Both men and women have a urethra, a thin tube through which urine is passed out of the body. In men, ejaculation occurs through the urethra as well. Urethral strictures are a painful condition in which scar tissue causes narrowing in the urethra, which slows or blocks the flow of urine out of the body.
A urethral stricture is a narrowing of the urethra caused by injury, instrumentation, infection, and certain non-infectious forms of urethritis. Some patients with severe urethral strictures are completely unable to urinate. This is referred to as acute urinary retention, and is a medical emergency.

None the less, the number of so called experts, past and present, is comparatively small and in broad principle their views more or less coincide. Although this review is therefore inevitably biased, it is unlikely that expert opinion will take issue with most of the general points raised here. Urethral strictures have always been common.
The stricture tissue is rich in myofibroblasts and multi-nucleated giant cells which are thought to be related to stricture formation and collagen synthesis. An increase in collagen is associated with the loss of the normal vasculature of the normal urethra. The actual incidence differs based on worldwide populations, geography, and income.
The urethra is a tube that carries urine from the bladder so it can be expelled from the body. Usually the urethra is wide enough for urine to flow freely through it. When the urethra narrows, it can restrict urinary flow. This is known as a urethral stricture.
