Carcinoma de células transicionales en la vejiga de canino hembra: Reporte de Caso.

Abstract

The objective of this work is to present the case of a 10-year-old female Shih Tzu breed dog, who was admitted to general consultation on January 5, 2022, because her owners reported that the animal was listless, he did not eat as before, he had difficulty urinating, he urinated small amounts and they observed drops of blood. A thorough and physical examination of the patient was carried out, the owners were recommended to carry out hematological tests, partial urine tests, ventro-dorsal and latero-lateral radiographs of the abdomen, cystoscopy and histopathology; Through these tests, a diagnosis of transitional cell carcinoma in the bladder was obtained. His treatment initially consisted of patient stabilization, diet change, symptom therapy, to continue with chemotherapies using Mitoxantrone and Piroxicam ®, in order to improve the patient's well-being and quality of life. Transitional cell carcinoma, also known as urothelial carcinoma, is perhaps the most common malignant tumor in the urinary bladder of dogs, with a higher incidence in females; It constitutes the most frequent cancer with presentation in canines in the urinary tract, caused by a malignant neoplasm, generally located in the bladder trigone, generating non-specific symptoms and signs such as stranguria, hematuria, frequency and urinary incontinence; the cause of this disease is non-specific, it can be caused by etiological, endogenous and iatrogenic factors, generating an alteration in urinary functionality and in turn interfering with the well-being of those who suffer from it (Martins, et al. 2012).
