Objective To compare perioperative outcomes of early unclamping (EUC) vs standard unclamping (SUC) during robot-assisted partial nephrectomy (RAPN), as early unclamping of the renal pedicle has been reported to decrease warm ischaemia time (WIT) during laparoscopic PN. Patients and Methods A retrospective multi-institutional study was conducted at eight French academic centres between 2009 and 2013. Patients who underwent RAPN for a renal mass were included in the study. Patients without vascular clamping or for whom the decision to perform a radical nephrectomy was taken before unclamping were excluded. Perioperative outcomes were compared using the chi-squared and Fisher's exact tests for discrete variables and the Mann–Whitney test for continuous variables. Predictors of WIT and estimated blood loss (EBL) were assessed using multiple linear regression analysis. Results In all, there were 430 patients: 222 in the EUC group and 208 in the SUC group. Tumours were larger (35.8 vs 32.3 mm, P = 0.02) and more complex (R.E.N.A.L. nephrometry score 6.9 vs 6.1, P 50 procedures 12.2% vs 1.4%, P < 0.001). The mean WIT was shorter (16.7 vs 22.3 min, P < 0.001) and EBL was higher (369.5 vs 240 mL, P = 0.001) in the EUC group with no significant difference in complications or transfusion rates. The results remained the same when analysing subgroups of complex renal tumours (R.E.N.A.L. nephrometry score ≥7) or RAPN performed by less experienced surgeons ( |
