The constriction of urethra is usually due to tissue inflammation or a presence of scar tissue. There can be many factors that result in scar tissue. Young boys who have gone through hypospadias surgery (a method to correct an underdeveloped urethra) and men who have penile implants have a higher chance of developing urethral stricture.
The tube that carries urine out of the body is known as urethra. For men, this thin tube is responsible for ejaculation. Narrowing of this urethral tube is known as Urethral Stricture Disease. The narrowing can happen due to scars, injury or infection that blocks or slows the flow of urine in this tube.
The delay in treatment of AVN may worsen the condition with time. In case of untreated condition, sooner or later, the bone may also collapse. Avascular Necrosis may result in bone to suffer the loss of its smooth shape, with a tendency of severe arthritis. Avascular Necrosis (AVN) might not show any symptoms in the early stages; however, as time passes, the affected joint starts to feel the hurt as some weight is put on it, eventually also when lying down. Pain is usually gradually developed and may be mild or severe.
Cartilage tissue is a great shock absorber. Sport-specific activities like running, jumping, and climbing can happen with ease because of Hyaline cartilage that is present in various joints. These high impact actions can also lead to accidental injuries.
