Century Dictionary and Cyclopedia
    • n ureter The excretory duct of the kidney; a tube conveying the renal excretion (urine) to the bladder, when that structure exists, as in mammals, or into the cloaca, in case no bladder exists—in any case, into the lower part of the allantoic cavity of the fetus, however modified in adult life. See cut under kidney. In man the ureter is a very slender tube, from 15 to 18 inches long, running from the pelvis of the kidney to the base of the bladder, at the posterior angle of the trigonum. It rests chiefly upon the psoas muscle, behind the peritoneum. Its structure includes a fibrous coat, longitudinal and circular muscular fibers, and a lining of mucous membrane, with vessels and nerves from various sources. The ureter pierces the wall of the bladder very obliquely, running for nearly an inch between the muscular and mucous coats of that viscus.
