The urethra is the tube that carries urine from the bladder to the outside of the body. The spongy urethra is the part of the urethra that runs through the penis in males. Obstruction in this region can lead to difficulty in urinating, discomfort, and other serious health complications.
Pathophysiology of Spongy Urethra Obstruction
- Structure: The spongy urethra is located in the penis, surrounded by a spongy tissue (hence the name). It is the longest part of the urethra, extending from the bulbar urethra to the external urethral orifice at the tip of the penis.
- Blood Supply: The blood supply to the spongy urethra comes from the internal pudendal artery, which branches from the internal iliac artery. This ensures that the urethra has the necessary oxygen and nutrients for proper functioning.
- Nerve Supply: The urethra is innervated by the pudendal nerve, which controls the muscles surrounding the urethra for proper bladder control.
- Obstruction Mechanism: Obstruction in the spongy urethra can occur due to various reasons, such as scarring (stricture), infection, or physical trauma, preventing normal urine flow.
Types of Spongy Urethra Obstruction
- Acquired Obstruction: Caused by factors such as infections, injuries, or surgery complications.
- Congenital Obstruction: Present at birth due to abnormal development of the urethra.
- Benign Obstruction: Often due to scarring or non-cancerous conditions.
- Malignant Obstruction: Caused by cancerous growths in or around the urethra.
- Functional Obstruction: Occurs when the urethra’s muscles do not function properly, leading to impaired urination.
Causes of Spongy Urethra Obstruction
