Comment on: "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" by Dai et al.

We read with great interest the recent meta-analysis by Dai et al. comparing the KangDuo (KD) and da Vinci (DV) robotic systems in radical prostatectomy (RP). Their findings highlight the comparable perioperative outcomes of both systems despite longer operative times with KD. While the study provides valuable insights, we suggest incorporating console time as a key parameter reflecting surgical efficiency and proficiency. Additionally, a pooled analysis of biochemical recurrence (BCR) would enhance the oncological assessment of the two platforms. Lastly, the small sample size limits statistical power, underscoring the need for larger, multi-center studies. Addressing these aspects could further strengthen the study's clinical relevance.
