| Popis: | Erections are inhibited by sympathetic stimulation. Anxiety or psychologic inhibition may produce abnormal response during impotence workup. The use of intracorporeal alpha blockers (phentolamine) and audiovisual sexual stimulation (AVSS) has been used to decrease sympathetic outflow and enhance erectile response. Thirty-three patients with suspected vasculogenic impotence were studied. They underwent pulsed Doppler ultrasound (PDUS) with multiple doses of tri-mix (mix of papaverine, phentolamine, and prostaglandin E1). AVSS was applied after maximal response to tri-mix. Seventeen patients (51.5%) responded to multidose with grade IV or V erection. When AVSS was started, 5 more patients responded, and 7 upgraded to grade V with overall response of 40 percent. AVSS can augment the in-office response to pharmacologic testing above that obtained by "maximal" pharmacologic dosing, thereby increasing the sensitivity and specificity of the test. |
