The safety and feasibility of robotic-assisted radical prostatectomy (RARP) compared with retropubic radical prostatectomy(RRP) is debated. Recently, a number of large-scale and high-quality studies have been conducted.

To obtain a more valid assessment, we update the meta-analysis of RARP compared with RRP to assessed its safety and feasibility in treatment of prostate cancer.
A systematic search of Medline, Embase, Pubmed, and the Cochrane Library was performed to identify studies that compared RARP with RRP. Outcomes of interest included perioperative, pathologic variables and complications.
78 studies assessing RARP vs. RRP were included for meta-analysis. Although patients underwent RRP have shorter operative time than RARP (WMD: 39.85 minutes; P < 0.001), patients underwent RARP have less intraoperative blood loss (WMD = -507.67ml; P < 0.001), lower blood transfusion rates (OR = 0.13; P < 0.001), shorter time to remove catheter (WMD = -3.04day; P < 0.001), shorter hospital stay (WMD = -1.62day; P < 0.001), lower PSM rates (OR:0.88; P = 0.04), fewer positive lymph nodes (OR:0.45;P < 0.001), fewer overall complications (OR:0.43; P < 0.001), higher 3- and 12-mo potent recovery rate (OR:3.19;P = 0.02; OR:2.37; P = 0.005, respectively), and lower readmission rate (OR:0.70, P = 0.03). The biochemical recurrence free survival of RARP is better than RRP (OR:1.33, P = 0.04). All the other calculated results are similar between the two groups.
Our results indicate that RARP appears to be safe and effective to its counterpart RRP in selected patients.
