Prostatic Utricle Obstruction

The prostatic utricle is a small, blind-ending pouch in the prostate gland, a part of the male reproductive system. It is a remnant of embryonic development and is typically small in size. Prostatic utricle obstruction occurs when this pouch becomes blocked, leading to various urinary and reproductive issues.

Pathophysiology

Structure

The prostatic utricle is located in the midline of the prostate, near the verumontanum—a landmark in the male urethra?. It is connected to the urethra and can vary in size from a tiny dimple to a larger, more noticeable pouch.

Blood Supply

The prostatic utricle receives its blood supply from branches of the inferior vesical artery?, which ensures adequate blood flow to the prostate and surrounding structures.

Nerve Supply

Nerve fibers from the pelvic plexus innervate the prostatic utricle, providing sensation and control over urinary functions.

Types of Prostatic Utricle Obstruction

1. Congenital? Obstruction: Present at birth due to developmental anomalies.
2. Acquired Obstruction: Develops later in life, often due to trauma? or infection?.
3. Isolated Utricle Obstruction: Blockage confined solely to the prostatic utricle.
4. Associated Urethral Obstruction: Occurs alongside blockages in other parts of the urethra.
