Inferior Segmental Artery of Kidney

Arteria segmenti inferioris renis

Read more


The inferior segmental artery is one of four branches of the anterior branch of the renal artery that usually occurs in the hilum of the kidney (renal sinus).


The inferior segmental artery passes anterior to the renal pelvis, inferiorly and laterally towards the inferior pole of the kidney.


The inferior segmental artery gives rise to interlobar branches, usually one for each renal pyramid within the inferior lobe of the kidney.

Supplied Structures

The inferior segmental artery supplies the inferior lobe of the kidney, which encompasses the whole of the inferior pole of the kidney, including the anterior and posterior surfaces (Rani et al., 2014).

List of Clinical Correlates

- The segmental arteries of the kidney are virtual end arteries. They supply non-overlapping “segments” of kidney tissue. In other words, the segments are defined by the vascular territories of the segmental arterial branches. This has important implications in kidney segmental resection.

When the artery is occluded blood is forced through the collateral vessels, drastically increasing fluid shear stress and triggering an inflammatory response which drives vessel remodeling.
