Huang MM, Patel HD, Su ZT, et al. - This study was intended to assess the correlation of post-radical prostatectomy (RP) drain placement with post-operative complications and opioid use at a high-volume institution. Researchers performed a prospective, comparative cohort study of patients undergoing robot-assisted or open RP. The appropriate statistical tests and logistic regression were applied to conduct intention-to-treat primary analysis and additional secondary analyses. A total of 498 total patients were included in the study. No variation was found in adverse events, complications, symptomatic collections, or opioid use with deferral of routine drain placement after RP. The results considered that experienced surgeons may safely defer drain placement in the majority of robot-assisted RP cases.
