Abstract：
Background: Variations in renal veins are quite common, and most people do not experience issues due to them. However, these variations are important for healthcare professionals, especially in surgical procedures and imaging studies, as precise knowledge of vascular anatomy is essential to avoid complications during medical interventions. The purpose of this study was to expose the frequency of anatomical variations in the renal vein (RV) and detail their relationship with the retroperitoneal and renal regions. Methods: A systematic search was conducted in the Medline, Scopus, Web of Science, Google Scholar, CINAHL, and LILACS databases from their inception until January 2024. Two authors independently carried out the search, study selection, and data extraction and assessed methodological quality using a quality assurance tool for anatomical studies (AQUA). Ultimately, consolidated prevalence was estimated using a random effects model. Results: In total, 91 studies meeting the eligibility criteria were identified. This study included 91 investigations with a total of 46,664 subjects; the meta-analysis encompassed 64 studies. The overall prevalence of multiple renal veins was 5%, with a confidence interval (CI) of 4% to 5%. The prevalence of the renal vein trajectory was 5%, with a CI of 4% to 5%. The prevalence of renal vein branching was 3%, with a CI of 0% to 6%. Lastly, the prevalence of unusual renal vein origin was 2%, with a CI of 1% to 4%. Conclusions: The analysis of these variants is crucial for both surgical clinical management and the treatment of patients with renal transplant and hemodialysis.
摘要：
背景：肾静脉的变异很常见，大多数人不会因为他们而遇到问题。然而,这些变化对医疗保健专业人员很重要，特别是在外科手术和影像学研究中，因为血管解剖学的精确知识对于避免医疗干预期间的并发症至关重要。这项研究的目的是揭示肾静脉（RV）解剖变异的频率，并详细说明它们与腹膜后和肾脏区域的关系。方法：在Medline进行了系统的搜索，Scopus,WebofScience,谷歌学者，CINAHL,和LILACS数据库从成立到2024年1月。两位作者独立进行了搜索，研究选择，和数据提取，并使用解剖学研究质量保证工具（AQUA）评估方法学质量。最终,合并患病率使用随机效应模型进行估计.结果：总的来说，确定了91项符合资格标准的研究。这项研究包括91项调查，共有46,664名受试者；荟萃分析涵盖64项研究。多个肾静脉的总体患病率为5％，置信区间(CI)为4%至5%。肾静脉轨迹的患病率为5%，aCI为4%至5%。肾静脉分支的患病率为3%,aCI为0%至6%。最后,异常肾静脉起源的患病率为2%，aCI为1%至4%。结论：这些变异的分析对于外科临床治疗以及肾移植和血液透析患者的治疗至关重要。
