Digital frozen section of the prostate surface during radical prostatectomy: a novel approach to evaluate surgical margins.

Intra-operative tailoring of surgical dissection during radical prostatectomy (RP) can be performed with the help of either 3D-augmented reality or frozen section analysis [1]. The latter with the purpose of maximizing nerve-sparing (NS) RP has evolved into the NeuroSAFE, a dissection technique of the prostatic surface limited to the neurovascular(NV)-structure-adjacent-prostatic-tissue aiming to detect cancer persisting at the NV-area [2].
