Background: To present our experiences with partial nephrectomy (PN) through retroperitoneal approach (RP) with the Kangduo robotic system.Methods: From December 2020 to February 2021, the perioperative data of 11 patients underwent PN through RP with the Kangduo robotic system were collected prospectively.Results: For the R.E.N.A.L. nephrometry score, 72.7% of patients had a low score (4-6) and 27.3% of patients had a medium score (7-9). Seven tumours were posterior (P), four tumours were on the midline (X). All procedures were completed successfully. The median warm ischemia time was 18.5 (IQR, 13.7-21.0) min. None of the patients had positive surgical margins at definitive histology (all pT1a). No high-grade perioperative complications or device-related adverse events occurred.At a mean follow-up of 8 � 0.8 months, no complications occurred in all patients.
