Abstract:
Objective:To discuss the variation rule of renal mobility measured by ultrasound and to establish the normality range of renal mobility of the pilot candidates.Methods:Kidney length, direct and indirect mobility of randomly selected 338 pilot candidates were measured. Intra-group correlation coefficient (ICC) was used to evaluate the repeatability of the kidney length measured by conventional ultrasound method and body surface projection method. The direct and indirect renal mobility was compared between the two methods and analyzed to establish the normality range of renal mobility.Results:①The ICC of right kidney length and left kidney length in decubitus and erect positions measured by conventional ultrasound and body surface projection were 0.759, 0.779, 0.725 and 0.754 ( P<0.01). ②The upper bound of the reference ranges of unilateral 90%, 95% and 99% of direct renal mobility was 2.00 cm, 3.00 cm and 4.12 cm in the right kidney and 2.32 cm, 2.70 cm and 3.56 cm in the left kidney, respectively. The upper bound of the reference ranges of unilateral 90%, 95% and 99% of indirect renal mobility was 5.00 cm, 5.50 cm and 7.31 cm in the right kidney and 5.40 cm, 5.71 cm and 6.69 cm in the left kidney, respectively. ③The regression equations of indirect and direct renal mobility were y=0.912 x+2.908 for the left kidney and y=0.956 x+2.726 for the right kidney. Conclusions:There are regular rules between direct and indirect renal mobility measured by ultrasound, and the normality range of renal mobility can be referenced in the medical selection of pilot candidates.
