Introduction: No studies have shown whether the enhanced recovery after surgery (ERAS) protocol is superior to the conventional protocol after robot-assisted laparoscopic radical prostatectomy (RALP). We compared intestinal function and perioperative parameters of patients with prostate cancer after the ERAS and conventional protocols to determine the superior protocol for recovery of intestinal function. Material and Methods: A retrospective analysis of 198 consecutive patients who underwent RALP between August 2013 and June 2015 was conducted. Our study design included 2 cohorts. Patients underwent conventional care in one group (n = 123) and the ERAS protocol in the other group (n = 75). The primary outcome was the time to first defecation. Secondary outcomes were perioperative parameters and the complication rate. Results: The ERAS group showed a significantly shorter time to first defecation than did the conventional group (p = 0.006). Multivariate analysis showed that selection of the ERAS protocol was significantly associated with the number of days for first time to defecation. Conclusions: Successful application of an ERAS protocol was applied to our patients who underwent RALP and did not have major complications. The ERAS protocol included enhanced intestinal recovery. The ERAS group showed a significantly shorter time to first defecation than did the conventional group.

Various systemic inflammatory response biomarkers are associated with oncological outcome. We evaluated the superiority of prognostic predictive accuracy between neutrophil-lymphocyte ratio (NLR) and lymphocyte-monocyte ratio (LMR), and the prognostic significance of their perioperative change in patients with bladder cancer undergoing radical cystectomy (RC). We retrospectively analyzed 302 patients who had undergone RC in four institutions. Comparison of predictive accuracy between NLR and LMR was performed using receiver operating characteristic curve analysis. Overall survival (OS) and cancer-specific survival (CSS) were assessed with the Kaplan-Meier method and Cox regression analysis. Preoperative and postoperative LMR showed higher predictive accuracy for OS than NLR did (p = 0.034). Applying a cutoff of 3.41, change in perioperative LMR stratified patients into three groups (low, intermediate, and high risk), showing a significant difference in OS and CSS (p < 0.001, each), and pathological outcomes. Multivariable analyses for OS and CSS showed that poor changes in LMR (high risk) were an independent prognostic factor (hazard ratio 5.70, 95 % confidence interval 3.49-9.32, p < 0.001; hazard ratio 4.53, 95 % confidence interval 2.63-7.82, p < 0.001; respectively). Perioperative LMR is significantly associated with survival in patients with bladder cancer after RC, and it is possibly superior to NLR as a prognostic factor.

These findings suggest that too small graft size, frequent in female-to-male transplants, could cause hypertrophy in both kidneys and glomeruli, thereby affecting allograft function and survival.
