The urethra is a vital part of the urinary and reproductive systems. It is a tube that carries urine from the bladder to the outside of the body. The spongy urethra, also known as the penile urethra, is a section of the urethra that passes through the penis. It plays an essential role in both urination and ejaculation. When problems arise in the spongy urethra, it can lead to discomfort and complications.
This guide will provide a detailed explanation of the diseases of the spongy urethra, including definitions, causes, symptoms, diagnosis, treatments, and preventive measures.
Pathophysiology of the Spongy Urethra
Structure
The spongy urethra is the longest section of the male urethra, measuring around 15-20 cm in length. It is located within the penis and is surrounded by erectile tissue called the corpus spongiosum. This tissue helps protect the urethra during erections.
The spongy urethra is responsible for transporting both urine and semen. Its structure is different from the rest of the urethra due to its location in the penis and its surrounding spongy tissue.
Blood Supply
The blood supply to the spongy urethra comes from the internal pudendal artery. The artery provides oxygen and nutrients to the tissues surrounding the urethra, ensuring proper function and health.
Nerve Supply
The nerves that supply the spongy urethra are primarily branches from the pudendal nerve. This nerve is responsible for sensation and motor control in the lower parts of the body, including the urethra.
Types of Spongy Urethra Diseases
Spongy urethra diseases are conditions that affect the function and health of the spongy urethra. These diseases can vary in severity, from mild irritations to life-threatening infections. Some of the most common types include:
- Urethritis – Inflammation of the urethra caused by infections or injuries.
- Stricture – A narrowing of the urethra that can make urination difficult.
- Infections (Bacterial, Viral, Fungal) – Various microorganisms can cause infections in the spongy urethra.
- Trauma or Injury – Accidental injury to the penis or urethra that disrupts normal function.
