The prostate is a small gland in men that helps produce semen. It’s divided into different areas called zones. The Central Zone is one of these areas. A stricture refers to a narrowing or tightening of a part of the body. Therefore, a Prostate Central Zone Stricture means there’s a narrowing in the central part of the prostate gland. This can affect how urine flows through the urethra, leading to various urinary problems.
Pathophysiology
Understanding how the prostate and its central zone work helps in comprehending strictures.
Structure
- Prostate Gland: Located below the bladder, surrounds the urethra.
- Zones:
- Peripheral Zone: Largest part, near the rectum.
- Central Zone: Surrounds ejaculatory ducts, less prone to cancer.
- Transitional Zone: Surrounds the urethra, often affected in BPH.
Blood Supply
- Arteries: Prostate receives blood mainly from the superior and inferior vesical arteries.
- Veins: Drain into the prostatic plexus and then to the internal iliac veins.
Nerve Supply
- Autonomic Nerves: Control involuntary functions like urine flow.
- Somatic Nerves: Manage voluntary actions, such as muscle control during urination.
Types of Central Zone Strictures
Strictures can vary based on their cause and location within the central zone.
- Idiopathic Stricture: No known cause.
- Post-Surgical Stricture: Develops after prostate surgery.
- Traumatic Stricture: Resulting from injury.
- Inflammatory Stricture: Due to infections or prostatitis.
Causes
Numerous factors can lead to a central zone stricture:
- Prostatitis: Inflammation of the prostate.
- Urinary Tract Infections (UTIs)
- Trauma or Injury
- Prostate Surgery: Such as TURP.
- Radiation Therapy
