The trigone is the area at the base of the bladder.
Trigonitis is inflammation of the urinary bladder at the trigone.
The trigone is part of the urinary bladder, not part of the kidney.

Trigone
The trigone is between the three orifices of the urinary bladder.
The trigone region is an area within the bladder, specifically located on the internal surface. It is defined by three points: the two ureteral openings and the internal urethral orifice. This triangular region is significant because it remains smooth and fixed, unlike the rest of the bladder, which can expand and contract. The trigone plays a crucial role in the urinary system by helping to signal the brain when the bladder is full.
I believe you are looking for the term "trigone".
The trigone is a smooth triangular region of the internal urinary bladder formed by the two ureteral orifices and the internal urethral orifice.The area is very sensitive to expansion and once stretched to a certain degree, the urinary bladder signals the brain of its need to empty. The signals become stronger as the bladder continues to fill.Embryologically, the trigone of the bladder is derived from the caudal end of mesonephric ducts, which is of mesodermal origin (the rest of the bladder isendodermal). In the female the mesonephric ducts regresses, causing the trigone to be less prominent, but still present.

When urine exits the urinary system, it is at the exterior of the body. There is no system "after" the urinary system.
The kidneys each have a ureter that goes to the urinary bladder. One urethra goes from the urinary bladder to the outside surface of the body. Sphincters (ring-like muscles) control the opening and closing of the urethra.
