INTRODUCTION: Robot-assisted partial nephrectomy (RAPN) using the da Vinci Surgical System (DVSS) is broadly performed globally. In Japan, the Hinotori Surgical Robot System (HSRS) has recently been developed. However, few studies have compared perioperative outcomes between HSRS-RAPN and DVSS-RAPN. This study aimed to compare perioperative outcomes between these two robotic platforms.
METHODS: Clinical data from 86 patients who underwent RAPN from April 2023 to November 2025 were prospectively collected and retrospectively analysed. Propensity score matching (1:1) based on preoperative variables yielded 31 matched pairs. Perioperative outcomes, including trifecta achievement, were compared.
RESULTS: Following matching, baseline characteristics were well balanced. Operative parameters, perioperative complications, positive surgical margins, postoperative renal function, and trifecta rates did not significantly differ between the groups.
CONCLUSIONS: HSRS-RAPN can be safely and effectively performed, achieving perioperative outcomes comparable to those of DVSS-RAPN. These findings suggest that HSRS is a feasible alternative robotic platform for RAPN.
