Ultrasonic Testing Postures And Breathing To Study The Influence Of Kidney Position

Objectives: Ultrasonic testing space change of kidney anatomical location undersupine position, prone position, lateral position, prone position and Mat waistside-lying position，5kinds of anatomical changes, access to test data of mobilityand angle changes of kidney in different position and external cause under the role ofultrasonic.Methods: Using the technology of point tracking and continuous dynamic display,testing displacement distance of the three dimensions direction, fluctuation, left andright sides,before and after under Supine position, prone position, lateral position,prone position and Mat waist side-lying position and the data of before angle α andside angle β under quiet breathing, deep breaths of300left kidney,300right kidneyof300healthy volunteers, and a comparison study and statistical analysis.Results:Supine abdominal and lumbar left renal scintigraphy combined success rateof less than4.67%（14/300） satisfaction, satisfaction with the success rate of kidneyjoint imaging was significantly higher than the left kidney, about94.3%（283/300）;prone position, lateral position, prone position, abdominal pad, pad Waist lyingrenal scintigraphy combined success rate was100%satisfied, suitable for pointtracking and continuous dynamic display of the ultrasonic testing.On the displacement distance compared to quiet breathing supine position, proneposition, lateral position, pad Waist supine position under four kinds of threedimensions of the two kidneys (from top to bottom, front, left) of the displacementwas no significant difference in the distance, the pad under the ventral prone positionthe four position with a significant difference, in the prone position under the bellypad value is too small.Comparison of the former angle, the two kidneys in the abdominal pad under theprone position than in prone position, lateral position and supine Waist pad under the small values, there is a significant difference.Comparison of the former angle, the two kidneys in the abdominal pad under theprone position than in prone position, lateral position and supine Waist pad under thesmall values, there is a significant difference.Angle on the side of the comparison, the two kidneys in the lateral position andsupine Waist pad under the supine position than in the prone position and the proneposition under the belly pad value is too small, there is a significant difference.Angle on the front and side angle point in the next breath comparison of four, A.left kidney: first prone position angle, in the deep end inspiration than at end of quietbreathing, calm and deep end-expiratory end-tidal when the value is too large, thereare significant differences in the rest position under the former angle and side anglewas no significant difference; B. right kidney:①supine position under the side ofthe angle, in the deep end with the calm breathing and deep end-expiratory end-tidalwhen a significant difference;②under the prone position before the angle, in thedeep end-inspiratory end inspiration with the calm, quiet and deep end-expiratoryend-tidal when a significant difference;③pad under the ventral prone positionbefore the angle, in the quiet tidal breathing with the deep end, when the deepend-expiratory there was a significant difference;④pad lying ventral side angle,with the end of the Beiping-Tianjin inspiratory end-expiratory calm, deep breathingand deep breath at the end when the end of a significant difference, when in a calmand end-expiratory the end of deep inspiration and deep breath at the end when therewas significant difference; the rest position under the front angle and side angle wasno significant difference.Comparison of the left kidney and right kidney, left and right kidneys measuredvalues of the data was statistically significant (no significant difference among the18, there are significant differences in32).Take a deep breath and breathing calm when two of the kidney in side-lyingposition and Angle between the waist cushion side-lying position will have thereversal of the Angle, the corner in the deep breath appears when the breath to calm the frequency than high, than the left kidney right kidney appear the frequency tohigh.Conclusion:1、Ultrasound point tracking and continuous dynamic displaytechnology can detect the kidney in some different position and different breath thespace below the depth change position, providing more accurate ultrasound imagedata, can guide clinical operation2, Under the quiet breathing state, the move degree of normal bilateral renal from upto down is8.3mm to13.6mm,from before to after is1.1mm to1.8mm,from left toright is1.1mm to1.5mm，the movement of a three dimensions under Mat abdomenprone is the smallest.3, Underquiet breathing, the move degree of the right kidney of normal person undersupine position, side-lying position, mat waist side-lying position is than left kidney,the move degree of the bilateral renals from up to down have no difference,underprone position and mat abdomen prone.4, Normal person in the mat abdomen prone, and a side-lying position, mat waistside-lying position in four breathe some and prone in a deep breath left kidney tobefore the angle in greater than right kidney angle before.5, Normal person in the mat abdomen prone under a bilateral renal angle than purestomach before a measured values to the obvious small, in mat abdomen prone undera bilateral renal side angle than pure prone under a measured values slightly smaller.6, Normal person in the mat waist side-lying position, bilateral renal angle measuredvalues before a simple side under mild becomes a measured values, in the mat waistside with bilateral renal side under angle is purer side-lying position measured valuesunder mild smaller.7, Breathing to the influence of the before angle and the side angle, in addition to theleft kidney in a prone under angle before, right kidney in supine position of the sideangle and in the angle of a patient before, in the pad of abdominal prone a before in the pad Angle and waist side-lying position of side angle have statistical significance,the rest of the angle and breathing was not statistically significant.8, Side angle of the bilateral renal appears the reversal of the Angle under side-lyingposition and mat waist side-lying position when breathe in peace and in deepinspiration,the frequency of flip angle in the deep inspiration appear higher than inthe calm breathe, left kidney is higher than right kidney.9,2d ultrasound detection three dimensional space changes have strong experience,with the aid of some correction of control measures and can reduce the error rate.10, Kidney move up and down with the breathing process there may be slight rotationphenomenon, the value and significance of its rotation angle have to be studiedfurther.
