An outbreak of urolithiasis characterized by high mortality and emaciation in a flock of leghorn pullets is reported. The etiology was not ascertained. Other signs were swollen feet associated with articulate gout. Visceral gout, atrophy, or irregular hypertrophy of the kidneys were also observed. Many birds had one or both ureters enlarged with white uroliths. Microscopic lesions were urate granulomas, necrosis and loss of kidney parenchyma associated with tubular dilation, and edematous and fibrotic interstitium.
