It is also sometimes called a stricture (as in urethral stricture). [ 3 ] Stricture 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 ).

Rectal strictures are more common in Crohn's disease than in ulcerative colitis. [2] There is a risk of malignancy developing at the site of stricture; therefore, tissue biopsy of strictures is carried out in order to check for dysplasia or malignancy.
The protection provided by the foreskin for the glans penis and meatus has been recognized since 1915. In the absence of the foreskin the meatus is exposed to mechanical and chemical irritation from ammoniacal diaper (nappy) that produces blister formation and ulceration of the urethral opening, which eventually gives rise to meatal stenosis (a narrowing of the opening).

[1] Urethral stricture is caused by injury, instrumentation, infection, and certain non-infectious forms of urethritis. The ...
Treatment of ureteric strictures varies from one patient to another depending on the level, cause and extent of stricture in addition to patient factors such as comorbidities and preferences. Treatment options include minimally invasive palliative procedures such as Nephrostomy tube insertion or ureteric stents insertion or ureteral balloon ...
Many leading urologists in the United States consider urethrotomy to be (almost) totally ineffective at providing long-term resolution of urethral stricture disease, and advocate excision of the damaged area followed by either a surgical anastomosis of the (now) patent urethral ends, or a grafting of similar tissue harvested from elsewhere on ...
Laryngotracheal stenosis is an umbrella term for a wide and heterogeneous group of very rare conditions. The population incidence of adult post-intubation laryngotracheal stenosis which is the commonest benign sub-type of this condition is approximately 1 in 200,000 adults per year. [10]
