Vacuum Suction Device

The VSD is essentially a cylindrical pump (battery or manually operated), which encloses the penis. When activated, air is sucked out of the sealed chamber, creating a vacuum. Blood is then drawn to the penis thanks to the vacuuming effect. A firm rubber ring is then placed at the base of the penis to trap the blood in the erectile chambers, keeping the penis firm.

The VSD has the following disadvantages:

• It may take 10 minutes to operate and it is cumbersome.
• The erection achieved is usually not a complete one.
• The rubber ring can cause discomfort and obstruct the process of ejaculation.

In patients with advanced Erectile Dysfunction unresponsive to ICP and surgical implant of a penile prothesis is not an option, the use of VSD may remain the only option. In our experience, it is otherwise best to use VSD as an adjunctive therapy to ICP to help maintain the blood flow.
