Hospital readmissions after limited vs. extended lymph node dissection during open and robot-assisted radical prostatectomy.

Purpose: Differences exist concerning when and how to perform lymph node dissection (LND) during radical prostatectomy due to lack of high-grade evidence to its safety and efficacy. We aimed to compare readmission rates between limited and extended LND during open radical prostatectomy (ORP) and robot-assisted radical prostatectomy (RARP).

Materials And Methods: We conducted a prospective trial of 3,706 eligible patients comparing ORP vs.
