Abstract
Vacuum erection devices are an acceptable alternative for the management of erectile dysfunction. The safety of such devices has been questioned because of their effects on penile blood flow. We report the use of Doppler ultrasonography to assess arterial flow and its value in ensuring long-term safety of a new external vacuum device. Sixteen patients were studied. At 3 months it was possible to confirm the efficacy and safety of the method and model in 14 patients, 12 of whom had a significant improvement in their sexual function. By 10 months, only 6 were continuing to use the device. Doppler sonography appears to be an effective technique for assessing penile blood flow during restriction from a vacuum device. The new vacuum device provides a satisfactory short-term alternative to other more invasive forms of therapy.
