The urinary bladder is a vital organ in the urinary system, responsible for storing urine before it is expelled from the body. Within the bladder lies a specialized triangular area known as the trigone. Injuries to the trigone can lead to significant urinary issues and complications. This guide provides an in-depth look at trigone injuries, covering definitions, pathophysiology, types, causes, symptoms, diagnostic methods, treatments, prevention strategies, and frequently asked questions.
Trigone of the Urinary Bladder:
- Location: The trigone is a smooth, triangular region at the base of the bladder, bordered by the two ureteric orifices (where the ureters enter the bladder) and the internal urethral orifice (where urine exits the bladder into the urethra).
- Function: Unlike the rest of the bladder, the trigone lacks rugae (folds) and is less distensible. It plays a crucial role in maintaining the proper function and position of the bladder and urethra.
Trigone Injury:
- Definition: Damage or trauma to the trigone area can disrupt normal urinary function, potentially leading to urinary retention, incontinence, infections, and other complications.
Pathophysiology
Structure:
- The trigone is composed of three smooth areas: two ureteric orifices and one internal urethral orifice.
- It is composed of specialized transitional epithelium that is less stretchy compared to the rest of the bladder.
Blood Supply:
- Primarily supplied by the superior and inferior vesical arteries, branches of the internal iliac arteries.
- Rich vascular supply ensures efficient healing but also means that injuries can lead to significant bleeding.
Nerve Supply:
- Innervated by the autonomic nervous system, including both sympathetic and parasympathetic fibers.
- Controls bladder contractions and relaxation during urination.
Injury Mechanism:
- Traumatic events (e.g., accidents, surgical complications) can cause direct damage.
- Infections or inflammatory conditions can lead to scarring and dysfunction.
Types of Trigone Injuries

- Caused by blunt or penetrating trauma.
- Iatrogenic Injury:
- Resulting from medical procedures or surgeries.
