However, since bacteria are more difficult to detect than white cells, pyuria may appear to be unassociated with low numbers of bacteria (Table 2). Polyuria in dogs is an abnormal increase in urine, which can cause more frequent urination, a higher volume of urine to come out during urination, or both. Persistent Urinary Tract Infections and Reinfections in 100 Dogs (1989–1999) M. Alexis Seguin, Shelly L. Vaden, Craig Altier, Elizabeth Stone, and Jay F. Levine ... pyuria were grouped as 0–5 (normal), 5–50, and .50 cells per high-power field. 2) A positive urine culture in the absence of pyuria should arouse suspicion that the bacteria are contaminants. Therefore, it is important to evaluate fresh urine sediment to determine the presence or absence of pyuria in dogs and cats. The results were: specific gravity = 1.035; pH = 6.5; protein = 1+; leukocyte esterase = negative; RBC in sediment = 2 to 4 per 450X; white cells in sediment = 5 to 10 per 450X. The first group of tests performed includes urinalysis, urine culture, and bladder palpation. A voided urine sample was obtained from a 12-year old spayed female Dachshund as part of an annual evaluation of health status. Screening for proteinuria has diagnostic value in the initial detection and confirmation of proteinuric renal disease. Large numbers of white blood cells in voided urine samples can indicate an active inflammation somewhere along the urogenital tract. Dogs can also develop bacterial prostatitis, paraprostatic cysts, and prostatic neoplasia. Dogs and cats can get one of two different types of pyometra infection. The site(s) of this UTI cannot be determined on the basis of available information. reported that uNGAL concentration significantly increased in nonazotemic dogs with UTI when compared to dogs with negative urine culture results. The name of this disease is Latin for “pus-uterus” and describes a life threatening uterine infection that most typically affects older, intact (or unspayed), female dogs. The inflammatory lesion may or may not be associated with infectious agents. The most common clinical sign is hematuria or blood in the urine. An underlying cause for the recurrent lower UTI could not be found. We elected to repeat the urinalysis on a sample collected by cystocentesis. A survey by abdominal x-ray and ultrasound imaging also may be used if your veterinarian has not been able to settle on a conclusive diagnosis. All rights reserved. Bacterial culture of a urine sample collected by cystocentesis three days later resulted in no growth, although pyuria was still present. 's study, specificity of uNGAL was low (76%) and the authors supposed that the lack of specificity of uNGAL might be due to noninfectious pyuria that … Enterococcal UTI in dogs is associated with comorbidities including neurologic dysfunction, endocrinopathies, incontinence, corticosteroid administration, urolithiasis, neoplasia, LUT anatomic abnormalities, chronic kidney disease, and urinary catheterization. Pyuria is a condition in which excess white blood cells, or pus, are present in the urine. No other abnormalities were detected. In this context, it becomes readily apparent that there is no absolute cut off point between upper numbers of "normal" white cell numbers and lower limits of "abnormal" white cell numbers. 1 To date, there is a lack of case control studies that identify risk factors for the development of Enterococcus spp. With these factors in mind, what would you do next? visible only with a microcsope ... or idiopathic (dogs) common causes of canine LUTD without obstruction. Likewise, the alkaline pH of urine would enhance white cell disintegration. Your veterinarian will set up a schedule with you so that your dog's progress can be followed. But half of all cancers are curable if caught early, experts say. 100 –102 Cranberry extracts have demonstrated in vitro efficacy in preventing bacterial attachment to the uroepithelium of dogs and cats in a dose-dependent way, but evidence of a clinical effect is inconsistent.
