Renal papilla Definition

It is the apex or highest point of each renal pyramid that projects into a calyx. In other words, it is any of the triangular tissue sections that constitute the medulla – the white fatty material of the kidneys.

Renal papilla Location

It is a part of the kidney.

Renal papilla Appearance

The surface of this tissue section looks like a sieve. It comprises of numerous small apertures (openings) from which droplets of water can pass.

Renal papilla Function

It transports urine produced in the cortical section of the kidney to the cup-like cavities (calyces) where the urine gets accumulated before passing into the bladder through the ureter.

Renal papilla Disorders

Certain toxic chemicals, known as nephrotoxins, are harmful to the kidney and cause damage to the renal papillae. This can lead to the death of cells in this kidney region and give rise to a condition, known as Renal Papillary Necrosis. This disorder commonly arises due to dehydration, along with NSAIDs like Acetylsalicylic acid, Phenylbutazone, and Ibuprofen.
