ABSTRACT
PURPOSE:
The AVSS with 3-D HMD is considered to provide a more realistic image and more comfortable circumstances in which the subjects are absorbed in the stimulation. We investigated the efficacy of using 3-D combined with oral medication and a stimulation (COS) test for the evaluation of vasculogenic erectile dysfunction (ED). MATERIALS ANDMETHODS:
66 patients with complaints of ED, 28 patients diagnosed with vasculogenic ED and 38 patients diagnosed with psychogenic ED were included in this study. The patients were randomly divided into the 2-D group and the 3-D group. The 2-D group patients were examined with using 2-D combined an injection and a stimulation (CIS) test. The 3-D group patients were examined with 3-D CIS test. Then a week later, the patients underwent the AVSS with 3-D HMD 1 hour after oral PDE 5 inhibitor medication. The degree of erection was monitored using the Nocturnal Electrobioimpedance Volumetric Assessment (NEVA) system.RESULTS:
On the 2-D CIS tests, 12 of 27 patients showed normal erection, and this resulted in a sensitivity and specificity of 72.7% and 56.3%, respectively. On the 3-D CIS tests, 20 of 39 patients showed normal erection and on the 3-D COS tests, 17 patients showed normal erection and this resulted in a sensitivity and specificity of 88.2% and 81.8%, and 94.1% and 72.7%, respectively. No significant difference were present in the results of the diagnosis between the 3-D CIS and 3-D COS tests.CONCLUSIONS:
Both the 3-D CIS and 3-D COS tests offer the advantage of higher sensitivity and specificity than the conventional CIS test. The 3-D COS test may be used as a substitute for the conventional CIS test due to its simplicity and less invasive nature.
