尿道 受伤
Overview
If the urethra is injured, a person may develop urethra obstructions or strictures. 尿道 strictures occur when the urethra is injured or scarred by an infection and then narrows. As a result, problems with the normal passage of urine and semen can develop.
尿道 injuries can have devastating long-term consequences, such as potential complications of impotence, 狭窄和尿失禁.
受伤 may affect either the anterior or posterior part of the urethra. 在大多数情况下, anterior urethral trauma is characterized as a blunt injury to the perineum — the area between the 生殖器 and anus — since the urethra is located near the skin in this area. This type of trauma is often the result of straddle-like injuries, such as when a child forcefully straddles a bicycle or fence. Penetrating injuries to the anterior urethra, 比如枪伤造成的, 也可能造成狭窄或阻塞.
Posterior urethral trauma affects the part of the urethra that travels inside the body. This type of trauma almost always occurs as a result of pelvic fractures following automobile accidents, 严重跌倒或工业事故伤害.
