A systematic review and meta-analysis comparing the short-term efficacy of the KangDuo surgical robot with the da Vinci robotic system in radical prostatectomy.

To determine the efficacy and adverse consequences between KangDuo and Da Vincii surgical robotic systems in facilitating radical prostatectomy. All the papers, that were included in the current analysis, were identified with PubMed, Embase, and the Cochrane Library through October 1, 2024. To make the comparison easier, only the English-language articles have been used for the analysis and only those focusing on comparing the use of the KangDuo and da Vinci robotic systems in radical prostatectomy were used. There are several avenues of bias when considering articles to include, when selecting the articles for this study to adopt the RCTs and cohort studies and excluding the others, the bias selection targeted was minimal. For the systematic review, 1 cohort study was found as well as 2 RCTs were found that involved 150 adult patients assigned to undergo urological surgery. Of those, 76 patients operated by the Kang Duo robotic system, and the remaining 74 patients operated by the Da Vinci system. In conclusion from this study, it was noted that though there was an increase in the operative time used in the KangDuo system, the estimated blood loss, number of days needed to stay in hospital, and the incidences of postoperative complications were comparable to the other system. Compared to the da Vinci robotic system, the KangDuo robotic system, while associated with longer operative times for radical prostatectomy, showed no significant difference in perioperative or short-term outcomes. In addition, the KangDuo system is more cost-effective and easier to implement in developing countries or other regions. However, further high-quality studies are needed to confirm these findings.
