Background: Partial nephrectomy (PN) is the standard treatment for localized renal tumors where nephron preservation is feasible. The evolution of minimally invasive surgery has progressed from conventional two-dimensional laparoscopy to three-dimensional (3D) laparoscopy and, more recently, to robotic-assisted techniques. Although robotic and laparoscopic PN have been widely compared, evidence focusing on a complete transition from 3D laparoscopy to robot-assisted partial nephrectomy (RAPN) remains scarce. Methods: This retrospective single-surgeon study included 80 consecutive patients treated between 2018 and 2024, encompassing the full transition period from 3D LPN to RAPN. Thirty-six patients underwent 3D laparoscopy and forty-four underwent robotic surgery, excluding the first ten robotic cases representing the learning phase. Propensity score weighting was applied to minimize baseline differences. Results: Tumors treated with RAPN had significantly higher RENAL scores (median 8 vs. 6,p= 0.001), indicating greater complexity, while perioperative outcomes—including hospital stay, operative time, and complication rates—remained comparable. Warm ischemia time was significantly shorter in the RAPN group (17.5 vs. 22 min,p= 0.005), and the TRIFECTA rate was higher though not statistically significant. Conclusions: These results indicate that a complete transition from 3D laparoscopy to robotic partial nephrectomy is safe and feasible, maintaining or improving outcomes even in more complex tumors and broadening the applicability of nephron-sparing surgery.
背景:对于可行肾单位保留的局限性肾肿瘤,部分肾切除术(PN)是标准治疗方法。微创手术的发展已从传统的二维腹腔镜手术演进至三维(3D)腹腔镜手术,并进一步发展到机器人辅助技术。尽管机器人辅助与腹腔镜部分肾切除术已被广泛比较,但聚焦于从3D腹腔镜完全过渡至机器人辅助部分肾切除术(RAPN)的证据仍较为有限。 方法:本回顾性单外科医生研究纳入2018年至2024年间连续治疗的80例患者,覆盖了从3D腹腔镜部分肾切除术(3D LPN)到RAPN的完整过渡期。其中36例患者接受3D腹腔镜手术,44例接受机器人手术,并排除了代表学习阶段的最初10例机器人手术病例。研究采用倾向评分加权法以最小化基线差异。 结果:RAPN组治疗的肿瘤RENAL评分显著更高(中位数8分 vs. 6分,p=0.001),表明肿瘤复杂性更高,但围手术期结果——包括住院时间、手术时间和并发症发生率——保持相当。RAPN组的温缺血时间显著缩短(17.5分钟 vs. 22分钟,p=0.005),TRIFECTA达标率更高,但未达到统计学显著性。 结论:这些结果表明,从3D腹腔镜完全过渡至机器人部分肾切除术是安全可行的,即使在更复杂的肿瘤中也能维持或改善手术效果,从而拓宽了肾单位保留手术的适用范围。
