Urethral Lacunae Abscess

A urethral lacunae abscess is an accumulation of pus within the urethral lacunae—the small, recessed areas found along the urethra. These abscesses result from infection, leading to inflammation and the formation of pus as the body attempts to fight off the bacteria or other pathogens.

The urethra is a tube that carries urine from the bladder out of the body. In males, it also transports semen. The urethral mucosa has several small pockets or lacunae, which can become trapped sites for infections, leading to abscess formation.

Pathophysiology

Structure

The urethra consists of several layers:

1. Mucosa: The inner lining with folds and lacunae.
2. Submucosa: Connective tissue supporting the mucosa.
3. Muscularis: Muscle layers aiding in urine transport.
4. Adventitia: Outer connective tissue layer.

Blood Supply

The urethra receives blood from:

• Internal pudendal arteries
• Bulbar arteries
• Dorsal arteries

Adequate blood flow is essential for delivering immune cells to fight infections.

Nerve Supply

Nerve fibers from the pelvic plexus provide sensory and motor control to the urethra, regulating functions like urine flow and sensation.

Types of Urethral Lacunae Abscess

1. Anterior Urethral Abscess: Located in the front part of the urethra, more common in males.
2. Posterior Urethral Abscess: Located in the back part, near the bladder.

Causes of Urethral Lacunae Abscess
