Aim: Peyronie’s disease (PD) or plastic induration of the penis, require complete evaluation of plaques in order to decide the best therapeutic option for patient. The purpose of this study is to compare the findings of three-dimensional ultrasound (3D US) and two-dimensional ultrasound (2D US) in patients with PD.

Materials and methods: Twenty patients with PD aged 30 to 72 years were included in study. The examination was performed with a 12 MHz linear probe, using 2D US and 3D US. Localization and size of plaques were determined and time needed for imagine acquisition was determined in every case.

Results: 3D ultrasound permits the visualization of the entire plaque in the coronal plane of plaque with its precise measurements. No statistical difference in plaque dimensions and its surface area assessment using 3D US and 2D US was found (127.72 mm² vs. 128.74 mm², p>0.05). The possibility to perform detailed analysis of the acquired images using generated digital cube reduced the average duration of the acquisition to 69.8 seconds (median 64 seconds) for 3D US vs. 151.25 seconds (median 145.5 seconds) for 2D US (p<0.05). A supplementary plaque was detected using 3D US.

Conclusions: 3D US seems to be a valuable complement of 2D US for patients with PD. The acquisition time is significantly reduced using 3D US comparing to 2D US and thus it is more comfortable for the patient.
