A total of 1650 measurements were taken for anterior\/posterior, medial\/lateral, cranial\/caudal, skin-to-calix distance, kidney-to-liver distance, and kidney-to-colon distance in both positions.<\/jats:p>\n <\/jats:sec>\n \n Results:<\/jats:title>\n \n Pronation shortens the distance from the skin to renal calix for both the right (99.62\u2009mm\n vs<\/jats:italic>\n 85.14\u2009mm;\n p<\/jats:italic>\n \u2009<\u20090.00001) and left (96.67\u2009mm\n vs<\/jats:italic>\n 90.80\u2009mm;\n p<\/jats:italic>\n \u2009<\u20090.00001) sides. The reduction in left-side tract length for obese patients is significantly greater than that of normal weight patients (11.88\u2009mm\n vs<\/jats:italic>\n \u22125.02\u2009mm;\n p<\/jats:italic>\n \u2009=\u20090.001).

The right kidney displaces cranially (62.76\u2009mm\n vs<\/jats:italic>\n 79.51\u2009mm;\n p<\/jats:italic>\n \u2009<\u20090.00001), while the left kidney does not (64.35\u2009mm\n vs<\/jats:italic>\n 66.52\u2009mm;\n p<\/jats:italic>\n \u2009=\u20090.14). The left kidney in females moves medially, while no change is seen in males (4.22\u2009mm\n vs<\/jats:italic>\n \u22120.48\u2009mm;\n p<\/jats:italic>\n \u2009=\u20090.0004). The left kidney in females displaces toward the descending colon, while it moves farther away in males (2.73\u2009mm\n vs<\/jats:italic>\n \u22122.01\u2009mm;\n p<\/jats:italic>\n \u2009=\u20090.011).\n <\/jats:p>\n <\/jats:sec>\n \n Conclusions:<\/jats:title>\n Both sex and body mass index had effects on the movement of the kidneys upon pronation.
