RESUMEN
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

RESUMEN
Introdução: Arritmias cardíacas ocorrem em mais de 40% dos animais com síndrome dilatação e vólvulo gástrico (DVG). O ritmo idioventricular acelerado consiste em um ritmo ventricular com frequência cardíaca entre 60 e 100 bpm. A taquicardia supraventricular consiste em uma rápida arritmia originária do tecido supraventricular. O objetivo deste trabalho é relatar a ocorrência de ritmo idioventricular acelerado e taquicardia supraventricular, observados em um cão com síndrome DVG.Caso: Um canino da raça Fila Brasileiro, macho, quatro anos de idade, foi atendido apresentando um quadro de distensão abdominal com evolução de cerca de duas horas. Ao exame clínico, o animal apresentou taquicardia, taquipnéia e aumento de volume abdominal compatível com acúmulo de gás. Após falha na tentativa de sondagem para a descompressão gástrica, optou-se por tratamento cirúrgico. O estômago e o baço estavam dilatados e rotados em 180 no sentido horário. Foi realizado reposicionamento manual destes órgãos, gastrotomia para remoção do conteúdo gástrico, invaginação de região de coloração alterada do estômago e gastropexia. A monitoração eletrocardiográfi ca durante o procedimento cirúrgico não evidenciou alterações. No período pós-operatório, o paciente foi submetido a exames eletrocardiográfi cos duas vezes por dia, durante cinco dias. No período entre 12 e 48 horas após o procedimento cirúrgico,
