Urethral Lacunae Injury

The urethra is a tube that carries urine from the bladder out of the body. Within the urethra, there are small recessed areas called lacunae. These lacunae are natural indentations or pockets that play a role in the function of the urethra.

Urethral lacunae injury occurs when these recessed areas in the urethra are damaged due to trauma, infection, or other medical conditions. Such injuries can disrupt normal urinary flow and lead to complications like urinary retention, infections, and pain.

Pathophysiology

Structure

The urethra is divided into different parts:

• Prostatic Urethra: Passes through the prostate gland.
• Membranous Urethra: Short segment between the prostate and the bulbous urethra.
• Spongy (Penile) Urethra: Runs through the penis and includes the lacunae.

Urethral lacunae are found within the spongy urethra and are areas where the urethral lining is recessed, allowing for flexibility and expansion during urination.

Blood Supply

The urethra receives blood from:

• Bulbar Artery
• Cavernous Artery

Adequate blood flow is essential for healing and maintaining the health of the urethral tissues.

Nerve Supply

The urethra is innervated by:

• Pudendal Nerve
• Pelvic Nerve

These nerves control urinary functions and sensations within the urethra.

Types of Urethral Lacunae Injuries

1. Traumatic Injury: Caused by physical trauma such as accidents or surgical procedures.
2. Infectious Injury: Resulting from severe urinary infections.
3. Inflammatory Injury: Due to chronic inflammation or autoimmune conditions.
4. Ischemic Injury: Caused by reduced blood flow to the urethral tissues.
5. Iatrogenic Injury: Resulting from medical interventions like catheterization.
