Clinical and Economic Assessment of Robot-Assisted Radical Prostatectomy With the Hinotori Surgical System: Insights From a Japanese Single-Centre Study

Abstract

Background: We investigated the clinical and economic outcomes of robot-assisted radical prostatectomy (RARP) using the hinotori surgical system (H-RARP). Methods: The analysis was conducted on 76 and 68 patients who underwent RARP using the da Vinci surgical system (D-RARP) and H-RARP, respectively. Safety, oncological, and functional outcomes were compared between H-RARP and D-RARP. Risk factors influencing medical costs in RARP were identified via linear regression analysis. Results: Except for longer operative time in H-RARP, clinical outcomes were comparable. The median medical costs per case were $12,426.8 for D-RARP and $12,548.9 for H-RARP. Operative time (coefficient: 0.0002, p < 0.001), pathological T stage (coefficient: 0.023, p = 0.030), and postoperative hospital stay (coefficient: 0.028, p < 0.001) were significant factors affecting medical costs; in contrast, the type of robot-assisted surgical system was not a significant factor. Conclusions: H-RARP offers clinical outcomes comparable to those of D-RARP while maintaining equivalent medical costs.
