History

4 year old female neutered Yorkshire Terrier with azotemia and specific gravity of 1.011.

Findings

The bladder is markedly enlarged and normal in opacity. The kidneys are not well visualized and appear small in size. Radiopaque sutures are visible in the abdomen and body wall. The liver, spleen, and gastrointestinal tract appear normal.

DDx

• Chronic renal disease (inflammatory, congenital)

Diagnosis

• Renal dysplasia

Interstitial fibrosis, glomeulosclerosis, undifferentiated mesenchyme, and fetal glomeruli were found on histopathology, consistent with renal dysplasia. Yorkshire Terriers are predisposed to this disease.

The kidneys were small and irregular on abdominal ultrasound with hyperechoic cortices and poor corticomedullary distinction.
