Objective. To evaluate the diagnostic value of computer cavernosography (CT cavernosography) in erectile dysfunction (ED) with a description of the technical aspects of the method.
Materials and Methods. The study included 350 patients with ED who underwent CT cavernosography between 2018 and 2025. Age, form of pathological venous drainage, concomitant changes in cavernous tissue, and complications were assessed.
Results. The average age of patients was 32±6.9 years. Signs of pathological venous drainage were detected in 88.57% of patients. The most frequently diagnosed types were mixed venous leakage (38.29%), proximal (31.14%), and distal (19.14%). Cavernous fibrosis was detected in 4.57% of patients. The frequency of complications was 3.4%.
Discussion. CT cavernosography demonstrated high sensitivity in detecting venous leakage, especially in complex forms. The method allows assessing not only vascular but also structural changes in cavernous tissue, including fibrosis and post-traumatic changes, which is critically important when planning surgical intervention.
Conclusions. CT cavernosography is a safe and highly informative method for diagnosing venogenic ED, allowing for accurate determination of the form of venous leakage, the degree of fibrosis, and the parameters of the cavernous bodies. The method can be recommended as a key diagnostic tool when planning surgical treatment for ED.
