Purina Veterinary Diets has launched Feline Urinary UR ST/OX™ to provide highly advanced nutritional support in the veterinary treatment and long term management of FLUTD.

Purina says that Feline Urinary UR ST/OX™ will help vets nutritionally support the management of three conditions most frequently associated with FLUTD in just one formula: dissolve struvite crystals, reduce the recurrence of both struvite and calcium oxalate uroliths and help treat feline idiopathic cystitis (FIC).

According to the company, the most advanced scientific methods of evaluation have been used to determine the efficacy of Feline UR ST/OX™, namely Activity Product Ratio (APR) and Relative Super Saturation (RSS) techniques. Rarely used, except in human science, APR is a dynamic and highly sensitive parameter. It is a more vigorous test than RSS and reflects more precisely the in vivo situation.

RSS assesses the likelihood of urolith formation by using measurements of urine pH, volume and mineral concentration. Urine APR goes further and calculates the ratio of urinary measurements before and after urine incubation with pure crystals (struvite or calcium oxalate.) APR is therefore able to more accurately predict the crystal evolution by assessing the cumulative influence of urine crystal growth promoters and inhibitors. Feline UR ST/OX™ is the first diet evaluated using both these parameters together. The results of the evaluation demonstrate a rapid dissolution for struvite and a reduction of recurrence for both struvite and calcium oxalate crystals.

FLUTD has a number of known risk factors including insufficient water intake and obesity. To date, the only interventions that have been repeatedly shown to increase water intake and urine volume are dietary modifications. In the management of FLUTD, raising water intake has three key benefits to decrease the concentration of various urolith-forming components in the urine, dilute inflammatory mediators and shorten the contact time of irritating substances with the bladder mucosa. Feline UR ST/OX™ dry formula has been shown to increase water intake by up to 20%, increase urine volume by up to 40% and consequently decrease urine specific gravity to below 1.045.

Feline UR ST/OX™ has also been specifically developed with moderate fat levels and optimal protein to help achieve and maintain ideal body condition thereby tackling obesity, another predisposing factor for FLUTD. With an exceptionally palatable formula, this new diet is available in both a wet and dry form.

Purina Veterinary Diets Feline Urinary UR ST/OX™ is available in the following pack sizes - 1.5 and 5kg and 195gr cans.
