METHOD OF ULTRASONIC TESTING OF RENAL PARENCHYMA AT CHILDREN Russian patent published in 2008 - IPC A61B8/00 

FIELD: medicine; urology; nephrology; surgery; oncology.

SUBSTANCE: ultrasonic scanning of kidney is carried out, followed by calculation of volume of kidney. Ultrasonic scanning of kidney is performed by means of Voluson 730 Expert (GE, USA) diagnostics apparatus by application of detector for three-dimensional reconstruction RAB 2-5. By means of Vocal program, angle of cut of volumetric image is assigned within 9-30° range. Calculation of volume of kidney of preset cuts for number of images of 6-20 is performed. Results of calculation are summed automatically and volume of kidney (V_kidney) and volume of kidney sinus (V_kidneysinus) is achieved. Volume of renal parenchyma is calculated by means of formula of V_parenchyma, _cm ³=V_kidney, _cm ³-V_{kidneysinus, cm} ³. Relation of volumes of internal structures (S, %) is calculated from formula of S=(V_kidneysinus/V_parenchyma) x100%. In case S belongs to 14-21%, normal relation of intra-renal structures can be testified. In case the value exceeds 21%, sclerosis of kidney's parenchyma is diagnosed.

EFFECT: improved efficiency of testing; higher precision.
