Treatment of high-flow priapism

High-flow priapism usually isn’t an emergency because blood is still flowing through the penis. However, only a doctor can tell whether your priapism is low-flow or high-flow.

If you think you have priapism, contact a doctor immediately. Avoid trying any treatments at home, as they could make things worse.

Important: If you have heart problems, tell your doctor before starting any treatment.

Treatment options depend on the type and how long the priapism has lasted. For high-flow priapism, the goal is to reduce the extra blood flowing into the penis.

The first steps may include:

• Observation: The doctor may simply monitor the condition for a while, as high-flow priapism can sometimes improve on its own. In some adults, medicines may be used to reduce erections during sleep while the injured blood vessel heals.
• Ice or gentle pressure: Your doctor may recommend an ice pack or gentle pressure on the injured area (between the scrotum and anus) to help reduce swelling.

If these measures don’t work, other treatments may be considered:

• Artery embolisation: A procedure that blocks the damaged blood vessel causing the extra blood flow. The doctor usually uses a material that can be temporary, which helps reduce the risk of affecting future erections. The procedure can be repeated if needed.
• Surgical ligation (rarely needed): An operation to close the damaged blood vessel. It is usually only considered if embolisation does not work. Because this surgery can damage the blood supply needed for erections, it is used only in selected cases.
