Urethral Bulb Dysfunction

Urethral bulb dysfunction refers to problems with the urethral bulb, which is the expanded end of the urethra located near the prostate in men and at the vaginal end in women. This area plays a crucial role in urinary function and sexual health. Dysfunction can lead to various urinary and sexual symptoms, impacting quality of life.

Pathophysiology

Structure

The urethral bulb is a dilated portion of the urethra. In males, it lies just below the prostate gland and surrounds the membranous urethra. In females, it’s located near the vaginal opening. Its primary function is to store urine before it is expelled from the body.

Blood Supply

The urethral bulb receives blood through branches of the internal pudendal artery. Adequate blood flow is essential for normal function and healing processes.

Nerve Supply

Nerve supply to the urethral bulb comes from the pelvic plexus, involving both sympathetic and parasympathetic fibers. These nerves control the contraction and relaxation of muscles involved in urination and sexual function.
