Eosinophilic Cystitis: Diagnosis and Treatment in Denmark

Abstract

Objective: The purpose of this study was to evaluate the incidence, diagnostic criteria and treatment of eosinophilic cystitis (EC) in Denmark during the period 1989-94. Material and methods: A questionnaire was sent to all Danish departments of surgery, urology and pathology. Results: Fifty-six cases of EC were diagnosed in the departments of surgery and urology, and 135 patients were diagnosed in the departments of pathology. The therapy was most often steroid instillation in the bladder or peroral antihistamines. Success rates of treatment were reported to be acceptable. Conclusion: The questionnaire confirmed that EC is a rare disease, which is often confused with other bladder diseases. We recommend strict histological criteria combined with clinical information when making the diagnosis of EC. Therapy is generally symptomatic. A diagnostic code number from the Danish Health Board is needed.
