Eosinophilic cystitis: pleomorphic manifestations.

Because eosinophilic cystitis is rare, the authors present two cases of this inflammatory condition. In one, eosinophilic ureteritis presented as ureteral obstruction; this is only the second such case to be reported. The literature on eosinophilic cystitis is reviewed. The condition affects people of all ages and its cause is unknown. The clinical presentation varies, but hematuria is a constant feature with urinary frequency and dysuria being common. Management is also variable, ranging from treatment for symptoms only to aggressive surgical therapy.
