PURPOSE To perform a systematic review and meta-analysis of the literature inherent robotic nephroureterectomy (RNU) and to compare its outcomes with those of other nephroureterectomy (NU) techniques. METHODS A systematic literature search was performed up to April 2019 using PubMed, Embase®, and Web of Science. The Preferred Reporting Items for Systematic Review and Meta-analysis Statement was followed for study selection. The following data were extracted for each study: baseline features, surgical outcomes, oncological outcomes, and survival outcomes. Stata® 15.0 was used for statistical analysis. RESULTS Literature search identified 80 studies eligible for the meta-analysis and overall 87,291 patients were included in the analysis: open NU (ONU; n = 45,601), hand-assisted laparoscopic NU (HALNU; n = 442), laparoscopic NU (LNU n = 31,093), and RNU (n = 10,155). RNU was more likely to be performed in those patients with multifocal tumor location (proportion: 0.19; 95% CI 0.14, 0.24) and high-grade disease (proportion: 0.70; 95% CI 0.53, 0.68). The lowest EBL was recorded in the RNU group (weighted mean (WM) 163.31 mL; 95% CI 88.94, 237.68), whereas the highest was in the ONU group (414.99 mL; 95% CI 378.52, 451.46). Operative time was shorter for ONU (224.98 mL; 95% CI 212.26, 237.69). RNU had lower rate of intraoperative complications (0.02; 95% CI 0.01, 0.05). ONU showed higher odds of transfusions (0.20; 95% CI 0.15, 0.25). LOS was statistically significantly shorter for the RNU group (5.35 days; 95% CI 4.97, 5.82). HALNU seemed to present lower risk of PSM (0.02; 95% CI - 0.01, 0.05), and lower risk of recurrence (0.22; 95% CI 0.15, 0.30), metastasis (0.07; 95% CI 0.05, 0.10), and cancer-related death (0.03; 95% CI 0.01, 0.06). ONU showed the lowest 5 years cancer specific survival (proportion: 0.77; 95% CI 0.74, 0.80). No correlation was found between the surgical technique and recurrence-free and cancer-specific survival. CONCLUSIONS Evidence regarding RNU for the treatment of UTUC is increasing but it remains quite sparse and of low quality. Despite this, RNU seems to be safe, and to offer the advantages of a minimally invasive approach without impairing the oncological outcomes. Nevertheless, ONU, HALNU, and LNU still represent a valid, and commonly used surgical treatment option. As RNU becomes more popular, and concerns related to its use remain, the best surgical technique for NU remains to be determined.

机器人与其他肾切除术的技术:超过87,000例的系统评价和荟萃分析。

目的对文献固有的机器人肾切除术(RNU)进行系统的回顾和荟萃分析,并将其结果与其他肾切除术(NU)技术进行比较。方法截至2019年4月,使用PubMed,Embase®和Web of Science进行了系统的文献检索。选择系统评价和荟萃分析陈述的首选报告项目。为每项研究提取了以下数据:基线特征,手术结果,肿瘤学结果和生存结果。使用Stata®15.0进行统计分析。结果文献检索确定了80项符合荟萃分析的研究,总共分析了87,291例患者:开放性NU(ONU; n = 45,601),手助腹腔镜NU(HALNU; n = 442),腹腔镜NU(LNU n)。 = 31,093),和RNU(n = 10155)。在多灶性肿瘤位置(比例:0.19; 95%CI 0.14,0.24)和高度疾病(比例:0.70; 95%CI 0.53,0.68)的患者中更可能进行RNU。RNU组的EBL最低(加权平均(WM)163.31 mL; 95%CI 88.94,237.68),最高的是ONU组(414.99 mL; 95%CI 378.52,451.46)。ONU的手术时间较短(224.98 mL; 95%CI 212.26,237.69)。RNU的术中并发症发生率较低(0.02; 95%CI 0.01,0.05)。ONU的输血几率更高(0.20; 95%CI 0.15,0.25)。RNU组的LOS在统计学上明显更短(5.35天; 95%CI 4.97,5.82)。HALNU的PSM风险较低(0.02; 95%CI-0.01,0.05),复发风险较低(0.22; 95%CI 0.15,0.30),转移率(0.07; 95%CI 0.05,0.10),与癌症相关的死亡(0.03; 95%CI 0.01,0.06)。ONU显示最低的5年癌症特异性存活率(比例:0.77; 95%CI 0.74,0.80)。在手术技术与无复发和癌症特异性生存之间未发现相关性。结论有关RNU治疗UTUC的证据正在增加,但仍相当稀少且质量低下。尽管如此,RNU似乎是安全的,并提供了微创方法的优点,而不会损害肿瘤学结果。尽管如此,ONU,HALNU和LNU仍然代表着有效且常用的外科治疗方案。随着RNU越来越流行,以及与它的使用相关的担忧仍然存在,关于NU的最佳手术技术仍有待确定。ONU显示最低的5年癌症特异性存活率(比例:0.77; 95%CI 0.74,0.80)。在手术技术与无复发和癌症特异性生存之间未发现相关性。结论有关RNU治疗UTUC的证据正在增加,但仍相当稀少且质量低下。尽管如此,RNU似乎是安全的,并提供了微创方法的优点,而不会损害肿瘤学结果。尽管如此,ONU,HALNU和LNU仍然代表着有效且常用的外科治疗方案。随着RNU越来越流行,以及与它的使用相关的担忧仍然存在,关于NU的最佳手术技术仍有待确定。ONU显示最低的5年癌症特异性存活率(比例:0.77; 95%CI 0.74,0.80)。在手术技术与无复发和癌症特异性生存之间未发现相关性。结论有关RNU治疗UTUC的证据正在增加,但仍相当稀少且质量低下。尽管如此,RNU似乎是安全的,并提供了微创方法的优点,而不会损害肿瘤学结果。尽管如此,ONU,HALNU和LNU仍然代表着有效且常用的外科治疗方案。随着RNU越来越流行,以及与它的使用相关的担忧仍然存在,关于NU的最佳手术技术仍有待确定。结论有关RNU治疗UTUC的证据正在增加,但仍相当稀少且质量低下。尽管如此,RNU似乎是安全的,并提供了微创方法的优点,而不会损害肿瘤学结果。尽管如此,ONU,HALNU和LNU仍然代表着有效且常用的外科治疗方案。随着RNU变得越来越流行,以及与它的使用相关的担忧仍然存在,关于NU的最佳手术技术仍有待确定。结论有关RNU治疗UTUC的证据正在增加,但仍相当稀少且质量低下。尽管如此,RNU似乎是安全的,并提供了微创方法的优点,而不会损害肿瘤学结果。尽管如此,ONU,HALNU和LNU仍然代表着有效且常用的外科治疗方案。随着RNU越来越流行,以及与它的使用相关的担忧仍然存在,关于NU的最佳手术技术仍有待确定。
