-- A cytooncologic test was performed in order to evaluate tumoral characteristics in the sediment of urine samples obtained from 210 bovine females, extensively or semiextensively bred in the province of Oxapampa (Pasco), area with a high presence of the bracken fern (Pteridium aquilinum) and a high prevalence of the Bovine Enzootic Vesical Haematuria (BEVH) disease. The processes of sample collection, centrifugation, urinary sediment collection, smear and fixation of the sample were performed in the field, while the Wright Test and the microscopic evaluation were done at the Laboratory of Histology, Embryology and Pathology at the School of Veterinary Medicine of the Universidad Nacional Mayor de San Marcos. The significant point in the detection of animals positive to this disease was mostly the finding of epithelial apaatypical cells with basophilic and polygonal cytoplasm. And with significant increasement of the nuclear-cytoplasm ratio favoring the nucleus. As an additional fact, it has been reported that most of the samples diagnosed as positive to the disease showed an increased number of apparently normal exfoliated urothelial cells accompanied by low number of mature erithrocytes. The present study demonstrated that using urinary cytooncology as a diagnostic method, 64 animals (30.47%) of the studied population show to be positive to the BEVH disease, thus demonstrating the usefulness of urinary cytooncologic evaluation, specially for the diagnose of the disease in its initial phases. In addition, the present work supports the BEVH report in our country and the need to determine a precocious and easy to develope “in the field” diagnostic method that may help monitoring and controling the disease in our environment. Therefore, urinary cytooncology could become the “golden” standard test to diagnose BEVH, although further research needs to be done in order to demonstrate the usefulness of this diagnostic tool. Key Words: Urinary Cytooncology, Bovine Enzootic Vesical Haematuria (BEVH), atypical cells, Bovine, Pteridium aquilinum (Pa).
