The aim of this study is to describe the first series of six patients undergoing Retzius-sparing robot-assisted radical prostatectomy (rs-RARP) using the hinotori surgical robot system (hinotori SRS) and to compare the treatment outcomes with those achieved with the da Vinci surgical platform.
This study included 20 cases involving the rs-RARP procedure (hinotori: N = 6; da Vinci: N = 14) that were performed between May 2021 and April 2024 in a single institution.
No significant differences were observed between the hinotori and da Vinci groups regarding the preoperative findings. In the hinotori group, there were four cases of pT2 that showed negative surgical margins in all the cases. However, positive surgical margins were observed in two of the cases with pT3. The surgical outcomes were also similar between the two groups except for console time, which tended to be shorter in the da Vinci group ( = 0.058). There were no major complications in the initial six cases with the hinotori SRS. Immediate urinary continence was observed in 50% of the cases with the hinotori group compared with 64% for the da Vinci group.
This is the first study to report cases of rs-RARP performed on a hinotori SRS. It seems that the hinotori SRS shows similar treatment outcomes compared with the cases treated via the da Vinci platform.
本研究旨在描述首例六例接受 Retzius 间隙保留机器人辅助根治性前列腺切除术（rs-RARP）的患者，该手术使用 hinotori 手术机器人系统（hinotori SRS）进行，并将治疗结果与达芬奇手术平台的结果进行比较。
本研究包括 20 例接受 rs-RARP 手术的病例（hinotori：N=6；达芬奇：N=14），均在 2021 年 5 月至 2024 年 4 月在一家医院进行。
hinotori 组与达芬奇组在术前检查方面无显著差异。在 hinotori 组中，有 4 例 pT2 患者均显示切缘阴性，但有 2 例 pT3 患者显示切缘阳性。两组的手术结果也相似，除控制台时间外，达芬奇组倾向于较短（=0.058）。在使用 hinotori SRS 的最初六例中，没有出现重大并发症。hinotori 组中有 50%的患者立即出现尿控，而达芬奇组中有 64%的患者出现尿控。
这是首例报道使用 hinotori SRS 进行 rs-RARP 的研究。hinotori SRS 似乎与通过达芬奇平台治疗的病例具有相似的治疗结果。
