External vacuum devices are being used increasingly for the management of erectile dysfunction. There is limited information regarding the effect of vacuum devices on penile blood flow and potential for ischemic penile injury. The penile xenon washout rate was measured before and after application of 2 vacuum systems in 15 subjects. Compared to flaccid state measurements the xenon washout rate did not change significantly with the Synergist Erection System but it was significantly reduced with the Osbon ErecAid System. However, the degree and duration of decrease in penile blood flow that may result in ischemic changes are unknown.
外部真空装置越来越多地用于治疗勃起功能障碍。关于真空装置对阴茎血流的影响以及阴茎缺血性损伤可能性的信息有限。在15名受试者中，测量了应用两种真空系统前后的阴茎氙清除率。与疲软状态测量结果相比，使用协同勃起系统时氙清除率没有显著变化，但使用奥森勃起辅助系统时氙清除率显著降低。然而，可能导致缺血性改变的阴茎血流减少程度和持续时间尚不清楚。
