Eosinophilic cystitis in children:a report of 7 cases and literature review / 临床儿科杂志

ABSTRACT

Objective To explore the clinical and pathological features, diagnosis and treatment of eosinophilic cystitis in children. Method The clinical data of 7 patients with eosinophilic cystitis admitted from 2012 to 2016 were retrospectively analyzed, and the related literature were reviewed. Results The median age of the 7 patients was 9 years, and clinical manifestations were urgent urination, frequent micturition, odynuria, hematuria, abdominal pain and nocturnal enuresis. Ultrasonography and CT examination showed thickened bladder wall and space occupying lesions.All the 7 children received bladder biopsy, and pathology was consistent with eosinophilic cystitis. Six of them were cured after 2 months of drug therapy, and the other one was cured by repeated drug treatment for 1 year.All patients were followed up for 3 months to 4 years until the abnormal symptoms of voiding disappeared and the abnormal changes of bladder disappeared by imaging examination. Conclusion Eosinophilic cystitis in children is a benign lesion, having extremely similar clinical manifestations to bladder tumor. Without biopsy, the diagnosis of eosinophilic cystitis can also be made according to the clinical manifestation, laboratory examination and treatment effect. The treatment for this disease mainly includes hormone, antihistamine and anti-inflammatory drugs.
