Eosinophilic ureteritis? Regional ureteritis with marked infiltration of eosinophils

The case of a thirty-seven-year-old man with eosinophilic granuloma of the ureter is discussed. Preoperative x-ray studies disclosed distal ureteric regional stenosis and moderate hydronephrosis with small stone shadows. A segmental ureterectomy and vesicoureteral neostomy were performed. Pathologic examination of the removed specimen revealed markedly infiltrated eosinophils of the ureteric wall. The literature is reviewed and the causation of eosinophilic granuloma discussed.
