DorlandsSuf =In the kidney, the renal papilla is the location where the Medullary pyramids empty urine into the renal pelvis. Histologically it is marked by medullary collecting ducts converging to channel the fluid. Transitional epithelium begins to be seen.

Role in disease

Some chemicals toxic to the kidney, called nephrotoxins, exert their damage at the renal papillae. Damage to the renal papillae may result in death to cells in this region of the kidney, called renal papillary necrosis.
