title: [Early diagnostic signs of complicated course of hypermobile kidney].
abstract: OBJECTIVE
  To develop a method for early diagnosis of renal venous blood flow disorders as a factor determining complicated course of hypermobile kidney (HK).
  
  
  METHODS
  Rotation angles in the three coordinate planes and six static conditions were determined in 92 patients with HK (in 3312 coordinate planes and in 1104 the static state). The fixed probe and "dancing kidney" method was used. The same 92 patients underwent polypositional Doppler sonography in six static states. Statistical analysis was performed using the statistical software STATISTICA 7.0 (Statsoft Inc., USA).
  
  
  RESULTS
  In 226 (93%) patients with HK SAD exceeded 30 mm Hg in at least one static state. Evaluation of 552 variants in assessing hemodynamic features of hypermobile kidney revealed that 92 patients had signs of impaired unilateral or bilateral renal vein outflow as determined by RMS and dVven. in 415 (75.18%) cases. The accuracy in determining belonging to the group, according to the classification matrices of STATISTICA 7.0 software was 89.13%.
  
  
  CONCLUSIONS
  The developed methods for evaluating kidney rotation make it possible to diagnose significant disturbances of the renal major blood flow and monitor dynamics of the process in real-time. All disturbances of the renal major blood flow occur only in ptosis and rotation; that confirms the need for early diagnosis of these conditions.
  
  
  CONCLUSIONS
  The findings of the multi-positional study of HK and the results of the data mathematical processing suggest that our method of HK imaging enables screening to determine the group of patients in need of further examination and observation.
