A urinary bladder stricture refers to a narrowing of the bladder neck or urethra, which can impede the normal flow of urine. This condition can lead to various urinary symptoms and may affect both men and women, although it is more common in men. Understanding bladder strictures involves exploring their causes, symptoms, diagnostic methods, treatment options, and preventive measures. This guide provides a detailed yet straightforward overview to help you recognize and manage urinary bladder strictures effectively.
A urinary bladder stricture is a condition where the bladder neck or urethra becomes narrowed due to scar tissue formation. This narrowing restricts the passage of urine from the bladder out through the urethra, leading to difficulty in urination and other related symptoms.
Key Definitions:
- Bladder Neck: The area where the bladder connects to the urethra.
- Urethra: The tube that carries urine from the bladder out of the body.
- Stricture: An abnormal narrowing of a bodily passage.
Pathophysiology
Structure of the Urinary System
The urinary system includes the kidneys, ureters, bladder, and urethra. The bladder stores urine until it is expelled from the body through the urethra.
Blood Supply
The bladder receives blood from the superior and inferior vesical arteries, which branch from the internal iliac arteries. Adequate blood flow is essential for the bladder’s function and healing processes.
Nerve Supply
The bladder is innervated by the autonomic nervous system, including the pelvic nerves and the hypogastric plexus. These nerves control bladder contractions and the relaxation of the urethral sphincters during urination.
Development of Strictures
Strictures develop when scar tissue forms in the bladder neck or urethra, often as a result of injury, infection, or inflammation. This scar tissue replaces normal tissue, leading to a narrowed passage that obstructs urine flow.
Types of Urinary Bladder Strictures
- Urethral Stricture: Narrowing of the urethra, more common in men.
- Bladder Neck Stricture: Narrowing at the bladder’s exit point.
- Posterior Urethral Stricture: Located near the base of the penis.
- Bulbar Urethral Stricture: Located in the part of the urethra within the bulb of the penis.
- Membranous Urethral Stricture: Located between the bulbous and prostatic urethra.
Causes of Urinary Bladder Stricture
Urinary bladder strictures can result from various factors, including:
- Injury or Trauma: Accidents or surgical procedures can damage the urethra or bladder neck.
- Infections: Chronic urinary infections can lead to scarring.
- Inflammatory Diseases: Conditions like lichen sclerosus.
- Previous Urethral Surgery: Surgeries like prostatectomy may cause scarring.
- Prolonged Catheter Use: Long-term use of urinary catheters increases the risk.
