This paper is concerned with the study on the cross section of the upper abdomen insufflated air with the technique of the retropneumoperitoneum. 24 healthy adults, operated with air, were rotatory cross section radiographed with the same technique as was described in the Tohoku J. Exp. Med., Vol. 54, 1, 1951 and were examined. Four cross sections, upper area of the kidney, the center between the upper pole and hilum, hilum and the center between hilum and the lower pole were roentgenographed. Each of them was parallel to the base cross section which containes hilum of the kindey. The results obtained were as follows : 1) In the first cross section the area of the extraperitoneal areolar tissue is imaged in the right side of the abdomen smaller as the one in the left side. 2) In the second cross section aorta thoracicus, vena cava inf., the spleen and the head of the pancreas are visualized clearly in each topographical position. 3) The size of the kidney shaped hen egg with smooth contour is counted 4.9×3.7 cm at the . second and the fourth cross section and' is counted 5.6×4.7 cm at the third cross' section on an average. 4) While the longitudinal axis of the right kidney inclines to the saggital plane with 42°, that of the left does 44°. 5) The position of the kidney in the cross section of the abdomen is plotted with the polar coordinate system under the consideration of the statistical control.
