ResumoA uretrostomia é técnica cirúrgica utilizada em casos de obstrução parcial ou total da uretra, e na abordagem laparoscópica pode ser uma opção de tratamento. Devido à escassez de estudos envolvendo essa técnica, este trabalho relata o caso de uretrostomia pré-púbica videoassistida (laparoscópica híbrida) em um felino com estenose uretral. O paciente de cinco anos de idade apresentando histórico de doença do trato urinário inferior dos felinos (DTUIF) recorrente, havia sido submetido a uretrostomia perineal há dois anos e nove meses. Depois desse procedimento, o paciente passou por mais quatro cirurgias corretivas sem sucesso. Após realização de exames laboratoriais (hemograma e bioquímicos) e de imagem, o animal foi submetido a uretrostomia pré-púbica laparoscópica híbrida, obtendo-se sucesso terapêutico e possibilitando ao paciente adequada qualidade de vida. Conclui-se que esta técnica é viável e segura em gatos, tornando-a uma possível escolha de tratamento cirúrgico para estenose uretral.

Due to the scarcity of studies involving the technique, this paper reports the case of laparoscopic-assisted pre-pubic urethrostomy (hybrid laparoscopic) in a cat with urethral stricture. A five-years-old cat presenting recurrent feline lower urinary tract disease (FLUTD) had undergone to perineal urethrostomy two years and nine months ago. After this procedure, the patient underwent another four corrective surgeries without success. Laboratory tests (blood count and biochemical) and image diagnosis were realized. The patient was subjected to laparoscopic-assisted pre-pubic urethrostomy and it was achieved therapeutic success and adequate patient quality of life. It is concluded that this technique is feasible and safe in cats, making it a possible choice of surgical treatment for urethral stricture.

Background: Prostatic cancer is a rare condition in cats but should be included as a differential diagnosis whenever middleaged cats present lower urinary tract signs, such as dysuria and hematuria. Abdominal ultrasound can indicate the disease, but fine-needle aspiration cytology and histopathology are necessary to establish the neoplastic origin and the therapeutic plan. Because of the limited data, no standard-of-care treatment or prognostic information exists in cats with prostate carcinoma. This report describes the clinical signs, diagnosis and surgical approach in a case of prostatic carcinoma in a cat. Case: A 6-year-old, intact male, domestic short-haired cat was presented with a 3-day history of dysuria, hematuria, inappetence, constipation, lethargy and prostration. On physical examination, the cat was in a very poor general condition and abdominal palpation revealed firm mass located caudally to the urinary bladder. The urinary bladder presented high repletion degree, while the large bowel was distended and presented soft faecal content. Blood count, serum biochemistry and urinalysis showed neutrophilic leukocytosis, hypoalbuminemia and high creatinine level, and severe hematuria, respectively. Abdominal ultrasound showed a mass located in the prostatic area with hypoechogenic and slightly heterogeneous parenchyma, measuring 3.3 x 3.0 cm. Echo-guided trans-abdominal fine-needle aspiration of the prostate was performed. Microscopically, the cells were round with basophilic cytoplasm, and had round to ovoid nuclei, dense chromatin and prominent nucleoli. Some cells were binucleated and mild anisocytosis and marked anisokaryosis were documented. These findings were compatible with malignant prostatic neoplasia. After initial clinical stabilization, the patient underwent an exploratory laparotomy for tumor resection. Cystotomy followed by pubic osteotomy was performed to access the tumor. Urethral anastomosis was necessary due to adherence of the neoplasm to adjacent structures. However, the patient died during the immediate postoperative period. No complications related to surgery were observed at necropsy. Tissue specimens were collected and stained by hematoxylin and eosin. Prostatic carcinoma was confirmed by immunohistochemistry tests using streptavidin-biotin-peroxidase complex method, and primary antibodies against vimentin, cytokeratin AE1/AE3 and 7. Discussion: Prostatic neoplams are rare in cats and clinical signs are suggestive of lower urinary tract disease, such as dysuria and/or hematuria, associated with tenesmus. Abdominal or rectal palpation seems to be essential to detect the prostatic enlargement. Ultrasound imaging was more sensitive than radiography, since it brings more information about structure, size, form and prostatic internal architecture. The patient's serum creatinine value above the normal range for cats indicated partial urethral obstruction, due to neoplastic concentric growth. Echo-guided trans-abdominal fine needle aspiration cytology was an effective method to confirm n...

ObjectivesTo quantify the physical activity levels in dogs with cranial cruciate ligament rupture before and after lateral fabellar suture stabilisation surgery.Materials and MethodsSeventeen dogs (mean weight, 12.3±5.1 kg) with unilateral cranial cruciate ligament rupture were fitted with an accelerometer for seven consecutive days at four different time points: before surgery (T0), one (T1), three (T3) and six (T6) months after surgery. The total activity and times spent in sedentary activity, light to moderate activity and vigorous activity were recorded by the accelerometer, and preoperative and postoperative data were compared. At all time points, dogs underwent clinical evaluations (lameness score, stifle pain score and thigh circumference) and their owners were asked to respond to questionnaires to subjectively score the physical activity and quality of life of the dogs.ResultsAt the four time points, the dogs spent between 21.2 and 21.4 hours on sedentary behaviour, 2.3 and 2.5 hours performing light to moderate activity, and 13 to 15 minutes performing vigorous activity. There was no increase in physical activity variables or decrease in sedentary behaviour over time. Lameness scores, pain score and dogs' quality of life improved significantly during the postoperative period. At T6, 17 (100%) of 17 dogs presented no lameness, 16 (94%) of 17 dogs presented no stifle pain, 16 (94%) of 17 owners rated the quality of life as very good and excellent, and 16 (100%) of 16 owners reported a total return to normal activity levels.Clinical SignificanceThe clinical recovery after extracapsular stabilisation of the stifle joint was not associated with a spontaneous increase in physical activity or a decrease in sedentary behaviour.

Highlights The training regimen influenced the night time physical activity of athlete horses. Thoroughbred racing horses trained on continual days had lower physical activity in the night time than those trained on intermittent days. Accelerometry is a good tool for measuring horse movements in box stalls, and there is an area for further studies with the use of accelerometers in equines.
