Benign ureteral obstruction in cats: Outcome with medical management.

BACKGROUND: Limited information is available regarding the outcome of medical management (MM) of benign ureteral obstruction in cats (BUO). HYPOTHESIS: Describe clinical characteristics and outcome of MM of BUO. ANIMALS: Seventy-two client-owned cats with 103 obstructed kidneys. METHODS: Medical records of cats diagnosed with BUO between 2010 and 2021 that received >72 hours of MM were retrospectively reviewed. Clinical data, treatment, and outcome were reviewed. Outcome was classified as success, partial success, or failure based on ultrasound findings. Factors associated with outcome were assessed. RESULTS: Seventy-two cats with 103 obstructed kidneys were enrolled. The causes of obstruction were uroliths in 73% (75/103), strictures in 13.5% (14/103), and pyonephrosis in 13.5% (14/103) of affected kidneys. Median serum creatinine concentration at presentation was 4.01 mg/dL (range, 1.30-21.3 mg/dL). Outcome after MM was considered a success in 30% (31/103), partial success in 13% (13/103), and failure in 57% (59/103) of kidneys. Success was reported in 23% (17/75) of kidneys with uroliths, 50% (7/14) with pyonephrosis, and 50% (7/14) with strictures. Median time to a successful outcome was 16 days (range, 3-115 days). Distal and smaller uroliths (median length, 1.85 mm) were significantly associated with success (P = .05 and P = .01, respectively). Median survival times were 1188 days (range, 60-1700 days), 518 days (range, 7-1812 days), and 234 days (range, 4-3494 days) for success, partial success, and failure, respectively. CONCLUSIONS AND CLINICAL IMPORTANCE: We found a higher success rate for MM of BUO than previously reported. Smaller distal uroliths (<1-2 mm) were more likely to pass.

Feline urinary incontinence: a retrospective case series (2009-2019).

OBJECTIVES: The objective of this retrospective study was to describe the feline population presented for urinary incontinence at a veterinary teaching hospital between 2009 and 2019, with a particular focus on cats with a non-neurologic underlying cause. METHODS: The medical records of cats diagnosed with urinary incontinence were retrospectively evaluated. Signalment, clinical presentation, results of diagnostic tests, diagnosis of the underlying cause and treatments were recorded. When information was available, outcome was recorded and follow-ups divided into three time frames (0-1 week, 1 week to 3 months and >3 months). RESULTS: Thirty-five cats were presented with urinary incontinence. Of these, 18 cats with complete medical records presented urinary incontinence of non-neurologic origin. The most common clinical signs at presentation were urine leakage while resting (12/18), urine-soiled perineum (8/18), urine dribbling (8/18) and no spontaneous micturition (5/18). The most common underlying cause was urethral obstruction (67%; 12/18), with a majority due to urethral strictures (58%; 7/12). Other causes were suspected inflammation (2/12), neoplasia (1/12), urolithiasis (1/12) and foreign body (1/12). In 8/10 cats in which it was performed, cystoscopy and contrast cystourethrography were the methods that led to the diagnosis. Twelve cats with urethral obstruction underwent interventional procedures, resulting in complete resolution of incontinence in 7/12 and improvement in 1/12. Urinary tract infection was a common complication after 3 months (4/18). CONCLUSIONS AND RELEVANCE: When incontinence of non-neurologic origin is suspected in a cat, urethral obstruction should be considered. Advanced imaging studies (cystoscopy and contrast studies) are useful for diagnosis. A good prognosis was reported in cats undergoing interventional procedures with no long-term treatment.

Questionnaire-based survey on distribution of canine ocular thelaziosis in southwestern France.

The distribution of Thelazia callipaeda, commonly known as "oriental eyeworm'', has been considered for a long time to be confined to the former soviet Republics and Asia where the nematode causes infections in domestic and wild carnivores, rabbits and sometimes humans. However, since 2000, thelaziosis has been diagnosed in dogs and sometimes in cats from a growing number of European countries, including France. In 2006, a survey demonstrated that many autochthonous cases of canine thelaziosis were present in the department of Dordogne (southwestern France) in three hyperenzootic counties where strawberry production was predominant. The objective of the present study was to obtain an updated evaluation of the enzootic occurrence of T. callipaeda in France. In April 2016, an electronic questionnaire was sent to 1670 veterinary clinics from 24 French departments of southwestern France. Among 279 responses, 97 veterinary clinics reported cases of canine thelaziosis during the last 12 months. Most of them (72/97, 74.2%) reported a limited number of cases. Two veterinary clinics in previously-identified hyperenzootic counties of Dordogne reported the higher incidence (50 and 68 new cases annually). Noteworthly, two clinics located in another department (Landes) also reported many autochthonous cases (30 cases annually) demonstrating the existence of new enzootic foci. The present investigation confirmed that Dordogne is still an enzootic area of ocular thelaziosis and that the disease is spreading in new areas of southwestern France since a decade.
