Purpose:
Robotic-assisted simple prostatectomy (RASP) has recently been studied as an alternative to open simple prostatectomy or endoscopic treatment options. At present, there is no defined recommendation for a robotic procedure as a standard surgical technique to treat large benign prostate hyperplasia.
Methods:
Several robotic techniques have been described since 2007. Contemporaneously, multiple endoscopic enucleation techniques have been proposed. Nevertheless, open simple prostatectomy still remains a mainstay of therapy. We aimed to evaluate the development of robotic-assisted prostatectomy for large benign prostatic obstruction, thus comparing the technical aspects and clinical outcomes with open and endoscopic enucleation.
Results:
Robotic-assisted simple prostatectomy provides significantly less blood loss and shorter hospital stay but longer operative time compared to open simple prostatectomy. Compared to endoscopic treatments, robotic approaches have a similar perioperative outcome, but cause less urethral trauma or potential bladder neck strictures. Moreover, concomitant bladder pathologies can be treated within the same setting.
Conclusion:
Robotic-assisted simple prostatectomy is an effective and safe technique, and can hence be considered to become the preferred first-line therapy to treat patients with obstructive large prostate glands.
