“…In our study 13(25%) patients were smoker, among smokers 8(61%) patients had vasculogenic ED, compare to 5(38%) patients with non vasculogenic ED Table 4 & (Graph 4). Furthermore, our study highlights the potential interaction of buergers disease with ED [11][12][13][14][15]. Buerger disease was present in 5(9.6% patients) all of them were smokers and 4 out of 5 (80%) were suffering from vasculogenic ED.…”

“…In efforts to further characterize cavernous inflow disease, CDU parameters have been expanded: EDV and RI. Currently, PSV is commonly used to diagnose arterial insufficiency [11], and EDV and RI, which represent intracavernous vascular resistance, are used to diagnose veno-occlusive dysfunction [12].…”

Objective: We studied the relationship between penile hemodynamic parameters assessed by color Doppler ultrasonography and penile rigidity estimated by objective measurement. Patients and Methods: A total 37 patients with erectile dysfunction were examined. After intracavernous injection of 20 µg prostaglandin E₁, we measured their penile hemodynamic parameters in the cavernous arteries by color Doppler ultrasonography. Simultaneously, the RigiScan Plus device was used for real-time evaluation of penile rigidity. Hemodynamic parameters were correlated with penile rigidity. Results: Peak systolic velocity and resistive index were significantly correlated with penile tip (r = 0.54, r = 0.72, respectively) and base (r = 0.55, r = 0.76, respectively) rigidity; there was no significant correlation between end-diastolic velocity and penile rigidity. Conclusions: Peak systolic velocity and resistive index were strongly correlated with penile rigidity in patients with erectile dysfunction during intracavernous pharmacological testing. The resistive index in particular appeared to be the most valid parameter for assessment of penile rigidity.

“…The overwhelming majority of patients at the Mayo Clinic evaluated for erectile dysfunction undergo a color duplex Doppler of the penile arteries [1][2][3][4]. This evalua tion is performed after intracorporal injection (0.25 ml) of a mixture of papaverine (4.4 mg), phentolamine (0.15 mg), and prostaglandin E| (PGE|t 1.5 gg).…”

Veno-occlusive dysfunction has become a recognized cause of organic impotence. The existence of concomitant arterial and sinus smooth-muscle disease makes this disorder often difficult to diagnose. It rarely can be the sole etiology for impotence. The authors’ experience in the treatment of this disorder in over 100 patients is presented. The authors rely on cavernosometry/pharma-cocavernosometry/pharmacocavernosography and the color duplex Doppler screening test (to eliminate concomitant arterial disease) as the primary diagnostic tools. Twenty-two patients of 58 (38%) have achieved long-lasting success from the surgery so that they are able to have vaginal intercourse. Another 12 patients (21 %) have been improved but must depend upon pharmacological injection therapy to obtain a sufficient erection for intercourse. There has been a 41% failure rate, and these are discussed.
