We were intrigued by the recent article by Li and coworkers [ [1] Li X, Xu W, Fan S, et al. Robot-assisted partial nephrectomy with the newly developed KangDuo Surgical Robot versus the da Vinci Si surgical system: a double-center prospective randomized controlled noninferiority trial. Eur Urol Focus. In press. https://doi.org/10.1016/j.euf.2022.07.008. Google Scholar ] on their evaluation of the proficiency, effectiveness, and safety profile of the new KangDuo Surgical Robot (KD-SR) robotic platform recently developed and introduced in China. The authors aimed to expand evidence from previous studies that demonstrated promising results for the KD-SR system in procedures such as radical prostatectomy [ [2] Fan S. Zhang Z. Wang J. et al. Robot-assisted radical prostatectomy using the KangDuo Surgical Robot-01 system: a prospective, single-center, single-arm clinical study. J Urol. 2022; 208: 744https://doi.org/10.1097/JU.0000000000002838 Crossref Scopus (1) Google Scholar ] and pyeloplasty [ [3] Fan S. Xiong S. Li Z. et al. Pyeloplasty with the KangDuo Surgical Robot vs the da Vinci Si robotic system: preliminary results. J Endourol. 2022; 36: 1538-1544https://doi.org/10.1089/end.2022.0366 Crossref Scopus (2) Google Scholar ]. The aim in their current study was to further establish the capabilities of the KD-SR system by demonstrating its noninferiority to the da Vinci Si surgical system in the robotic excision of low-complexity cT1a renal tumors (RENAL score ≤9).
