The urinary bladder is a vital organ in the human body responsible for storing and expelling urine. A small but significant area within the bladder is the trigone. Understanding the trigone’s structure, function, and related diseases is essential for recognizing urinary health issues. This guide provides an in-depth look at the trigone of the urinary bladder, its diseases, pathophysiology, causes, symptoms, diagnostic tests, treatments, prevention, and frequently asked questions. Written in simple language, this article aims to enhance readability and accessibility for everyone.
The trigone is a triangular region located at the base of the urinary bladder. Unlike the rest of the bladder lining, the trigone has a smooth, fixed structure with three points:
- Two ureteric orifices: Where the ureters enter the bladder from the kidneys.
- One internal urethral orifice: Where urine exits the bladder into the urethra.
Importance of the Trigone
- Sensory Role: The trigone contains a high concentration of nerve endings that signal the brain when the bladder is full, initiating the urge to urinate.
- Structural Stability: Its fixed position helps maintain the bladder’s shape and prevents it from collapsing.
Pathophysiology of the Trigone
Structure
The trigone is composed of smooth muscle tissue, similar to the rest of the bladder wall. However, its three fixed points provide stability and prevent the bladder from changing shape significantly during filling and emptying.
Blood Supply
- Arteries: The bladder, including the trigone, receives blood primarily from the superior and inferior vesical arteries.
- Veins: Blood is drained through the vesical veins, which accompany the arteries.
Nerve Supply
- Autonomic Nervous System: The trigone is innervated by the pelvic splanchnic nerves (parasympathetic) and the hypogastric nerves (sympathetic).
- Sensory Nerves: High density of sensory nerves in the trigone helps in detecting bladder fullness and initiating the micturition reflex.

Several conditions can impact the trigone, leading to urinary issues. Below are common diseases related to the trigone:
- Bladder Infections (Cystitis)
- Bladder Stones (Cystolithiasis)
