AIDS Nephropathy


HIV-associated nephropathy consists of a pentad of findings, including (1) proteinuria, (2) azotemia, (3) normal-to-large echogenic kidneys on ultrasonography images, (4) normal blood pressure, and (5) focal segmental glomerulosclerosis on renal biopsy findings. There is both tubulointerstitial and glomerular components.

Ultrasound examination shows bilateral renal enlargement with increased echogenicity compared to the liver.

Gray scale ultrasound images of left and right kidneys shows bilaterally enlarged and echogenic kidneys in this patient with HIV and acute renal failure. Both kidneys measured approximately 16 cm and demonstrated increased echogenicity to the renal cortex and loss of normal corticomedullary differentiation. Arrows define the upper and lower poles of the kidneys.
