(O-25) 3D documentation of complex penile deformities in peyronie’s disease – an experimental analysis of 2 devices

Introduction Cases of Peyronie’s Disease (PD) with complex deformities are challenging to report, due to its three-dimensional (3D) nature and the possible presence of volume-loss deformities (VLD). 3-D technology holds the potential to improve objective documentation. Objective To compare the feasibility of reporting complex penile deformities using 2 different portable 3D scanners. Methods Printed 3D models of different penile deformities with known measures were utilized to test the adequacy of 2 handheld scanners, the Einstar 3D Scanner ® (Hangzhou, China) – with infrared VCSEL structured light technology, and Straumann Sirios 2024 (Basel, Switzerland) a wireless digital oral scanner that generate 3D images in real time. Both were used to scan previously manufactured 3D-printed models with known deformities. The Einstein 3D reconstruction results was analyzed using a reverse engineering tool (Geomagic Design X, 3D Systems Inc., Rock Hill, EUA), while the Sirius results were evaluated with a goniometer by a trained urologist. Results The 3D reconstruction was possible in the first attempt for all models in the study. Einstein steps for the scans were similarly undertaken: a first pass over the model, during which the software communicated if the scan was effective through a color scale or sound. The 3D image quality was good and immediately visible at the screen. (Figure 1) A supplemental scan focusing on the indicated areas with missing images was performed. Sirius scan was also possible with real time 3D generated images, helping to guide the operator through the process. Final model is represented in Fig. 2. Measurements and time to capture images are displayed in Table 1. Volume loss deformity was visible since the first pass in all the scanners. Conclusion Quick and accurate 3D reconstruction was possible using 2 portable 3D scanners. Future work should investigate clinical applicability and overcome the need for manual measurements. Financing No conflict.
