What is the kidney B-ultrasound? How to identifyresult of the ultrasonic examination?
(1) normal renal volume (length x width x thickness) :
The left kidney: adult 10.26 + / - 0.06 * 4.45 + / - 0.05 * 4.75 + / - 0.05 cm (men), female 9.85 + / - 0.11 * 4.1 + / - 0.04 * 4.47 + / - 0.04 cm,
Male. Right kidney: 10.16 + / - 0.06 * 4.21 + / - 0.05 * 4.54 + / - 0.04 cm, female 9.85 + / - 0.11 * 4.06 + / - 0.06 * 4.43 + / - 0.06 cm.
The double renal diameter is less than 9 cm and the size of the kidney is smaller than 7 centimeter. it is larger than 12.5cm.
The size of the kidney can determine whether the disease is acute or chronic.
(2) the identification of renal mass is cystic or substantial.
(3) hydronephrosis: the diagnostic coincidence rate is 90%.
(4) evaluation of transplantation renal function: after transplantation, the renal volume suddenly increased, indicating acute rejection, and the kidney shrank when the blood creatinine was increased in late transplantation.
(5) select suitable puncture points and depth of injection.
(6) urinary bladder residual urine: immediately after urination, the urinary volume of urinary bladder can be calculated.
