The uterine artery (UA) is an arterial branch of the internal iliac artery in women, usually arising from the anterior division of the internal iliac artery. However, due to the high variability in the anatomy of the UA, embolization of this vessel may be challenging. Therefore, the objective of this meta‐analysis was to provide physicians with transparent data on the anatomy of the UA, using the available data in the literature. Databases such as PubMed, Scopus, Embase, Web of Science, and Google Scholar were searched to find all the relevant studies regarding the UA. A total of 16 articles met the required criteria. The UA was found to originate most frequently from the internal iliac artery as the pooled prevalence was set to be 61.72% (95% CI: 41.31%–80.31%). A pooled prevalence of the UA originating from the umbilical artery was established at 13.93% (95% CI: 2.76%–30.44%). A pooled prevalence of the UA originating from the inferior gluteal artery was set to be 5.22% (95% CI: 0.00%–15.44%). In conclusion, we believe that this is the most accurate and up‐to‐date study regarding the highly variable anatomy of the UA. The UA originates most frequently from the internal iliac artery (61.72%), however, other origins, such as from the umbilical artery (13.93%) or the inferior gluteal artery (5.22%) may occur. It is hoped that the results of the present meta‐analysis will be a helpful tool for surgeons performing pelvic or gynecological surgeries.
