Renal column

The renal column or column of Bertin is a distinctive structure in the kidney. It is named after the French anatomist, Exupère Joseph Bertin.

Etymology

The term "renal column" is derived from the Latin word "renalis" meaning "of the kidneys" and the Latin word "columna" meaning "pillar". The term "column of Bertin" is named after Exupère Joseph Bertin, a French anatomist who first described this structure.

Anatomy

The renal columns are extensions of the cortex that project into the medulla and separate the most distinctive functional parts of the medulla, the renal pyramids. They are located between the renal pyramids. The renal columns consist of lines of blood vessels and urinary tubes and are supported by a fibrous material.

Function

The renal columns' main function is to allow the cortex to be anchored. They also serve as a space for blood vessels and urine-carrying tubes to pass through from the cortex to the medulla.

Clinical significance

In certain medical conditions, such as hydronephrosis, the renal columns can become more prominent. This can be seen on medical imaging such as ultrasound or computed tomography (CT) scans.
