Abstract
Intensive consumption of dry feed of low quality, a sedentary lifestyle in animals, chronic infectious diseases of the urinary tract of cats lead to an increase of urolithia-sis. We have conducted analysis and evalua-tion of the veterinary diets "Brit Veterinary Diet Cat Struvite Grain Free" in cats with a stated diagnosis of struvite urolithiasis. The study was conducted in veterinary clin-ic LLC «Nikavet» in Saint-Petersburg and at the Department of pharmacology and toxicology of SPbGAVM in the autumn-winter period in 2019. The object of clinical and laboratory research were ten domestic cats of different sex, age and breed groups. During the clinical analysis of urine in most patients, urine pH was at the upper limits of the norm or exceeded it at an average of 0.5 units. The urine of all studied animals was muddy with a high density of 0.06 g/l, max-imum protein content was in the range of 3.0 g/l, at a rate of 0-0. 04. Such indicators in the urine as leukocytes, urobilinogen, ascorbic acid, epithelium, red blood cells exceeded the permissible limits. Duing urine sediment microscopy in three studied animals, crystals (struvites) occupied the entire field of view. Ultrasound examination of the bladder in animals showed a large and a moderate amount of hyperechoic suspension in the cavity, thickening of the mucous layer and clear differentiation of the layers of the bladder wall. After complex treatment with the use of veterinary diets at 15th day, the results of the analysis of urine from seven of the ten animals showed a good positive trend for the evaluated criteria (pH, protein, leukocyte count, uroliths and microflo-ra). At the end of 30 days from the begin-ning of the therapy performed in conjunc-tion with diet therapy, no deviations from physiological norms were detected during ultrasound diagnostics or according to the results of clinical analysis of urine.
