Abstract
Objective: Our objective was to develop a single parameter that will adequately express the results of color duplex Doppler ultrasonography penile arterial blood flow studies.
Material and methods: We have studied 124 impotent patients with a mean age of 47 years (19-75, SD 13.71). Diameters of cavernosal arteries were measured using duplex Doppler ultrasound. Peak systolic velocities (PSV) zere also evaluated. After the initial ultrasound, papaverine-HCl was injected into the corpora cavernosa. The arterial diameters of both cavernosal arteries, PSV and end diastolic velocity (EDV) of cavernosal arteries zere measured aga/'n. Following these measurements, Penile blood flow index (PBFI) was calculated. Statistical analysis using linear discrimination, correlation coeffcients and Student-t test was performed. Results: According to Doppler ultrasonographic parameters, 44 out of 124 patients were classifed as arteriogenic impotent and 80 as non-impotent. Screening tests were performed for PBFI and values which were greater than 210 were accepted as normal arterial vascularity and values less than 210 were accepted as arterial failure (p
