The urethral bulb is a vital part of the urinary system, playing a key role in the passage of urine and, in males, semen. Diseases affecting the urethral bulb can lead to various urinary and sexual health issues. This guide provides detailed information on urethral bulb diseases, including their definitions, causes, symptoms, diagnostic methods, treatments, prevention strategies, and frequently asked questions (FAQs).

The urethral bulb is the expanded, widened portion at the end of the urethra, located near the external opening of the body.

• In Males: It is situated within the bulb of the penis and is part of the spongy tissue that helps with erectile function.
• In Females: It is located in the vestibule, the area between the vaginal opening and the urethral opening.

The urethral bulb plays a crucial role in controlling the flow of urine and, in males, semen during ejaculation.

Pathophysiology

Structure

• Muscular Composition: The urethral bulb is composed of smooth and skeletal muscles that facilitate the control of urine flow.
• Connective Tissue: Provides structural support and flexibility.
• Surrounding Tissues: In males, it is surrounded by the corpus spongiosum; in females, by the vestibular bulbs.

Blood Supply

• Internal Pudendal Arteries: Primary blood vessels supplying the urethral bulb, ensuring adequate blood flow for its functions.

Nerve Supply

• Pudendal Nerve: Responsible for the sensation and motor control of the urethral bulb, regulating urinary and sexual functions.
