Membranous urethra infection is a medical condition affecting the membranous part of the urethra—the narrowest section of the male urethra located between the prostate and the bulbous urethra. Understanding this condition involves exploring its causes, symptoms, diagnostic methods, treatments, and preventive measures. This guide provides detailed information in simple language to help you recognize, understand, and seek appropriate care for membranous urethra infections.
The membranous urethra is a short segment of the urethra that passes through the pelvic floor muscles. Infections in this area are less common compared to other parts of the urethra but can lead to significant discomfort and complications if not treated promptly. These infections can result from bacteria, viruses, or other pathogens entering the urinary tract.
Pathophysiology
Structure
The urethra is divided into several parts:
- Prostatic Urethra: Passes through the prostate gland.
- Membranous Urethra: The narrowest part, located between the prostate and bulbous urethra.
- Bulbous Urethra: Surrounds the bulb of the penis.
- Spongy (Penile) Urethra: Runs through the penis to the external opening.
Blood Supply
The membranous urethra receives blood through the bulbourethral arteries, which branch from the internal pudendal arteries. Adequate blood flow is essential for tissue health and immune response.
Nerve Supply
Nerve fibers from the pudendal nerve supply the membranous urethra, controlling sensations and muscle contractions necessary for urination.
Types of Membranous Urethra Infections
- Bacterial Urethritis: Caused by bacteria like Escherichia coli.
- Viral Urethritis: Caused by viruses such as herpes simplex virus.
- Fungal Urethritis: Caused by fungi like Candida species.
- Sexually Transmitted Infections (STIs): Including gonorrhea and chlamydia.
- Non-Infectious Urethritis: Caused by irritants or trauma.
