The accessory renal arteries (ARAs) are a well-described variant of the renal vasculature with clinical implications for radiologists, surgeons, and clinicians. The aim of the present systematic review with meta-analysis was to estimate the pooled prevalence of ARAs, including their variant number, origin, and termination, and to highlight symmetrical and asymmetrical morphological patterns. The systematic review used four online databases in accordance with PRISMA 2020 and Evidence-based Anatomy Workgroup guidelines. R programming software was used for the statistical meta-analysis. A total of 111 studies were considered eligible for our initial aim. The typical renal artery (RA) anatomy (a single bilateral vessel) was identified in 78.92%; the overall ARA prevalence was estimated at a pooled prevalence of 21.10%. The estimated pooled prevalence of one, two, three, and four ARAs were 18.67%, 1.80%, 0.01%, and <0.01%. The ARAs have been the subject of extensive research owing to their clinical importance, including in kidney transplantation surgery and resistant hypertension therapy. Knowledge of the typical and variant anatomy of RAs is essential for anatomists, radiologists, surgeons, and clinicians in order to avoid misunderstanding, complications, and iatrogenic injury.
副肾动脉（ARAs）是一种已被充分描述的肾血管变异，对放射科医生、外科医生和临床医生具有临床意义。本项带有荟萃分析的系统评价旨在评估副肾动脉的合并患病率，包括其变异数量、起源和终止情况，并突出对称和不对称的形态学模式。该系统评价根据PRISMA 2020和循证解剖学工作组指南使用了四个在线数据库。使用R编程软件进行统计荟萃分析。共有111项研究被认为符合我们的初始目标。78.92%的研究发现了典型的肾动脉（RA）解剖结构（单一双侧血管）；副肾动脉的总体患病率估计为合并患病率21.10%。一条、两条、三条和四条副肾动脉的估计合并患病率分别为18.67%、1.80%、0.01%和<0.01%。由于副肾动脉在临床中的重要性，包括在肾移植手术和顽固性高血压治疗中的重要性，它们一直是广泛研究的对象。了解肾动脉的典型和变异解剖结构对于解剖学家、放射科医生、外科医生和临床医生来说至关重要，以避免误解、并发症和医源性损伤。
