Potency and urinary continence are adversely affected post-prostatectomy. The primary objective is oncological safety by ensuring negative surgical margins (NSM) and best functional recovery through nerve preservation in appropriate patients. NeuroSAFE technique of intra-operative frozen-section (IFS) analysis was devised for comprehensive assessment of surgical margins adjacent to the neurovascular tissue surface of the prostate. We analyzed our initial experience with this technique. Five NS-RARPs were performed utilizing the NeuroSAFE technique between October 2021 and February 2022. Patient demographics, disease stage, operative console time, post-operative complications, final histopathology, biochemical recurrence (BCR), erectile function, and urinary continence were recorded. The mean age of patients was 59.2 ± 1.3 years. All had clinically organ-confined disease with ISUP grade ≤ 3. The mean operative time of NS-RARP with NeuroSAFE was 240 ± 21 min and average NeuroSAFE time was 45 ± 3.8 min. All patients had NSM on IFS. No patient had Clavien-Dindo grade > 1 complications. Margins were negative on final histopathology. No patient had BCR at 6 and 12 weeks. Three patients were able to have sexual intercourse and only one patient required single precaution pad at 12 weeks. NeuroSAFE is feasible and can ensure intra-operative oncological safety of the NS procedure. Moreover, it gives the opportunity to convert positive surgical margin to prognostically favorable NSM by secondary resection. Our initial experience which is the first in India is encouraging with favorable functional outcomes. Large prospective studies and longer follow-up are required specially to evaluate the oncological benefit.
