E-mail: radiovet@ufrrj.br Dioctophyma renale is the largest nematode of dogs. Usually affects the right kidney. This work describes the ultrasonographic findings of three dogs naturally infected with D. renale with a worm in the right kidney. The B-mode ultrasonography is a good method to identify D. renale in dog’s kidneys. Doppler ultrasound was useful to identify kidneys vascular anatomy in non parasitized animal without evidence of renal failure. The lack of Doppler signal in parasitized kidneys was compatible with tissue injury caused by the parasite. Doppler signal reduction in non parasitized kidneys from animal with renal failure indicates a renal perfusion reduction. Studies using Doppler ultrasound on various renal diseases should be performed for better characterization of ultrasonographic findings of the kidneys.
