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 eleven 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 tumors were posterior (P), four tumors were on the midline (X). All procedures were completed successfully. The median warm ischemia time was 18.5 (IQR, 13.7-21.0) mins. 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.

Conclusions

RPPN using the novel Kangduo robotic system is a safe and effective option for managing posterior and lateral renal tumors with R.E.N.A.L. nephrometry scores ≤ 9.
