Only surgeons who performed more than five radical prostatectomies (by any approach) over the study period are included in this table. Within that group, only patients with a high risk (≥2%) of lymph node involvement by preoperative nomogram, who had lymph node dissection performed, are included.

RP=radical prostatectomy; IQR=interquartile range.
