A stenosis (/stÉËnoÊsÉ¨s/ ; plural: stenoses, /stÉËnoÊËsiËz/) (from Ancient Greek ÏÏÎ­Î½ÏÏÎ¹Ï, narrowing) is an abnormal narrowing in a blood vessel or other tubular organ or structure. It is also sometimes called a stricture (as in urethral stricture).tricture as a term is usually used when narrowing is caused by contraction of smooth muscle (e.g., achalasia, prinzmetal angina); stenosis is usually used when narrowing is caused by lesion that reduces the space of lumen (e.g., atherosclerosis).
