Abstract: | Clinical observations were performed on 5 cases of eosinophilic cystitis that had been diagnosed by our criteria. In all 5 cases some kind of allergic diseases was found. General urinalysis did not show any definite tendency, but eosinophils in urine were found in 4 cases. Cystoscopy revealed only chronic inflammation and submucosal hemorrhage in 4 cases, and the other case showed ulcerative changes. A positive to immediate skin reaction was seen in 2 of the 4 cases. IgE RAST was positive for mite, house dust and mugwort in 1 of these 2 cases. In this case immediate allergic reaction was suspected as part of the cause of the cystitis. |
