AB029. The clinical significance of RigiScan plus detection

Abstract: Erectile dysfunction (ED) is a common disease in male outpatient service, the penis hardness testing of ED in the clinical diagnosis has important significance, past some detection methods, such as nocturnal penile tumescence monitoring (NPT) due to time-consuming is not easy in outpatient service and a vasodilator agent intervention tests such as color Doppler detection due to the injection of drugs in the penis is difficult for patients to accept. In 1965 night rapid eye movement sleep phase 3–5 times of penile erection phenomenon was first reported by Fisher, in 1970 the night monitoring instrument of penis erectile hardness is used for evaluation of male erectile function. In 1985 researchers reported the RigiScan plus software was used to record of nocturnal erection, 1994 this method was gradually improved and used in clinical application by Levine. Sol reported that after taking sildenafil the patient was given audio-visual stimulation to induce the penis erects, then the RigiScan plus was used to record erection hardness in 2006. Due to the complexity of the etiology of ED, for the evaluation of penile erectile function should also be in many ways any single check has its limitations, the drug combined with audio-visual sense stimulation induced penile erection hardness monitoring (AVSS + RigiScan plus) in newly diagnosed patients with erectile function has a certain significance. Compared with AVSS + RigiScan examination, NPT is more expensive, time-consuming, and cumbersome, and patients feel unwell. And AVSS + RigiScan is simple, effective, easy, cheap, and the diagnostic accuracy rate matching to NPT, it is suitable for routine examination of patients with newly diagnosed ED.
