N2 - Objectives: To evaluate the effect of previous robot-assisted radical prostatectomy (RARP) case volume on the outcomes of robot-assisted radical cystectomy. Little is known regarding the effect of previous robotic surgical experience on the implementation and execution of robot-assisted radical cystectomy. Methods: Using the International Robotic Cystectomy Consortium database, 496 patients were identified who had undergone robot-assisted radical cystectomy by 21 surgeons at 14 institutions from 2003 to 2009. The surgeons were divided into 4 groups according to their previous RARP experience (≤50, 51-100, 101-150, and >150 cases). The overall operative time, blood loss, lymph node yield, pathologic stage, and surgical margin status were compared among the 4 groups using chi-square analysis. Results: The mean operative time was 386 minutes (range 178-827). The mean estimated blood loss was 408 mL (range 25-3500). The operative time and blood loss were both significantly associated with previous RARP experience (P < .001). The mean lymph node count was 17.8 nodes (range 0-68). Lymph node yield and increased pathologic stage were significantly associated with previous RARP experience (P < .001). Finally, 34 (7.0%) of the 482 patients had a positive surgical margin. Margin status was not significantly associated with previous RARP experience (P = .089). Conclusions: Previous RARP case volume might affect the operative time, blood loss, and lymph node yield at robot-assisted radical cystectomy. In addition, surgeons with increased RARP experience operated on patients with more advanced tumors. Previous RARP experience, however, did not appear to affect the surgical margin status.
