In situ injecting of the abdominal portion of the aorta and of the inferior vena cava allows exposure of the extra‐ and intraparenchymal portions of the renal arteries and veins. We describe the modality of obtaining aorto‐ and caval‐renal corrosion casts by in situ injecting. We used 30 retroperitoneal specimens in pig, injected with fluid methyl methacrylate (Technovit 7143) into the abdominal portion of the aorta and the inferior vena cava. After plastic polymerization, excision of the vascular wall was performed. Subsequently, we extracted the aorto‐ and caval‐renal blocks, and the renal parenchyma was corroded with Natrium Hydroxide. In 10 casts we injected also the pyelo‐ureteral system on one side. The initial injection of the pyelo‐ureteral system allows exposure of the real intraparenchymal distribution of the segmental arteries. The injection of only the abdominal portion of the aorta leads to flattening of the intraparenchymal arterial planes. The initial injecting of the inferior vena cava leads to flattening of the abdominal portion of the aorta due to contact with the left renal vein. (Supported by CNMP 42097/2008).
