A 4-year-old castrated male Burmese cat was evaluated because of nonregenerative anemia (PCV, 20%) and was found to have renal failure. Renal ultrasonography revealed bilateral hydronephrosis. Antegrade pyelography of the right kidney failed to indicate obstructive disease. Necropsy and histologic examination of the ureters revealed a markedly stenotic lumen and massive fibrosis of the mucosa. An etiologic agent could not be found.
