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] The term coarctation is another synonym, [5] but is commonly used only in the context of aortic ...
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.
Strictures are the second most common cause of chronic obstructive sialadenitis, after salivary stones. [1] In line with this, strictures may give rise to the "meal time syndrome", [ 1 ] where there is pain and swelling of the involved salivary gland upon salivary stimulation with the sight, smell and taste of food.
Ureteric stricture (ureteral stricture) is the pathological narrowing of the ureter which may lead to serious complications such as kidney failure. Pathophysiology
Indeterminate biliary strictures and suspected bile duct tumors [3] Suspected injury to bile ducts either as a result of trauma or of iatrogenic origin; Sphincter of Oddi dysfunction; Chronic pancreatitis is currently a controversial indication due to widespread availability of safer diagnostic modalities including endoscopic ultrasound, CT ...
Hydronephrosis describes hydrostatic dilation of the renal pelvis and calyces as a result of obstruction to urine flow downstream. Alternatively, hydroureter describes the dilation of the ureter, and hydronephroureter describes the dilation of the entire upper urinary tract (both the renal pelvicalyceal system and the ureter).
