ureter

 [u-re´ter]
the fibromuscular tube, 41 to 46 cm long, through which the urine passes from the kidney to the bladder. adj., adj ure´teral, ureter´ic. As urine is produced by each kidney, it passes into the ureter, which, by contracting rhythmically, forces the urine along and empties it in spurts into the bladder. After being stored temporarily in the bladder, the urine passes out of the body by way of the urethra. Occasionally a small calculus or stone forms in a kidney and passes into a ureter, obstructing it. (See kidney stone.)

u·re·ter

(yū-rē'tĕr, yū'rē-ter), [TA] Although the classically correct pronunciation stresses the second-last syllable of this word (ure'ter), the first syllable is often stressed in the U.S. (ur'eter). Do not confuse this word and its derivatives with urethra and its derivatives.
The tube that conducts the urine from the renal pelvis to the bladder; consists of abdominal and pelvic parts; lined with transitional epithelium surrounded by smooth muscle, both circular and longitudinal, and covered externally by an adventitia.
[G. ourētēr, urinary canal]

ureter

[yoo͡r′ətər, yoo͡rē′tər]
Etymology: Gk, oureter
one of a pair of tubes, about 30 cm long, that carries urine from the kidney into the bladder. Each tube is composed of a fibrous, a muscular, and a mucous coat and divides into an abdominal part and a pelvic part. The abdominal part lies behind the peritoneum on the medial side of the psoas major and enters the pelvic cavity by crossing either the termination of the common iliac artery or the commencement of the external iliac artery. In men the pelvic part of the ureter runs caudally along the lateral wall of the pelvic cavity and reaches the lateral angle of the bladder just ventral to the upper tip of the seminal vesicle. In women the pelvic part of the ureter forms the posterior boundary of the ovarian fossa and runs medially and ventrally along the upper part of the vagina. The ureter enters the bladder through a tunnel that functions as a valve to prevent backflow of urine into the ureter when the bladder contracts. Connecting with the kidneys, the ureters expand into funnel-shaped renal pelves that branch into calyces. Urine is pumped through the ureters by peristaltic waves that occur an average of three times a minute. ureteral, adj.

ureter

A tube that carries urine downwards from each kidney to the urinary bladder for temporary storage. The ureters have muscular walls that can contract to assist in the propulsion of the urine.

ureter

the duct that carries URINE from the kidney to the CLOACA or urinary BLADDER.

Ureter

The tube that carries urine from the kidney to the bladder, with each kidney having one ureter.

ureter

the fibromuscular tube through which the urine passes from the kidney to the bladder.

ectopic ureter
an abnormally placed opening of the ureter, either into the urinary bladder or at another site in the lower urinary or genital tract. There is usually constant dribbling of urine and commonly an associated pyuria.
