Canine perineal hypospadias / Hipospadia perineal canina

Background: Hypospadias is a congenital malformation, rarely reported in dogs, caused by a failure of the urogenital folds to fuse during fetal development resulting in incomplete formation of the penile urethra. The inadequate production of fetal androgens is believed to be the etiology of this condition. It is characterized by urethra and corpus spongiosum deficiency, often accompanied by penile underdevelopment, and cryptorchidism. Classification is based on anatomical location of the urethral meatus opening as glandular, penile, perineal, anal, and scrotal. The aim of this paper is to report a case of perineal hypospadias in a male, six-month old French bulldog, describing the therapeutic approach. Case: A six month old male French bulldog, weighing 14.3 kg, was presented for a veterinarian appointment at the Department of Veterinary Medicine (Federal University of Sergipe, Brazil) due to a prolapsed nictitans gland and abnormalities of its genitalia. The medical records included recurrent urinary infection, presence of ectoparasites (thick) and ehrlichiosis, previously treated with doxycycline for 28 days (5 mg/kg/BID). During physical examination, the patient was bright and alert showing a good overall body condition. Temperature, pulse, respiration, thoracic auscultation and lymph nodes were within normal limits. Abdominal palpation was unremarkable. Inspection of the [...]
