Intraoperative frozen section of the prostate decreases positive margin rate while ensuring nerve sparing procedure during radical prostatectomy.

Purpose: We evaluated whether intraoperative frozen section analysis of the prostate surface might provide significant information to ensure nerve sparing and minimize the positive margin rate.

Materials And Methods: In 236 patients treated with radical prostatectomy between June 2011 and September 2012 whole surface frozen section analysis of the removed prostate was done intraoperatively. The apex and base were circumferentially dissected as well as the whole posterolateral tissue corresponding to the neurovascular bundles.
