RESUMO
BACKGROUND: Cytoscopic-guided laser ablation (CLA) is a technique that can be used to correct intramural ectopic ureters (EUs) in dogs. HYPOTHESIS/OBJECTIVES: To describe clinicopathologic, imaging, and cystoscopic findings in dogs undergoing CLA for intramural EU correction, and whether any of these findings are associated with continence outcomes. ANIMALS: Thirty-one client-owned dogs undergoing CLA between 2009 and 2019. METHODS: Retrospective cohort study. Data collected from medical records included signalment, clinical findings (including continence score at presentation), clinicopathologic findings (serum biochemistry profile, urinalysis, and urine culture results before CLA), ultrasonography, and cystoscopy findings. Follow-up information was collected at 1 day to 1 week, 1 week to 1 month, and at >1 month time points after CLA. Final continence score was determined based on this follow-up information. Multiple logistic regression was used to determine factors that were associated with final continence score. RESULTS: Median continence score of dogs at initial evaluation was 2 (range, 2-4). Median continence score after CLA alone was 3 (range, 1-5). Seventeen of 31 (54.8%) dogs received adjunctive medical management after CLA. Median continence score after CLA with or without adjunctive medical management was 5 (range, 1-5). Overall, 67.7% of dogs were considered continent after CLA with or without adjunctive medical management. No preoperative or perioperative factors were found to be associated with final continence score. CONCLUSIONS: Cystoscopic-guided laser ablation for intramural EU in female dogs provides improvement in incontinence. Dogs remaining incontinent after CLA may improve with adjunctive medical management. Surgical management is required to manage incontinence in dogs with extramural EU.

BACKGROUND: Hemosiderophages can be found in bronchoalveolar lavage samples and have been reported in association with a wide range of respiratory and cardiovascular disorders in cats and humans. OBJECTIVES: This study aimed to retrospectively evaluate the presence of hemosiderin in canine and feline bronchoalveolar lavage (BAL) samples. It also aimed to examine the association of BAL hemosiderin with signalment, clinical signs, and historical disease prior to BAL, with prior transthoracic fine-needle aspiration (FNA), with bronchoalveolar lavage duration, and with cytologic interpretation. METHODS: The medical records of dogs and cats with respiratory disease that underwent BAL between 2007 and 2016 were reviewed. Appropriate medical information and BAL results were available from 171 dogs and 34 cats. Cases were assigned to four disease categories based on BAL cytologic findings: pneumonia, inflammatory disease, neoplasia, or normal airways. The degree of hemosiderosis was classified based on a semi-quantitative scoring scale. Exact logistic regression analysis was used to evaluate the relationship between risk factors and the presence of BAL hemosiderosis on cytology. RESULTS: Hemosiderin was identified in 13/171 (7.6%) canine samples and 18/34 (52.9%) feline samples. Cats were 13.33 times more likely to have pulmonary hemosiderosis on bronchoalveolar lavage cytology compared with dogs (P < 0.001). Increased respiratory rates, prolonged bronchoalveolar lavage times, concurrent transthoracic FNAs, and cytologic diagnoses were associated with an increased risk of hemosiderosis in dogs. No specific risk factors associated with pulmonary hemosiderosis in cats were identified. CONCLUSIONS: Hemosiderosis is more common in BAL samples from cats than from dogs and is associated with a diverse range of disease conditions.

OBJECTIVE To compare bronchoalveolar lavage (BAL) accomplished by use of a bronchoscopic (B-BAL) and a nonbronchoscopic (NB-BAL) technique in healthy cats. ANIMALS 12 healthy cats. PROCEDURES Two BALs were performed in a randomized order 2 weeks apart in each cat. Cats were anesthetized, and a 2.9-mm fiberoptic bronchoscope (B-BAL) or 8F red rubber catheter (NB-BAL) was wedged in a bronchus. Two 5-mL aliquots of saline (0.9% NaCl) solution were infused into the left and right caudal lung fields and aspirated manually with a 20-mL syringe. Proportion of BAL fluid (BALF) retrieved, depth of wedging, and anesthetic complications were recorded. Total nucleated cell count, differential cell count, and semiquantitative scores of cytologic slide quality were determined for all BALF samples. Results were compared with ANOVAs and Wilcoxon signed rank tests. RESULTS Proportion of retrieved BALF and depth of wedging were significantly greater for B-BAL than NB-BAL. Differential cell counts and cytologic slide quality did not differ significantly between techniques. Complications included transient hemoglobin desaturation (24/24 [100%] BALs) and prolonged anesthetic recovery time (4/24 [17%] BALs). Anesthetic recovery scores did not differ significantly between techniques. CONCLUSIONS AND CLINICAL RELEVANCE Results indicated that NB-BAL was noninferior to B-BAL with regard to ease of performance, anesthetic variables, and cytologic slide quality for cats without clinical respiratory tract disease.
