Diagnosis of urinary tract infection by urinalysis, ultrasonography and quantitative urine culture

This study was conducted to diagnose urinary tract infection from the dogs presented to the Veterinary College Hospital during the period of 6 months by urinalysis, ultrasonography and cultural examination and to determine the antimicrobial resistance profile of the urine samples. 72 dogs were presented to Veterinary College Hospital, Bengaluru with clinical sign suggestive of UTI among that 65 urine samples having more than 103 cfu/ml on quantitative urine culture were considered for study. Urinalysis and sonographic changes were evaluated. Urine culture was carried out to isolate bacteria from urine samples and to know quantitative bacterial count in the sample. Increased frequency of urination, straining while passing urine, hematuria and oliguria were the common signs observed in dogs. Change in the colour, turbidity, proteinuria, pyuria, haematuria and bacteriuria were noticed on urine analysis. Thickening of the bladder (> 3 mm), hyperechoic calculi in lumen and sludge in the lumen were noticed in ultrasonography.
