KangDuo surgical robot versus da Vinci robotic system in urologic surgery: a systematic review and meta-analysis

It was a systematic review and meta-analysis that aimed to compare the efficiency and safety of robot-assisted urological surgery using both the KangDuo and da Vinci robotic systems. The PubMed, Embase, and Cochrane Library databases were searched for all papers published through September 1, 2024. The focus was on English-language papers comparing the KangDuo surgical robot and the da Vinci system in urological procedures. The screening method focused on RCTs and cohort studies and followed strict criteria. Three cohort studies and two randomised controlled trials with 300 adult urological surgery patients met the inclusion criteria. These 150 patients were operated on with the KangDuo robotic system and 150 with the da Vinci system. The investigation showed that whereas KangDuo operations were slightly longer, intraoperative blood loss, hospital stay, and postoperative complication rates were similar. The KangDuo robotic system performs urological surgery as well as the da Vinci system, although it takes longer. Future large-scale multicenter randomized trials are recommended to gather further evidence and enhance clinical understanding.
