The urethra is a crucial part of the urinary system, responsible for transporting urine from the bladder out of the body. In males, the urethra is divided into several parts, with the membranous urethra being a short segment located between the prostate and the bulbous urethra. Understanding diseases that affect this specific part is essential for diagnosing and treating urinary issues effectively.
Pathophysiology
Structure
The membranous urethra is the narrowest and least distensible part of the male urethra. It passes through the pelvic floor muscles, specifically the external urethral sphincter, which controls the flow of urine.
Blood Supply
The membranous urethra receives blood primarily from the bulbourethral arteries, which branch from the internal pudendal arteries. Adequate blood supply is vital for the tissue health and function of the urethra.
Nerve Supply
Nerve innervation is provided by the pelvic splanchnic nerves and the pudendal nerves, which play roles in controlling the sphincter muscles and sensation within the urethra.
Types of Membranous Urethra Diseases
- Urethral Stricture: Narrowing of the urethra due to scar tissue.
- Urethritis: Inflammation of the urethra, often caused by infection.
