[Cytology of urine in eosinophilic cystitis. Apropos of 19 cases].

A retrospective, cytological study has been carried out on the urine of 19 patients diagnosed by means of an endoscopic biopsy as suffering from eosinophilic cystitis. The authors have assessed the erythrocytes, the urothelial cells and the inflammatory ones, by means of a percentage count on 1,000 of the latter. In all the cases there was found to be a percentage rate of polynuclear neutrophils of more than 90% as well as the constant presence of eosinophils although in a very limited percentage and the conclusion is reached that it is impossible to diagnose eosinophil cystitis by means of the cytological study of the urine alone.
