Robot-assisted radical prostatectomy – A single institute experience

Purpose: The aim of this study was to describe surgical, oncological and functional outcomes for patients undergoing robot-assisted radical prostatectomy (RARP)

Materials and Methods: From 2009 to November 2015, total 362 patients with prostate cancer were treated with robot-assisted radical prostatectomy at Taipei Veterans General Hospital. We collected patient and tumor characteristics. Perioperative outcomes, oncologic outcome, and functional outcomes were recorded.

Results: Total 362 patients were included in our study. The mean age was 63.35 ± 5.23 and the mean body mass index was 25.0 ± 2.36. Mean pre-operation PSA was 11.7 ± 6.37. Mean estimated blood loss was 190.7 ± 191.92ml. Mean days of Foley removal was 5.6 ± 2.63. Mean days of post-op hospital days was 6.65 ± 1.85. Complications occurred in 75 cases (20%), with 58 gradeI, 12 gradeII, 2 gradeIIIa, and 3 gradeIIIb by Clavien-Dindo classificaiton. Positive surgical margin was 28%. Continence rate was 85.56% % after 1 year follow-up. Potency rate was 60.81% after 1 year follow-up. Biochemical recurrence rate was 13.56%. Mean follow-up period was 28.24 ± 17.89 months. Factor will influence biochemical recurrence including value of PSA, gleason score, risk group, and margin status.

Conclusion: According to our study and literature review. RARP is a safe procedure with regard to perioperative results. Functional outcome was better than previous study in our hospital.
