(PM-31) Three-dimensional imaging of penile deformity in Peyronie’s disease using an intraoral scanner: a feasibility study

Introduction Current clinical and research evaluations in Peyronie’s disease rely heavily on simplified curvature assessments of primary curvature, with limited standardization. Objective To evaluate the feasibility of using real time three-dimensional (3D) scan to objectively document complex penile deformities in real patients. Methods Three patients with Peyronie’s disease underwent 3D scanning using the Straumann SIRIOS™ intraoral scanner, during preoperative PDDU exam. Erection was achieved by intracavernosal injection with trimix with redosing if necessary to achieve a EHS 3-4 rigidity. A trained urologist performed the scans after a short training session, and timed with a chronometer. The images were reconstructed in real time and submited to posterior image rendering, using the default software, not specifically designed for penile defromities to create detailed 3D models. Image rendering was timed with a chronometer. Number of attempts wore documented, and if the reconstruction was considered inadequate, the process was restarted. Curvature was evaluated by 3 urologists with a goniometer and the presence of volume loss deformities (VLD) was recorded. Results High-resolution 3D models of penile deformities were successfully generated for all three patients. Number of attempts (P1 - 2; P2 - 3; P3 -1). The scanning times were (P1- 2:58; P2 -3:49; P3 - 1:37 minutes). 3D image rendering time was (P1 - 2:33; P2 - 1:23; P3– 2:58 minutes). Minor image artifacts were observed but did not interfere with deformity assessment. The procedure was well tolerated, and image acquisition was feasible with minimal operator training. Comprative curvature measurement data, absolute and percentual error, 3D accuracy and the ability to capture VLDs are reported at table 1. Conclusion 3D imaging with real time 3D scanner appears to be a promising and feasible technique for standardizing the assessment of complex penile deformities. Financing No conflict.
