- An abnormal narrowing of a body passage, especially a tube or a canal. The stricture may be due, for example, to scar tissue or to a tumor. Stricture refers to both the process of narrowing and the narrowed part itself. A stricture is also anything that closely restrains or limits. Shakespeare used "stricture" in the sense of strictness, as in "A man of stricture and firm abstinence."

* * *n.a narrowing of any tubular structure in the body, such as the oesophagus (gullet), bowel, ureter, or urethra. A stricture may result from inflammation, muscular spasm, growth of a tumour within the affected part, or from pressure on it by neighbouring organs. For example, a urethral stricture is a fibrous narrowing of the urethra, usually resulting from injury or inflammation. The patient has increasing difficulty in passing urine and may develop retention. The site and length of the stricture is assessed by urethrography and urethroscopy, and treatment is by periodic dilatation of the urethra using sound, urethrotomy, or urethroplasty. Strictures in the alimentary canal are dilated by balloon or stricturoplasty.
