Potential Contenders for the Leadership in Robotic Surgery

Purpose: To summarize the scientific published literature on new robotic surgical platforms with potential use in the urological field, reviewing their evolution from presentation until the present day. Our goal is to describe the current characteristics and possible prospects for these platforms. Materials and Methods: A nonsystematic search of the PubMed, Cochrane library's Central, EMBASE, MEDLINE, and Scopus databases was conducted to identify scientific literature about new robotic platforms other than the Da Vinci® system, reviewing their evolution from inception until December 2020. Only English language publications were included. The following keywords were used: "new robotic platforms," "Revo-I robot," "Versius robot," and "Senhance robot." All relevant English-language original studies were analyzed by one author (R.F.) and summarized after discussion with an independent third party (E.M., S.Y., S.P., and M.A.). Results: Since 1995, Intuitive Surgical, Inc., with the Da Vinci surgical system, is the leading company in the robotic surgical market. However, Revo-I®, Versius®, and Senhance® are the other three platforms that recently appeared on the market with available articles published in peer-reviewed journals. Among these three new surgical systems, the Senhance robot has the most substantial scientific proof of its capacity to perform minimally invasive urological surgery and as such, it might become a contender of the Da Vinci robot. Conclusions: The Da Vinci surgical platform has allowed the diffusion of robotic surgery worldwide and showed the different advantages of this type of technique. However, its use has some drawbacks, especially its price. New robotic platforms characterized by unique features are under development. Of note, they might be less expensive compared with the Da Vinci robotic system. We found that these new platforms are still at the beginning of their technical and scientific validation. However, the Senhance robot is in a more advanced stage, with clinical studies supporting its full implementation.
