The aim of this study is to investigate the morphological structures on the renal parenchyma on the pig kidneys, prepared in thin slices by S10 sheet plastination method. A total number of 60 kidneys taken form two adult breeds are plastinated in 2mm sagital thin sections. The morphological structure on thin kidney slices is analyzed and their anatomic-topographical relationship is investigated. The prepared thin kidney slices are permanent, flexible, dry, and odorless with smooth surfaces anatomical models with clear distinction between renal medulla and renal cortex. In cross-bread landras/yorkshire, the number of renal pyramids is ranged between 8-14 (average 10.63) while in breed dalland the number is ranged between 8- 13(average 9.94)(p>0.05). Three morphological forms are found in pig kidneys based of the variation of adhesion of renal pyramids and derange of their renal papilla into renal pelvis. According the results can be concluded that the S10 sheet plastination method could be used for preparing of thin anatomical models that are suitable for education and research purposes enabling three-dimensional plan view of anatomical structures inside of kidneys.
