PURPOSE The role of robotic partial nephrectomy (RPN) is becoming increasingly prevalent in managing small renal masses. Renal functional outcomes have been reported with relation to the amount of healthy renal parenchyma resected and ischemia time; however, there is limited data on the effect of renorrhaphy on long-term renal function. Our aim is to evaluate the impact of renorrhaphy technique on renal functional outcomes. METHODS A nonsystematic literature review was performed to retrieve articles assessing renorrhaphy techniques and renal function outcomes, specifically focusing on single-layer vs. traditional two-layer renorrhaphy. RESULTS Performing single-layer renorrhaphy while omitting cortical renorrhaphy appears to improve renal function postoperatively, based on very limited studies in the literature that were evaluated. CONCLUSION Single-layer renorrhaphy may be associated with improved postoperative renal function and could prove to be useful in patients with chronic renal insufficiency or solitary kidney. The ongoing clinical trial NCT02131376 may provide further information on the impact of renorrhaphy technique on long-term renal function.

机器人肾部分切除术的肾脏修复技术和对肾功能的影响。

目的 机器人肾部分切除术 (RPN) 在治疗小肾肿块方面的作用越来越普遍。据报道，肾功能结果与切除的健康肾实质数量和缺血时间有关；然而，关于肾脏修复术对长期肾功能影响的数据有限。我们的目的是评估肾脏修复技术对肾功能结果的影响。方法 进行了一项非系统性文献回顾以检索评估肾移植术技术和肾功能结果的文章，特别关注单层与传统的两层肾移植术。结果 根据评估的文献中非常有限的研究，进行单层肾镜修补术而省略皮质肾镜修补术似乎可以改善术后肾功能。结论 单层肾脏修复术可能与术后肾功能的改善有关，并可能被证明对慢性肾功能不全或孤立肾患者有用。正在进行的临床试验 NCT02131376 可能会提供有关肾脏修复技术对长期肾功能影响的进一步信息。
