Surgical and Functional Outcomes of Robotic-Assisted Radical Prostatectomy in Patients with Previous Transurethral Resection of the Prostate

Abstract

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 3 rd 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 1 st 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.
