What is the Trigone?

There is a triangular area, called the trigone, formed by three openings in the floor of the urinary bladder. … The third opening, at the apex of the trigone, is the opening into the urethra. A band of the detrusor muscle encircles this opening to form the internal urethral sphincter.

Is the Trigone a muscle?

The upper and lower urinary tract compartments form independently, connecting at mid-gestation when the ureters move from their primary insertion site in the Wolffian ducts to the trigone, a muscular structure comprising the bladder floor just above the urethra.

Hydronephrosis can occur in one or both kidneys. The main function of the urinary tract is to remove wastes and fluid from the body.

Why is the Trigone important?

Precise connections between ureters and the trigone are crucial for function of the valve mechanism that prevents back flow of urine from the bladder to the ureters, a major cause of reflux and obstruction, which can damage the kidney and cause severe health problems including end-stage renal disease.
