Origin
The posterior branch of the renal artery is formed by the bifurcation of the renal artery into two main branches next to, or at, the renal hilum.
Course
The posterior branch of the renal artery travels almost horizontally. The artery takes a lateral course and travels posteriorly to the ureter.
Branches
The number of posterior branches of the renal artery varies between individuals. They continue to divide, passing to the renal columns within the cortex of the kidney, before terminating as the glomeruli of the nephron.
Supplied Structures
The posterior branch of the renal artery supplies the medulla and cortex of the kidney.
