Robotic radical perineal prostatectomy: tradition and evolution in the robotic era

PURPOSE OF REVIEW: To provide an updated review of robotic radical perineal prostatectomy (r-RPP) with emphasis on the recent advances in terms of surgical technique, outcomes, and new robotic platforms. RECENT FINDING: The technological innovations in the urological field have been applied to radical prostatectomy with the aim of preserving important anatomical structures and reduce patients' morbidity and mortality. In recent years, robotic surgery contributed to resurge radical perineal prostatectomy. In 2014, the Cleveland Clinic group was the first to demonstrate the utility of a robotic approach in RPP. To date, the majority of the reported studies showed that r-RPP has noninferior perioperative, short-term oncological, and functional outcomes compared with the traditional robot-assisted radical prostatectomy (RARP). Given these benefits, r-RPP is a promising approach in selected patients, such as obese ones. Moreover, robotic perineal pelvic lymph node dissection performed through the same incision of r-RPP and the new Single-Port (SP) Robotic System represent further steps towards the overcoming of some intrinsic limitation of this surgical approach making this technique suitable for a larger number of patients with prostatic cancer. SUMMARY: Overall, r-RPP represents a reliable and effective novel surgical technique. However, more studies with long-term follow-up are needed to clarify the advantages over RARP.
