Figure 1. a–c.

Example of dissection plan that was changed according to the nerve-sparing (interfascial) technique. Images of a 58-year-old man with a PSA level of 5.8 ng/mL and biopsy (Gleason score 4+4=8) performed for five of the ten cores on the right. Digital rectal examination revealed abnormalities on the right side of the prostate. Non-nerve sparing dissection was initially planned on the right side in accordance with the biopsy. MRI showed no involvement of the neurovascular bundles or seminal vesicles but revealed a tumor adjacent to the capsule. MRI images of T2-weighted (a) and diffusion phases (b) were focused on the tumor at the right posterolateral gland. The right interfascial dissection plan was performed, and the final pathology (c) had a Gleason score of 4+4, confirming the images that showed no extracapsular extension on the right posterolateral gland with negative surgical margins
