During the last several years, cavernosography has been commonly used to demonstrate the hemodynamic abnormality of the corpora cavernosa. But this was recognized as a less obvious, physiologic and objective study. Recently a more ideal method has been introduced and resulted in the development of the procedure entitled Dynamic Infusion Cavernosography (D.I.C.C). The DICC is done in four phase : phase I involves the determination of equilibrium corporeal body pressure and time required to reach the plateau. Phase II involves the determination of the rate of fall of corporal body pressure from a control pressure (150mmHg) over a defined observation period (30seconds). Phase III involves the determination of cavernosal arterial systolic occlusion pressure and finally phase IV involves the cavernosography at a predetermined corporal body pressure (90mmHg). Now, this procedure is performed as the first invasive erectile function test in those individuals considered for vascular reconstruction of their erectile problem.
