RESUMO

A 7-year-old male neutered, 6.5 kg, Maltese breed dog was referred with a history of dysuria after undergoing two cystotomies to remove calcium oxalate uroliths. Survey radiographs were inconclusive. Excretory urography allowed visualization of two filling defects in the cranioventral urinary bladder region. Ultrasonography showed urinary bladder sediments, a diffusely thickened wall, and two circumscribed intramural/intraluminal structures with an anechoic interior and a smooth and regular surface. The cystoscopic diagnosis was urinary bladder abscesses and urine cultures were positive for Escherichia coli. Antimicrobial/anti-inflammatory therapy was started with good clinical outcomes and negative culture after 21 days.

RESUMO

Renal ectopy is a rare condition in small animals, characterized by abnormal positioning of one or both kidneys. It is classified as simple or crossed and, according to its localization, being diagnosed in an incidental way in pets because of its nonspecific and many times asymptomatic clinical presentation. Imaging exams such as ultrasound, radiography, and excretory urography may close the diagnosis. This paper reports a case of simple, unilateral, renal ectopy, in a three-year-old male Lhasa Apso dog, with no clinical or laboratory findings consistent with renal disease, in which the ectopic condition, together with shape, rotation, and vascular abnormalities, were incidental findings during abdominal ultrasound examination.(AU)

A ectopia renal é uma condição rara em pequenos animais, caracterizada pelo posicionamento anormal de um ou ambos os rins. É classificada como simples ou cruzada e de acordo com a sua localização, sendo diagnosticada de forma inci-dental nos animais de companhia em decorrência de sua apresentação clínica inespecífica e muitas vezes assintomática. Os exa-mes de imagem como ultrassonografia, radiografia e urografia excretora podem fechar o diagnóstico. Esse trabalho relata um caso de ectopia renal simples e unilateral em um cão macho da raça Lhasa Apso de três anos de idade, sem apresentações clí-nicas e laboratoriais condizentes de doença renal, no qual o rim ectópico associado a anomalias de forma, rotação e vasculares foram achados incidentais durante o exame ultrassonográfico abdominal.(AU)

RESUMO

Background: Ureteral ectopia (or ectopic ureter) is a congenital anomaly of the urinary system in which the ureter insertsanywhere other than the vesical trigone. This anatomical change may have unilateral or bilateral involvement. The mostevident clinical sign, occurring mostly in females, is urinary incontinence, however in some cases the condition may progressto nephritis and dilation of the renal pelvis. The diagnosis is established through imaging, and definitive treatment requiressurgical approach. The present study reports a case of ureteral ectopia in a dog which was diagnosed by ultrasound andcontrast radiography (excretory urography) and successfully treated by neoureterostomy.Case: A 10-month-old female American Pit Bull Terrier was attended at the Veterinary Hospital of the Federal Rural University of the Semi-Arid (UFERSA), in Mossoró, RN. Her owner reported incontinence of dark, malodorous urine sincebirth as the chief complaint. After clinical examination, cystitis was suspected, and a complete blood count, urinalysis,and abdominal ultrasound was requested. The blood count and creatinine were within the reference values. The presenceof struvite crystals were found on urinalysis. Ultrasound examination revealed a tortuous, dilated right ureter from therenal pelvis to the urinary bladder; no uroliths were identified as a cause of potential obstruction, but the ipsilateral kidneyshowed increased cortical echogenicity, loss of corticomedullary definition, and moderate pelvic dilation. These findingssupported a presumptive diagnosis of ectopic ureter. For the purpose of confirming this suspicion, excretory urography wasperformed, revealing unilateral ureteral dilation and radiopaque contrast uptake following the path of the urethra. Once thediagnosis was confirmed, surgery was performed to correct the ureteral ectopia using the standard...(AU)

RESUMO

A 3 year old female feline of mixed breed was sent to the diagnostic imaging sector under suspicion of bleeding due to ovariohysterectomy. An abdominal ultrasonography was performed to confirm the initial suspicion. However, no signs of bleeding were found, instead it was observed that the left renal silhouette had two pelvises and was elongated and larger than normal. The right kidney was not found. Excretory urography was requested to evaluate the condition of the ureters. The final diagnosis was crossed renal ectopia with fusion in an asymptomatic cat with no changes in renal function.(AU)

Uma gata, sem raça definida, com três anos de idade, foi encaminhada para o setor de diagnóstico por imagem sob suspeita de hemorragia devido à ovário-histerectomia. Foi realizada ultrasonografia abdominal para confirmar a suspeita inicial, mas nenhum sinal de hemorragia foi encontrado; visibilizou-se, entretanto, a silhueta renal esquerda alongada, com presença de duas pelves. O rim direito não foi encontrado. Solicitou-se exame de urografia excretora para avaliação de ureteres. O diagnóstico foi de ectopia renal cruzada com fusão em um felino assintomático e sem alterações na função renal.(AU)
