Ureter(redirected from Ureteral diseases)
Also found in: Dictionary, Thesaurus, Encyclopedia.
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.
