Various criteria described for normal have been based on either blood flow velocity alone or the combination of blood flow velocity and arterial dilatation of each cavernous artery. Unfortunately, less than 20% of impotent men have classical arterial anatomy and the aforementioned normal criteria do not take into account the various possible anatomical and acquired anomalies that can exist. In addition, the multiplicity of parameters used to describe normal are cumbersome to use for patient comparison and statistical analysis. In this study, 4 indexes were developed to express the results of a duplex ultrasound penile blood flow study and they were tested in an impotent population comprised of 75 men with arterial disease and 33 men with impotence due to neurogenic or psychogenic causes. A significant difference was observed between these 2 groups using all 4 indexes (p <0.001). However, the penile blood flow index, which incorporated velocity and dilatation, performed best as determined by sensitivity, specificity and receiver operating characteristics. Based on the results of this study, the penile blood flow index, which represents the summation of the percentage of dilatation and peak blood flow velocity of each cavernous artery, provides an accurate reflection of total penile blood flow as measured by duplex ultrasound. © 1991 by The American Urological Association Education and Research, Inc.FiguresReferencesRelatedDetailsCited ByMartins F and Padma-Nathan H (2018) Diffuse Veno-Occlusive Dysfunction: The Underlying Hemodynamic Abnormality Resulting in Failure to Respond to Intracavernous PharmacotherapyJournal of Urology, VOL. 156, NO. 6, (1942-1946), Online publication date: 1-Dec-1996.Jarow J and DeFranzo A (2018) Long-Term Results of Arterial Bypass Surgery for Impotence Secondary to Segmental Vascular DiseaseJournal of Urology, VOL. 156, NO. 3, (982-985), Online publication date: 1-Sep-1996.Dean Knoll L, Benson R, Bilhartz D, Minich P and Furlow W (2018) A Randomized Crossover Study Using Yohimbine and Isoxsuprine Versus Pentoxifylline in the Management of Vasculogenic ImpotenceJournal of Urology, VOL. 155, NO. 1, (144-146), Online publication date: 1-Jan-1996.Wegner H, Andresen R, Knispel H, Banzer D and Miller K (2018) Evaluation of Penile Arteries with Color-Coded Duplex Sonography: Prevalence and Possible Therapeutic Implications of Connections Between Dorsal and Cavernous Arteries in Impotent MenJournal of Urology, VOL. 153, NO. 5, (1469-1471), Online publication date: 1-May-1995.Rhee E, Osborn A and Witt M (2018) The Correlation of Cavernous Systolic Occlusion Pressure With Peak Velocity Flow Using Color Duplex Doppler UltrasoundJournal of Urology, VOL. 153, NO. 2, (358-360), Online publication date: 1-Feb-1995.Bare R, DeFranzo A and Jarow J (2018) Intraoperative Arteriography Facilitates Penile RevascularizationJournal of Urology, VOL. 151, NO. 4, (1019-1021), Online publication date: 1-Apr-1994.Lopez J and Jarow J (2018) Penile Vascular Evaluation of Men with Peyronie’s DiseaseJournal of Urology, VOL. 149, NO. 1, (53-55), Online publication date: 1-Jan-1993.Knispel H and Andresen R (2018) Evaluation of Vasculogenic Impotence by Monitoring of Cavernous Oxygen TensionJournal of Urology, VOL. 149, NO. 5 Part 2, (1276-1279), Online publication date: 1-May-1993.von Heyden B, Donatucci C, Kaula N and Lue T (2018) Intracavernous Pharmacotherapy for Impotence: Selection of Appropriate Agent and DoseJournal of Urology, VOL. 149, NO. 5 Part 2, (1288-1290), Online publication date: 1-May-1993.
