The comparison of penile colour Doppler ultrasonography and pharmacocavernosometry in t he di- agnosis of venous impotence

Erectile dysfunction is the inability to achieve and maintain a firm erection for vaginal penetration. İt is shovvn that 50-90 % of the impotent men have organic causes. Main source of organic causes are vascular. Venous in- sufficiency is one of the vasculogenic disorders which is diagnosed by pharmacocavernosometry and phar- macocavernosography. Thirty men who complain from erectile dysfunction were diagnosed as venous impotence using pharmacocavernosometry. Penile colour Doopler ultrasonography was also carried out to evaluate the ve­ nous insufficiency. Using the results, diagnostic value of pharmacocavernosometry and colour Doppler ult­ rasonography were compared. Seven healty and potent men formed the control group. Colour Doppler ult­ rasonography confirmed the diagnosis of venous insufficiency in ali except three cases. Pharmacocavernosography shovved the localization of the venous leakes. The sensitivity of colour Doopler ult­ rasonography was 100 %, the specifity was 70 % and the accuracy rate was 91.89 %. As a result colour Doppler ultrasonography is an easy method which does not have complications except those resulting from drug injection. İt is a highly accurate method that does not necessitate volüme loading as in pharmacocavernosometry.
