title: [Impact of preoperative nutritional risk on complications after radical cystectomy].
abstract: OBJECTIVE
  To evaluate whether urological patients at nutritional risk are at higher risk for complications after radical cystectomy than those not at nutritional risk.
  
  
  METHODS
  We performed a retrospective observational study in the consecutive patients undergoing radical cystectomy between 2010 and 2013. A total of 147 patients were enrolled in this study. The nutritional risk score was assessed preoperatively by a specialized study nurse. The patients with NRS (nutritional risk screening, NRS2002)scores≥3 were considered to have nutritional deficiency. Postoperative complications were defined using the standardized Clavien-Dindo classification. Univariate and multivariate analyses were performed to identify the predictors of complications.
  
  
  RESULTS
  The patients aged ≥70 years(50.57%) were more prone to nutritional risk than those aged <70 years (31.67%, P=0.023). Of the 63 patients at nutritional risk, 39 (61.90%) presented with at least 1 complication compared with 29 of the 84 controls (34.52%, P=0.001). The patients at nutritional risk were at threefold risk for complications on binary Logistic analysis (OR=3.128,95%CI 1.538-6.361,P=0.002). The length of hospital stay of the patients at higher nutritional risk was longer than that of those without nutritional risk [(12.9±5.7) d vs. (10.4±4.3) d, P=0.003].
  
  
  CONCLUSIONS
  The patients aged ≥70 years are at higher nutritional risk than that of those aged <70 years. Patients at nutritional risk are more prone to complications after radical cystectomy.
