the basic structure of the penis and how it functions helps explain why an abscess here is concerning.
Structure of the Penis
- Corpora Cavernosa:
- Two large, cylindrical masses of erectile tissue.
- Fill with blood to produce an erection.
- Rich in tiny blood vessels (cavernous sinuses) and smooth muscle fibers.
- Corpus Spongiosum:
- A smaller mass of tissue that surrounds the urethra.
- Ends in the glans (head of the penis).
- Urethra:
- The tube that runs through the corpus spongiosum.
- Carries urine and semen outside the body.
Blood Supply and Nerve Supply
- Blood Supply:
- The penis receives blood from the internal pudendal artery.
- During an erection, increased blood flow fills the cavernous sinuses.
- Venous outflow is reduced (veins are compressed), which maintains the erection.
- Nerve Supply:
- The dorsal nerve of the penis and pelvic nerves supply sensation.
- These nerves are involved in both the sensation and the regulation of blood flow.
Functions of the Corpus Cavernosum
- Erection:
- Blood fills the corpora cavernosa, making the penis firm.
- Sexual Function:
- Plays a critical role in sexual performance and reproduction.
- Urinary Function (Indirectly):
- The surrounding tissues help maintain the position and function of the urethra.
Pathophysiology of an Abscess Formation
- Infection Onset:
- Bacteria or other microorganisms enter the tissue—often after trauma, catheterization, or an untreated infection.
- Inflammatory Response:
- The body sends white blood cells to fight the infection.
- Pus Formation:
- As immune cells accumulate and bacteria die, pus (dead cells, bacteria, and tissue debris) forms a collection within the tissue.
- Local Effects:
- The abscess can compress nearby structures, cause pain, and disturb blood flow and nerve function.
Types of Urethral Corpus Cavernosum Abscess
While this abscess is rare, it may be classified based on its extent and cause:
- Localized Abscess:
- Confined to a small area within the corpus cavernosum.
- Extensive Abscess:
- Involves a larger portion of the corpus cavernosum.
- Secondary Abscess:
- Arises due to a primary infection elsewhere (e.g., urethral diverticulum perforation or catheter-related trauma).
- Post-Traumatic Abscess:
- Develops following a specific injury or invasive procedure.
Causes of Urethral Corpus Cavernosum Abscess
Here are 20 possible causes or risk factors for developing a urethral corpus cavernosum abscess:
- Urethral Trauma: Injury from accidental injury or vigorous catheterization.
- Self-Catheterization Errors: Incorrect technique causing urethral perforation.
- Penile Injection: Use of injection therapies for erectile dysfunction.
- Urethral Diverticulum Perforation: A pouch in the urethra that ruptures.
- Sexually Transmitted Infections (STIs): Infections like gonorrhea or chlamydia spreading locally.
- Bacterial Urinary Tract Infection (UTI): Infection that spreads to surrounding tissues.
- Penile Trauma: Accidents, falls, or blunt force injuries.
- Iatrogenic Injury: Injury caused during a medical procedure (e.g., prostate surgery).
