Torção testicular em cão: relato de caso

Abstract

Testicular torsion is a rare urological emergency in dogs, which affects animals of any age and has no racial predisposition. Cryptorchid and monorchid dogs are more likely to develop this condition, as the ectopic position allows the organ to rotate on its own axis more easily. Senile dogs are also more susceptible to the alteration, since they are more affected by testicular neoplasms, and the development of these causes the affected testicle to increase in volume and become heavier, which favors rotation. Rotation of the testis on its horizontal axis causes torsion of the spermatic cord, which can cause venous return occlusion, infarction and testicular necrosis. This condition requires surgical intervention, and bilateral orchiectomy is the recommended surgical procedure. The present report aims to describe the case of a 12-year-old male Lhasa Apso canine with chronic intrascrotal testicular torsion. The patient was referred to veterinary care with suspected trauma to the scrotal region and, due to the progress of necrosis, clinical stabilization was chosen, followed by surgical excision of the scrotum and scrotal contents. The diagnosis was made through the histopathological examination of the excised structures, which ruled out the hypothesis of testicular neoplasm. Due to the low incidence of the disease in dogs with intrascrotal testes, reports are scarce, and this work is important because, although the indicated treatment is known and the prognosis is good, it is a urological emergency, which due to complications can cause the patient's death
