Aim. The aim is to study the changes in topography of the retroperitoneal organs at body position on the back and in the lateral position. Material and Methods. Data of multispiral CT-scan of 36 patients with body position on the back and lateral side were studied. 19 patients were with the left side, 17 with the right side body position. There were 19 women (52.8%) and 17 men (47.2%). The middle age was 57.3±12.2 year. The system of coordinates has been offered. The vertical line through the center of the vertebra body (OY axis) was drawn. The perpendicular line through middle of spinal canal was drawn (OX axis). Results and Discussion. The measurements of the right side showed the following: concerning the OX axis the superior pole is displaced on a distance of 19.9±6.5 mm, the kidney at the level of the hilum on a distance of 20.3±6.3 mm, the inferior pole - 28.6±14.6 mm. Superior pole of the right kidney approaches to OX axis on a distance of 5.5±1.9 mm, at the level of the hilum on 10.3±5.0 mm, the lower pole - 23.6±10.3 mm. The identical measurement of the left side showed that concerning the OX axis the superior pole is displaced on a distance of 16.6±7.7 mm, at the level of the hilum 21.3±6.3 mm, the inferior pole - 30.8±10.1 mm. In relation to the OY axis the left kidney at the level of the superior pole is displaced on a distance of 8.2±4.0 mm, at the level of the hilum on a distance of 13.5±7.2 mm, inferior pole - 31.8±12.3 mm. The vertical displacement of the kidney attracts attention: upward shift was found in 11 cases, and average displacement is on a distance of 11.5±5.9 mm; the downward shift was observed in 25 cases (17.2±8.4 mm on average). Conclusions. Displacement of the left kidney at all levels was higher than the displacement of the right kidney.
