Abstract
The renal collecting ducts empty via the ducts of Bellini into the area cribrosa of the renal papillae. The morphology of the orifices of the collecting duct emptying into the area cribrosa is of interest because of the relationship to intrarenal reflux and pylonephritic scarring. The purpose of this paper is to anatomically characterize these ductal orifices using scanning electron microscopy in the normal adult human kidney and to discuss possible pathological implications.Renal papillae were obtained from autopsy material of five normal adult human kidneys that were initially fixed in 10% buffered formalin. Three papillae were randomly selected from each kidney for a total of 15 papillae. The specimens were washed in distilled water, 0.5N hydrochloric acid, and again in distilled water. Surface debris were gently removed with a fine camel hair brush as needed. The samples were postfixed in osmium tetroxide, washed in distilled water, dehydrated in a graded series of ethanols, mounted on aluminum stubs, and sputter coated with gold-palladium. The specimens were examined in a JE0L JSM-35 scanning microscope at 25KV.
