Where is the inferior segmental renal artery located?
It is located at the renal hilum, arising from the main renal artery and passing anterior to the renal pelvis before coursing inferiorly to the inferior pole of the kidney.
What is the function of the inferior segmental renal artery?
Its function is to supply oxygenated blood to the entire inferior pole of the kidney, covering both the anterior and posterior surfaces of the inferior lobe.
What conditions may affect the inferior segmental renal artery?
Renal lower-pole tumors, ureteropelvic junction obstruction surgery, and renal trauma may be associated with involvement of the inferior segmental renal artery, making its identification important in lower-pole partial nephrectomy.
How is the inferior segmental renal artery examined or imaged?
CT angiography is the primary modality used to identify and map the inferior segmental renal artery prior to partial nephrectomy or other renal interventions.
