In our experience, some patients with normal DUS result still vasculogenic erectile dysfunction (ED), indicating that current measurements may be incomprehensive. study, a new parameter, Flow Index (FI), was introduced for evaluating arteriogenic ED. METHODS: Patients receiving computed tomography angiography (CTA) evaluation ED were enrolled. defined based on observed EHS after intracavernous injection PGE1 during exam. veno-occlusive excluded. Pelvic arterial (PLA) stenosis cavernous (CA) measured CTA. velocity*π*radius2. We FI=PSV*(1-arterial stenosis%)2. FI PLA (FIPLA) CA (FICA) calculated. Correlations between parameters assessed. RESULTS: Eighty-three included. Compared PSV, had better correlations (Table) area under receiver operating characteristic curve (AUC) (Figure). without ED, who more severe (62.50% vs 30.00%, P=0.02) lower FIPLA (12.03 42.17, P=0.01), while PSV different (37.50 cm/s 39.90 cm/s, P=0.54). stenosis, odds higher (OR=4.88) (56.00 67.60, P=0.03 FICA; 10.22 58.53, P<0.01 FIPLA), however, significantly (35.00 38.25 P=0.38). CONCLUSIONS: comprehensive than in patency one factors determining penile perfusion. However, suitable diagnosing stenosis.
