To evaluate the colour duplex sonography as a non-invasive technique in comparison to the invasive and discomfort dynamic cavernosometry / cavernosography as a new tool for diagnosis of venogenic impotence, we recruited 24 patients; showed repeated negative reactions to 60 mg papaverine injection. Those 24 patients were independently examined by colour duplex sonography imaging (CDI) after 60 mg papaverine injection and by dynamic cavernosometry/cavernosography (CVM).Of the 24 patients, 3 patients (12.5%) showed arterial insufficiency (A.I) as proved by colour duplex sonography (V... < 20 cm/sec.). Those patients were excluded from the study. Of the remaining 21 patients; 20 patients (83.3%) showed consistent diagnoses by both modalities. Those consistent patients were fallen into two groups. The first group showed venous leakage (V.L) and included 15 patients (75%) while the second group showed no venous leakage (NL) and included 5 patients (25%). The remaining patient (4.2%) showed different diagnosis by both modalities. He was diagnosed as VL by CDI and NL by CVM.Student’s (t) test was used to detect differences and significance of different parameters for the 20 consistent patients with V . > 25 cm/sec. either with or without venous leakage. The differences between the group with venous leakage and the groupPage No. (79)Summarywith no venous leakage were found to be highly significant for V.ia and resistance index (R.I) parameters (P < .001) while V.0 parameter was found to be less significant between the two groups (P < 0.05). By correlating results of colour duplex sonography and those of dynamic cavernosometry / cavernosography we obtained:•Specificity40.833•Sensitivity4100%.•Predictive value of the positive test493.7%.•Predictive value of the negative test4100%.•Diagnostic accuracy499.9%.We conclude that dynamic colour duplex scanning can be used as a screening procedure to diagnose significant venous leakage for deciding the need for the invasive dynamic cavernosometry / cavernosography especially when venoligation or arterial revascularization surgeries are being arranged.Page No.180)
