Can the vacuum test be used as a diagnostic method for determining the degree of severity of erectile dysfunction?
We performed the vacuum test (VT) using the Osbon Erec Aid System on 224 patients with erectile dysfunction (ED). The age range was 26-78 years. The vacuum procedure was performed three times at intervals of 2-8 days, using the negative pressure device (NPD). Negative pressure was created for 3-5 minutes, followed by the removal of the cylinder; the tension ring was left in place for an additional 1-2 minutes. During each procedure, we observed color and temperature changes in the glans penis and changes in the tumescence and maximal rigidity of the penis (MRP); dynamic changes in MRP were noted again 1-2 minutes after the procedure. For comparison and verification, we carried out parallel tests: nocturnal penile tumescence (NPT), penile brachial index (PBI), and Doppler penile ultrasound (DPU). On completion of the investigation, we found that 10.3% had mild ED, 38.5% moderate ED, and 41.5% severe ED. The parallel tests confirmed the diagnosis reached by VT. Thus, changes after vacuum procedures together with local symptoms can serve as criteria for determining the degree of severity of ED.
