Male patient 38 yo, follow-up for CKD for years and now preparing hemodialysis by via kidney machine.
Ultrasound B-mode shows hyperechoic pattern of parenchymal and pyelonephritic structure both 2 kidneys but dimensions and vascular Doppler remain in normal ranges.
Elastography ultrasound for kidney was performed on ARFI SIEMENS S 2000, VTQ= 1.4-2.22m/sec
As the results, values of renal parenchymal stiffness increase slightly in 2 machines with 2 different technics of elastography ultrasound.
DISCUSSIONS:
1/ Shear wave
elastography
and ARFI technic may be a low-cost way to provide additional
diagnostic information in CKD.
2/ Our case with increased values of both ARFI for CKD from 1.4--2.22m/s and SWE measurements
= 22-24kPa that proves a heterogeneicity of kidney, and the complex parenchymal stiffness
which may lead to fibrosing of kidney in progress.
