Trigonum vesicae

from Wikipedia, the free encyclopedia
The location of the trigonum vesicae

The trigone of the bladder , including bladder triangle or bladder triangle ( engl. Bladder trigone ), formerly also Lieutaud triangle called fold-free is mucosal Field (mucosa) in the bladder floor ( vesicae fundus , lat. Vesica = bubble ').

The urinary bladder triangle is located between the two ureter openings and the opening of the urethra ( ostium urethrae internum ) on the urinary bladder. It is bounded dorsally by the interureteric plica . The lower, thickened angle of the urinary bladder triangle extends as a cone, uvula vesicae, from behind into the inner urethral opening. While the mucosa of the urinary bladder in the entire bladder is loosely resting with the underlying muscles, it is taut in the area of the bladder triangle connected to the muscles to assist in urination to form a drain channel at the base of the bladder.

The trigonum vesicae is conspicuously whitish.
