A spongy urethra stricture is a medical condition where the spongy part of the urethra (the tube that carries urine from the bladder out of the body) becomes narrowed. This narrowing can restrict urine flow, causing various urinary problems. The spongy urethra, also known as the bulbous urethra, is located in the penis and is surrounded by erectile tissue.
Pathophysiology
Structure
The male urethra is divided into several sections:
- Prostatic Urethra: Passes through the prostate gland.
- Membranous Urethra: Travels through the pelvic floor muscles.
- Spongy (Bulbar) Urethra: Located within the penis, surrounded by spongy erectile tissue.
A stricture in the spongy urethra involves scarring and narrowing of this segment, leading to obstruction of urine flow.
Blood Supply
The spongy urethra receives blood through the bulbar arteries, which are branches of the internal pudendal artery. Adequate blood flow is essential for maintaining urethral health and function.
Nerve Supply
Nerves supplying the spongy urethra are part of the pudendal nerve plexus. These nerves control both the sensation and motor functions necessary for urination.
Types of Spongy Urethra Stricture
- Short Stricture: Limited to a small segment of the spongy urethra.
- Long Stricture: Extends over a larger length of the urethra.
- Recurrent Stricture: Stricture that returns after treatment.
- Complex Stricture: Involves multiple segments or is associated with other conditions.
Causes
- Trauma: Injury to the penis or perineum.
- Infections: Recurrent urinary tract infections.
- Instrumentation: Use of catheters or other medical instruments.
