title: [Pathogenetic criteria of nephroptosis].
abstract: The aim of the study was to specify treatment policy in nephroptosis on the basis of characteristics of the onset, development and course of the disease. A total of 83 patients with nephroptosis were examined. The rotation angles of the kidney were summed using standard excretory urograms in clino- and orthostasis. Radionuclide nephroscintigraphy, rheorenography were made in 72 patients. Statistical processing employed correlation, cluster, discriminant analysis of the program Statistica. The method of estimation of the angles of rotation of the movable kidney in three planes was introduced. Grouping of patients by the sum of the rotation angles appeared more precise in reflecting disorders of intraorganic circulation in the kidney than skeletotopic distribution by the nephroptosis degree. Standard excretory urograms allow determination of the sum of the angle of rotation of the movable kidney and, finally, adequate conservative or surgical treatment method. Surgery can correct disorders of intraorganic blood flow by creating physiological position for the kidney raising to the due level and eliminating rotation.
