1984年10月から1986年9月までの2年間に関西性科学研究所を受診したIMP患者の中から無差別に選んだ555例にPBI検査を施行した.low PBI (0.6以下)を示したものは29例であった.このうち13例に陰茎の血行障害をきたす可能性のあるrisk factorが見出されたPBI was measured in 555 patients chosen at random from those who visited our impotence clinic between October 1984 and September 1986. Of 555 patients with impotence 29 (5.2%) showed a low PBI level of less than 0.6. On the basis of carefully taken history, risk factors causing the disturbance of penile blood flow were found in 13 (44.8%) of these 29 patients. They included diabetes mellitus, hypertension, surgery of pelvic organ, vertebral injury, vascular disorder of brain and gangliosympathectomy. Although penile angiography is necessary to make the definite diagnosis of vasculogenic impotence, hospitalization is usually required to perform the examination. Measurement of PBI is useful as a screening test to detect vasculogenic impotence at an outpatient clinic, because this examination is noninvasive and technically easy.
