ureter
ureter , thick-walled tube that conveys urine from the kidney to the urinary bladder. It is approximately 10 in. (25.4 cm) long, with the upper half located in the abdomen and the lower half in the pelvic region. Urine is transported down this tube under the impetus of gravity assisted by contractions of the smooth muscles that line the ureteral walls. A blocked ureter can result from congenital abnormality, a tumor, or the formation of kidney stones. Blockage may require surgery to prevent loss of urinary function and eventual urea poisoning. See urinary system . |

ureter
ureter The tube of smooth muscle which carries urine from the kidney to the bladder. The ureter starts as the outlet from the ‘pelvis’ in the centre of the kidney — the receptacle for the urine leaving thousands of microscopic tubules. The two ureters enter the upper part of the bladder symmetrically on the two sides. Between them, they deliver urine on average at a rate of about 1 ml min. The ureters can be a source of pain (colic) if kidney stones fragment and pass down them.
Stuart Judge See kidneys; urogenital system. |
