The technique is based on the simultaneous recording of the change in blood volume and venous outflow in the flaccid and erect states, which is produced pharmacologically. The change in penile blood volume is determined by measuring the change in the technetium-labeled red blood cell activity with time. Venous outflow is recorded with a xenon washout technique. The isotope data are used to compute arterial and venous flows with a complex computerized mathematical formula. Three basic blood flow patterns have been noted that distinguish normal patients from those with arterial insufficiency and venous leakage. The study is relatively easy and noninvasive to perform, and it appears to quantify penile blood flow accurately. © 1992 by The American Urological Association Education and Research, Inc.FiguresReferencesRelatedDetailsCited ByGILLON G and BARNEA O (2018) Erection Mechanism of the Penis: A Model Based AnalysisJournal of Urology, VOL. 168, NO. 6, (2711-2715), Online publication date: 1-Dec-2002.Pescatori E, Hatzichristou D, Namburi S and Goldstein I (2018) A Positive Intracavernous Injection Test Implies Normal Veno-Occlusive but Not Necessarily Normal Arterial Function: A Hemodynamic StudyJournal of Urology, VOL. 151, NO. 5, (1209-1216), Online publication date: 1-May-1994.
