Objective Histopathologically to determine the relationship between penile elastography ultrasonography and erectile dysfunction. Material and Method 12 patients who applied to our clinic for erectile dysfunction in the last 1 year and accepted this study were included . Preoperative two-dimensional shear wave elastography imaging was performed in 12 patients and recorded in the Pascal (kPa) unit. Approximately 0.5x0.5x0.5 cm tissue samples were taken from the right and left spongy tissue during penile prosthesis implantation operation. Tissue samples were sent to the pathology department. The percentage of the area covered by muscle fibers and elastic fibers in the corpus cavernosum was noted semi-quantitatively (ratio of muscle fibers and cavernous body elastic fiber score). All data obtained were compared with each other. Results Cavernous body elastic fiber score data(Grouped Score 1, 2 and 3) and percentage of cavernous body muscle fibers data (Grouped %10,%20,%30… %100) were compared with Shear wave elastography data (kPa). The results were not statistically significant according to the Kruskal Wallis Test and Spearman’s correlation test. Cavernous body elastic fiber score and the percentage of cavernous body muscle fibers were also compared, it was not statistically significant according to the Kruskal Wallis test and Spearman’s correlation test. The data we obtained as a result of our study showed that penile elastographic imaging is not a reliable method in the diagnosis of erectile dysfunction. Conclusions Penile shear wave elastography can be used clinically to quantitatively assess the amount of smooth muscle cells and elastic fibers in the penis, but it deserves to be studied with a larger number of patients and a more specific interpretation of the pathology preparation.
