Implementation of Intraoperative Frozen Section During Radical Prostatectomy: Short-term Results from a German Tertiary-care Center.

Background: Neurovascular bundle (NVB) preservation (NVBP) and surgical margin status are the main intraoperative factors influencing functional and oncologic outcomes in patients with prostate cancer undergoing radical prostatectomy (RP).

Objective: To test the impact of implementing the intraoperative frozen section technique (IFST) during NVBP on the frequency of NVB procedures and its effect on positive surgical margins (PSMs).

Design, Setting, And Participants: We relied on an institutional tertiary-care center database to identify patients who underwent RP (January 2014-October 2018).
