Purpose: The purpose of this study was to assess the surgical and functional outcomes of robotic-assisted radical prostatectomy (RARP) in patients with previous transurethral resection of the prostate (TURP). Materials and Methods: The present article studies 99 patients who underwent RARP, including 13 patients with previous TURP at a single institution, in the period from April 2016 to February 2019. Propensity score matching 1:1 was performed to identify 13 patients with no previous TURP. The matched variables were age and preoperative prostate-specific antigen level. Surgical and functional outcomes were compared between the two groups. Descriptive statistics were evaluated using the Chi-square test. t-test was performed for continuous variables. Results: Regarding preoperative characteristics, no previous TURP group had a higher clinical stage (P = 0.026). The nerve-sparing procedure was similar between the two groups. Concerning intraoperative outcomes for the group with previous TURP history, the operating room time was increased by 25 min (P = 0.140), and the estimated blood loss was increased by 50 ml (P = 0.192). As for the postoperative pathological characteristics, there was no significant difference in the positive surgical margin rate between the two groups. The continence rate in the 3rd month for the group with previous TURP history was 69.2% versus 92.3% for the group with no previous TURP history, and after the 1st year, the rates were 100% versus. 92.3%. There was no significant difference in the potence recovery rate between the two groups after 1-year follow-up. Conclusion: RARP is safe and feasible in patients with localized prostate cancer with previous TURP history. Functional outcomes after 1-year follow-up were comparable for patients with previous TURP.
