Abstract
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. Keywords: Penile elastography, erectile
