The urethral bulb is a part of the urinary system located at the distal end of the urethra, surrounding the vaginal opening in females and part of the penile urethra in males. Disorders of the urethral bulb can affect urinary function, causing discomfort, pain, and other complications. These disorders may arise from infections, injuries, anatomical abnormalities, or other health conditions.

Pathophysiology

Understanding the underlying mechanisms of urethral bulb disorders helps in comprehending how these conditions develop and affect the body.

Structure

The urethral bulb is a spongy area composed of erectile tissue. In females, it surrounds the vaginal opening and contributes to sexual function. In males, it is part of the penile urethra. Its primary role is to aid in urine passage and, in males, ejaculation.

Blood Supply

The urethral bulb receives blood through the arteries:

• Pudendal Artery: Supplies blood to the external genitalia.
• Perineal Artery: Provides additional blood flow to the perineal area.

Adequate blood supply is crucial for the normal function and healing of the urethral bulb tissues.

Nerve Supply

The pudendal nerve is the main nerve supplying the urethral bulb. It controls the sensation and motor functions, including the contraction and relaxation of muscles involved in urination and sexual activities.

Types of Urethral Bulb Disorders

Urethral bulb disorders can be classified based on their nature and underlying causes. Here are the primary types:

1. Infections:
   • Urethritis: Inflammation of the urethra.
   • Sexually Transmitted Infections (STIs): Such as chlamydia and gonorrhea affecting the urethral bulb.
2. Trauma and Injuries:
   • Physical Injury: From accidents or medical procedures.
   • Surgical Complications: Post-surgical issues affecting the urethral bulb.
3. Anatomical Abnormalities:
   • Congenital Defects: Present at birth affecting the structure.
   • Strictures: Narrowing of the urethral bulb.
4. Inflammatory Conditions:
   • Cystitis: Inflammation of the bladder extending to the urethral bulb.

5. Tumors and Cancers:
   • Benign Tumors: Non-cancerous growths.
   • Urethral Cancer: Malignant tumors affecting the urethral bulb.
6. Functional Disorders:
   • Urinary Incontinence: Loss of bladder control affecting the urethral bulb.
   • Pelvic Floor Dysfunction: Muscle issues impacting urethral bulb function.
