Positive Margins in Laparoscopic Partial Nephrectomy in 855 Cases: A Multi-Institutional Survey From the United States and Europe

Abstract

Early experience with laparoscopic partial nephrectomy in this multicenter study demonstrates oncological efficacy comparable to that of open partial nephrectomy with respect to the incidence of positive margins. The practice of intraoperative frozen sections varied among centers and is not definitive in guiding the optimal surgical treatment.
