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 ). [ 4 ]
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.
A urethral stricture is a narrowing of the urethra, the tube connected to the bladder that allows urination. The narrowing reduces the flow of urine and makes it more difficult or even painful to empty the bladder. [1] Urethral stricture is caused by injury, instrumentation, infection, and certain non-infectious forms of urethritis. The ...
In order to open the stricture, a surgeon can insert a bougie – a weighted tube used to dilate the constricted areas in the esophagus. [3] It can sometimes be treated with other medications. For example, an H2 antagonist (e.g. ranitidine) or a proton-pump inhibitor (e.g. omeprazole) can treat underlying acid reflux disease.

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 ...
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]
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).
