Urethral bulb injury refers to damage to the bulbous part of the urethra, which is the lower part of the urinary tube located in the perineum (the area between the scrotum and anus in males). This injury can result from various causes and may lead to significant urinary and sexual dysfunction if not properly treated.
The urethral bulb is the widened, spongy part of the male urethra located near the perineum. Injury to this area can result from trauma, medical procedures, infections, or other causes, leading to complications like strictures (narrowing), fistulas (abnormal connections), and urinary retention.
Pathophysiology
Structure
- Urethral Bulb: Part of the spongy urethra, surrounded by erectile tissue.
- Function: Facilitates urine flow from the bladder to the outside of the body.
Blood Supply
- Arterial Supply: Primarily from the bulbourethral arteries.

Nerve Supply
- Nerves: Supplied by the pudendal nerve.
- Function: Controls muscle movements and sensation in the area.
