CASE 614: ELASTOGRAPHY ULTRASOUND for a Case of CKD, Dr PHAN THANH HẢI, Dr NGUYỄN NGHIỆP VĂN, MEDIC MEDICAL CENTER, HCMC, VIETNAM

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

and SWE Supersonics machine= 22-24kPa.

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.
