Ureter ectópico extramural em um cão Labrador Retriever: relato de caso / Ectopic ureter extramural in a Labrador Retriever dog: a case report

A ectopia ureteral é uma enfermidade congênita que se caracteriza quando um ou ambos os ureteres apresentam-se inseridos fora do seu local anatômico, com a inserção ocorrendo no útero, no colo da bexiga, na uretra ou na vagina, devido a uma diferenciação anormal dos ductos mesonéfricos e metanéfricos. Nos machos, a inserção pode ocorrer também nos ductos deferentes e na próstata. A incontinência urinária é o sinal clínico mais comumente associado ao ureter ectópico. O presente relato descreve um caso de ureter ectópico extramural unilateral, em um cão da raça Labrador Retriever de sete anos de idade, corrigido cirurgicamente, e mostra a importância dos exames radiográfico contrastado e ultrassonografia.(AU)

Ureteral ectopia is a congenital disease that is characterized when one or both ureters are shown inserted outside their anatomic site, with the possible insertion in the uterus, bladder neck, the urethra or vagina due to abnormal differentiation of ducts mesonephrics and metanephrics. In males the insertion can also occur in the vas deferens and prostate. Urinary incontinence is the most common clinical sign associated with ectopic ureter. This report describes a case of unilateral extramural ectopic ureter in a dog of the Labrador Retriever breed at seven years old surgically corrected, and shows the importance of contrast radiographic examination and ultrasound.(AU)

Carcinoma de células de transição da uretra com metástases cardíaca e pulmonar em cão

A case of urethral carcinoma in 15-year-old mongrel male dog is described. Signs of dysuria, urethral obstruction, tenesmus, pain and cough were mentioned. Clinically, the animal was undernourished and showed signs of pain and bladder repletion during the palpation of the abdominal region. Other complementary exams were made such as routine urinalyses, X-ray, ultrassonography and measurement of blood urea and creatinine. Macroscopically, the mucous membrane of pelvic urethra was somewhat irregular, due to the presence of several small white irregular and ulcerated nodules of imprecise boundaries. Similar nodules were found in the lungs and heart. Histologically, transitional cell carcinoma of urethra with metastasis to lung and heart was detected.

Uso de cetoanálogo na terapia da insuficiência renal canina

The efficacy of keto acids and essential amino acids on a two-year-old female dog, Labrador, suffering from Leishmaniasis and acute renal failure was evaluated by clinical and laboratorial analyses based on urea and creatinine dosages. An improving in the animal general condition and an increasing in the appetite, activity and weight gain, were observed and favorably contributed to the treatment of the primary disease. Ketoanalogueswere oraly administered during 76 days and the levels of urea and creatinine remained within acceptable limits, even after this period of time. Ketoanaloguescontributed positively for the treatment of acute renal failure and appears to be an important alternative for the leishmaniasis treatment.
