The membranous urethra is a crucial part of the male urinary system. Understanding its structure, functions, and potential disorders can help in maintaining urinary health and seeking timely medical assistance when needed. This guide provides a detailed yet straightforward overview of membranous urethra disorders, including their causes, symptoms, diagnostic methods, treatments, and prevention strategies.
The urethra is a tube that carries urine from the bladder out of the body. In males, it has several parts: the prostatic, membranous, and spongy (penile) urethra. The membranous urethra is the shortest and narrowest part, passing through the pelvic floor muscles. Despite its small size, it plays a vital role in urinary control and sexual function.
Pathophysiology
Structure
- Location: Situated between the bulbous (spongy) urethra and the prostatic urethra.
- Length: Approximately 1-2 centimeters.
- Composition: Surrounded by the external urethral sphincter, a muscle that controls urine flow.
Blood Supply
- Arteries: Supplied primarily by the bulbourethral arteries, branches of the internal pudendal arteries.
- Veins: Drain into the deep dorsal vein of the penis.
Nerve Supply
- Autonomic Nerves: Provide involuntary control over the sphincter muscles.
- Somatic Nerves: Facilitate voluntary control, allowing conscious regulation of urine flow.
Understanding these aspects helps in comprehending how disorders can disrupt normal urinary functions.
Types of Membranous Urethra Disorders
Membranous urethra disorders can be categorized based on their nature and causes. Common types include:
- Urethral Stricture: Narrowing of the urethra due to scar tissue.
- Urethritis: Inflammation of the urethra, often caused by infections.

- Congenital Anomalies: Birth defects affecting the urethra’s structure.
- Urethral Diverticulum: Pouch formation in the urethral wall.
- Carcinoma: Cancerous growths in the urethral tissue.
- Fistulas: Abnormal connections between the urethra and other organs.
Each type has distinct causes, symptoms, and treatment approaches.
