Robot-assisted radical prostatectomy following holmium laser enucleation of the prostate: Perioperative, functional, and oncological outcomes

Abstract

Abstract Robot-assisted radical prostatectomy with previous holmium laser enucleation of the prostate is challenging, and few studies have analyzed its perioperative, functional, and oncological outcomes. Here we retrospectively evaluated 298 robot-assisted radical prostatectomies, including 25 with and 273 without previous holmium laser enucleation of the prostate, performed in 2015–2022. Regarding perioperative outcomes, operative and console times were significantly longer in the previous holmium laser enucleation of the prostate group. In contrast, the estimated blood loss was similar between groups, and there were no transfusions or intraoperative complications. Multivariable Cox hazard regression analysis of the functional outcomes of postoperative urinary continence showed that body mass index, intraoperative bladder neck repair, and nerve sparing were independently associated factors, whereas a history of holmium laser enucleation of the prostate was not. Similarly, a history of holmium laser enucleation of the prostate was not associated with biochemical recurrence; however, positive surgical margins and seminal vesicle invasion were independent risk factors of biochemical recurrence. Our findings revealed that robot-assisted radical prostatectomy after holmium laser enucleation of the prostate was safe and raised no concerns of postoperative urinary incontinence or biochemical recurrence. Therefore, robot-assisted radical prostatectomy may be a treatment option for patients with prostate cancer after holmium laser enucleation of the prostate.
