The primary objective of the EASY survey (Evaluation de l'Acceptation deS injections dans la dYsfonction érectile) was to study the feelings of patients treated for erectile disorders with long-term intracavernous injections of prostaglandin E1. The major criteria for abandoning treatment with IPDE 5 are, in descending order, inefficacy, cost and poor tolerance. Regarding the results with intracavernous injections of Edex, around 80% of patients were satisfied; 70 to 80% of those treated for risk factors and/or cardiovascular or neurological diseases and 55% of those treated following cancer of the prostate claimed that their sex life had improved.
