Q

Ischemic Priapism

A
  • low flow, veno-occlusive priapism. Painful!
    • Decreased venous outflow = increased pressure = decreased arterial inflow
    • Emergency!!! Can lead to fibrosis and ED

Q

Non-ischemic Priapism

A
  • high flow, arterial
    • Increased arterial inflow without reduced venous outflow
    • High inflow + high outflow
    • Prolonged, non-painful partially rigid erection
    • Non emergent – usually will resolve on it’s own

Q

Q

Peyronie’s Disease characteristics

A
  • An inflammatory process occurs which results in a fibrous plaque developing on the penis, usually on the dorsum, which in turn causes an curvature of the penis.
