Prostatic Urethra Obstruction

The prostatic urethra is the section of the urethra that passes through the prostate gland. When this part of the urethra becomes narrowed or blocked, it’s called prostatic urethra obstruction. This blockage can interfere with the normal flow of urine, causing various urinary symptoms and potentially leading to complications like urinary retention or kidney damage if left untreated.

Pathophysiology

Understanding how prostatic urethra obstruction develops involves looking at the structure of the prostate, its blood and nerve supply, and how these can be affected.

Structure

• Prostate Gland: A walnut-sized gland located just below the bladder in men. It surrounds the prostatic urethra.
• Urethra: The tube that carries urine from the bladder out through the penis. It has several parts, including the prostatic urethra.

Blood Supply

• Arteries: The prostate receives blood mainly from the inferior vesical artery and the middle rectal artery.
• Veins: Blood is drained through the prostatic plexus into the internal iliac veins.

Nerve Supply

• Autonomic Nerves: These control involuntary functions like bladder contraction and relaxation.
• Pudendal Nerves: Responsible for sensation and voluntary control of the external urethral sphincter.

When the prostatic urethra becomes obstructed, it can disrupt normal blood flow and nerve signals, leading to symptoms like difficulty urinating, increased frequency, and discomfort.

Types of Prostatic Urethra Obstruction

Prostatic urethra obstruction can be classified based on its cause and characteristics:

1. Benign Prostatic Hyperplasia (BPH): Non-cancerous enlargement of the prostate gland, the most common cause.
2. Prostatic Cancer: Malignant tumors can obstruct the urethra.
3. Prostatitis: Inflammation or infection of the prostate can cause swelling and blockage.
4. Urethral Strictures: Scar tissue formation narrowing the urethra within the prostate.
5. Prostatic Stones: Calcified deposits within the prostate can block the urethra.
6. Congenital Abnormalities: Birth defects affecting the prostatic urethra.
7. Trauma: Injury to the prostate or urethra causing obstruction.
8. Radiation Therapy: Treatment for prostate cancer can lead to scarring and blockage.
9. Urethral Polyps: Non-cancerous growths within the prostatic urethra.
10. Bladder Neck Obstruction: Narrowing where the bladder meets the urethra, affecting the prostatic urethra.
