Abstract：Objective:To evaluate the predictive value of R.E.N.A.L.nephrometry score on complexity and outcomes of laparoscopic partial nephrectomy.Methods:From May 2006 to March 201 5,a consecutive series of 38 patients with renal cell carcinoma undergoing laparoscopic partial nephrectomywere retrospectively studied.Accord-ing to the R.E.N.A.L.scoring system,the patients were divided into three groups including low risk group (R.E. N.A.L.nephrometry score <7),median risk group (R.E.N.A.L.nephrometry score 7-9)and high risk group (R.E.N.A.L.nephrometry score ≥10).The operation time (OT),estimate blood loss (EBL),warm ischemic time (WIT)and serum creatinine (SC)change among these groups were compared.Results:There were 20 cases in low risk group.1 5 cases in median risk group,and 3 cases in high risk group.Importantly,the low risk group and median risk group showed significant difference in the OT [(1 1 9.3±47.21)vs .(1 58.7±36.27)min,P =0.01 1], EBL [(85.0±50.52)vs .(1 78.0± 1 63.06)mL,P =0.022],WIT [(36.3 ± 6.05 )vs .(42.1 ±4.75 )min,P =0.005]and SC [(18.1±8.65)vs .(30.2±14.91)μmol/L,P =0.005].Two of three cases were converted to lapa-roscopic radical nephrectomy in high risk group because of complexity of laparoscopic partialnephrectomy.Conclu-sions:R.E.N.A.L.scoring system is effective to predict the complexity of laparoscopic partialne phrectomy,and helpful for selecting patients suitable for this kind of operation according to the conditions of the surgeons and pa-tients.
