However, this model is greatly simplified for clarity and symmetry. Some of the other paths and complications are described at the bottom of the table. The interlobar artery and vein (not to be confused with interlobular) are between two renal lobes, also known as the renal column (cortex region between two pyramids).
The human urinary system, also known as the urinary tract or renal system, consists of the kidneys, ureters, bladder, and the urethra. The purpose of the urinary system is to eliminate waste from the body, regulate blood volume and blood pressure, control levels of electrolytes and metabolites , and regulate blood pH .
The renal cortex is the outer portion of the kidney between the renal capsule and the renal medulla. [1] In the adult, it forms a continuous smooth outer zone with a number of projections (cortical columns) that extend down between the pyramids.
The arcuate vein is a vessel of the renal circulation.It is located at the border of the renal cortex and renal medulla. [citation needed] Arcuate veins pass around the renal pyramids at the border between the renal cortex and renal medulla in an arch shape. [1]

X-rays are taken at specific time intervals to capture the contrast as it travels through the different parts of the urinary system. [7] At the end of the test, a person is asked to pass urine and a final X-ray is taken. [7] Before the test, a person is asked to pass urine so that their bladder is emptied. [5]
Each column consists of lines of blood vessels and urinary tubes and a fibrous material. A hypertrophied renal column (or renal pseudotumor) may be differentiated from an actual renal tumor with the help of a DMSA scan. The scan will show the area as one with normal activity if it is a pseudotumor or will show decreased uptake if it is a cystic ...
