Comparison of the Hinotori surgical robot with the da Vinci robotic system in radical prostatectomy: a systematic review and meta-analysis.

In recent years, the adoption of robot-assisted surgery for prostatectomy has seen a significant increase. Among the various systems available, the da Vinci system has established itself as the standard in this domain. Meanwhile, the Hinotori Surgical Robotic System (HSRS) has garnered attention as a promising emerging technology. This paper seeks to systematically evaluate and conduct a meta-analysis comparing the efficacy and safety of HSRS with the da Vinci system in the context of radical prostatectomy (RP). We searched multiple databases, including PubMed, Embase, Cochrane Library, and Web of Science, to identify studies that utilized HSRS in the context of RP, specifically those comparing it with the da Vinci system. The meta-analysis incorporated five studies that collectively involved a total of 779 patients. The findings indicated that the HSRS cohort experienced a significantly longer operative time compared to the Da Vinci cohort (WMD = 20.42, 95% Cl (6.25, 34.59), p < 0.05). Moreover, the console time for the HSRS cohort was also significantly extended (WMD = 24.14, 95% Cl (16.74, 31.53), p < 0.05). No substantial differences were evident between the two cohorts regarding estimated blood loss, length of stay, urinary incontinence, occurrence of major complications, and the presence of positive surgical margins. In RP, HSRS is associated with extended operative and console times; however, it is similar to the da Vinci system in terms of tumor efficacy and functional recovery. While HSRS demonstrates encouraging clinical applications, there remains a pressing need for extensive, multicenter, high-quality studies to thoroughly assess its effectiveness.
