RESUMO
Background: Ureteral ectopia is a congenital abnormality of the terminal segment of one or both ureters, in which the ureteral orifi ce is located distal to the trigone of the bladder. Ureteral ectopia results from dysembryogenesis of the ureteral bud due to its abnormal positioning along the mesonephric duct. It is frequently associated with other congenital anomalies of the lower urinary tract as urethral sphincter dysfunction, hydroureter and hydronephrosis. Ectopic ureters are classifi ed into two categories: extramural and intramural. Extramural ectopic ureters completely bypass the urinary bladder without anatomic attachment, opening directly into the urethra, vagina or uterus. Continuous or intermittent urinary incontinence is the most frequently reported clinical symptom associated with ureteral ectopia, and it is far more frequent in young bitches than in male dogs. Repositioning the distal segment of the ureter and ureteral orifi ce directly into the bladder may restore urinary continence throughout neoureterocistostomy.Case: A 3-month-old female poodle weighting 4 kg was referred to the Teaching Veterinary Hospital of the Federal University of Rio Grande do Sul (HCV-UFRGS), State of Rio Grande do Sul, Brazil, due to urinary incontinence, dysuria and severe vulvar pyodermatitis since it was 9 weeks old. Normal posturing and voiding of urine did occur, although only sm

RESUMO
Background: Endocrine tumors are considered rare in veterinary medicine. Studies suggest that only one or two per cent of these are primary neoplasms of the adrenal glands. Concerning the histological classifi cation of these masses, the most frequently occurring malignant neoplasms in dogs are adenocarcinomas and pheochromocytomas and, among the benign tumors, adenomas are the most common. Although much rarer, hemangiomas, myelolipomas, among others, may also occur. Dogs with this kind of neoplasm could be asyntomatic or show gastrointestinal signs, pain and urinary tract infection. Adrenalectomy is the treatment of choice and could be curative in most cases. This paper reports a case of two concurrent benign, rare adrenal neoplasms in a dog, emphasizing the clinical signs, diagnosis and treatmentCase: An eight-year-old, male castrated Chow-chow, weighting twenty one kilograms, was admitted at the Veterinary Teaching Hospital of the Federal University of Rio Grande do Sul (UFRGS) with a history of intermittent vomiting and diarrhea since it was a puppy. Because of the chronicity and nonspecifi c signs, additional tests were requested. Abdominal ultrasonography showed a round mass, measuring approximately 3.7 cm x 3.2 cm, suggesting a neoplasm. Blood pressure was measured and the mean value was 152 mmHg. Laboratory tests included a complete blood count, albumin (31.62 g/L), ala
