Objective To investigate the uterine artery's origin, branching patterns, and relation to the ureter in a Kenyan population. Method The uterine arteries of the bodies of 53 girls and women were dissected at the University of Nairobi Department of Human Anatomy to study these patterns. Data were analyzed for frequency and the patterns are presented via digital macrographs. Results The uterine artery consistently originated as a branch of the internal iliac artery. It formed the second or third branch of the anterior trunk in 70.8% of cases; it ascended as a single branch, or from a bifurcation, or from a trifurcation in 76.4%, 17.1%, and 6.7% of cases; and lay posterior to the ureter in 3.8% of cases. In all, 46.2% of the uterine arteries studied varied from the classic description. Conclusion About half of the uterine arteries had a nonclassic origin, branching pattern, or relation to the ureter—as a posterior relation to the ureter had not been previously described. Surgeons operating in the pelvis should be aware of this variant anatomy to avoid injury to the ureter and other organs.
