The trigone is a triangular area located at the base of the urinary bladder. It is bounded by the two ureteral openings (where urine enters the bladder from the kidneys) and the internal urethral orifice (where urine exits the bladder into the urethra). Unlike the rest of the bladder lining, the trigone has a smooth texture and is less elastic. Its primary function is to help control the flow of urine, ensuring it moves efficiently from the bladder to the urethra.
A stricture refers to the narrowing of a bodily passage due to scar tissue formation. When a stricture occurs in the trigone of the urinary bladder, it can lead to significant urinary problems. This condition may obstruct urine flow, causing discomfort, urinary retention, and increasing the risk of urinary tract infections (UTIs).
Pathophysiology of Trigone Stricture
Structure
The trigone is composed of three smooth muscles and a specialized lining that is different from the rest of the bladder. This unique structure makes it less prone to involuntary contractions, allowing precise control over urine flow.
Blood Supply
The trigone receives its blood supply primarily from the superior and inferior vesical arteries, which branch from the internal iliac arteries. Adequate blood flow is crucial for maintaining the health of the bladder tissues and facilitating healing processes.
Nerve Supply
The trigone is innervated by the autonomic nervous system, specifically the pelvic splanchnic nerves (parasympathetic) and the hypogastric nerves (sympathetic). These nerves control bladder contractions and relaxation, playing a vital role in the micturition (urination) process.
Types of Trigone Strictures
Strictures in the trigone can be classified based on their cause, location, and severity:
- Congenital Strictures: Present from birth due to developmental anomalies.
- Acquired Strictures: Develop later in life, often due to injury or disease.
- Primary Strictures: Result from direct damage to the bladder or trigone area.
- Secondary Strictures: Develop as a complication of other medical conditions or treatments.
Causes of Trigone Stricture
Strictures in the trigone can arise from various factors. Here are 20 potential causes:
