Background:
This study aimed to investigate the perioperative outcomes of robot-assisted laparoscopic pyeloplasty (RLP) using the recently launched hinotori surgical robot system.
Methods:
This retrospective study compared the perioperative outcomes of 11 consecutive patients who underwent RLP with the hinotori surgical robot system from October 2022 to March 2024 (hinotori group) and 30 consecutive patients who underwent RLP with the da Vinci system from March 2019 to September 2022 (da Vinci group).
Results:
The patient characteristics of the groups were similar. The median operative times in the hinotori and da Vinci groups were 236.0 and 231.5 min, respectively (p = 0.480). The success rates were 100.0% and 96.7%, respectively (p = 1.000). Clavien-Dindo grade ≥ 3 complications occurred in one patient (9.1%) in the hinotori group and one patient (3.3%) in the da Vinci group (p = 0.470).
Conclusions:
The perioperative outcomes in the hinotori group were not inferior to those in the da Vinci group.
