Can the R.E.N.A.L Nephrometry Score Preoperatively Predict Postoperative Clinical Outcomes in Patients Undergoing Open and Laparoscopic Partial Nephrectomy?

摘要

Aim: We evaluate whether the preoperative R.E.N.A.L Nephrometry Score (RNS) can predict the postoperative outcomes in patients undergoing either an open or laparoscopic partial nephrectomy. Patients and Methods: We retrospectively calculated the RNS of 128 patients who underwent either an open partial nephrectomy (OPN) (n = 38) or laparoscopic partial nephrectomy (LPN) (n = 90) between 2003 and 2011. Patients were categorized into low, moderate or high complexity groups based on RNSs. Intra-opera-tive warm ischemic time (WIT), peri-operative surgical outcomes using the Clavien-Dindo classification, postoperative histology, positive surgical margin rates were correlated to the RNS.
