Acidification of pet foods also resulted in an increased incidence
of calcium oxalate uroliths / stones.
• Clinically proven to produce a Calcium Oxalate Relative Supersaturation of < 5 in dogs and cats, which has been shown to limit the formation
of calcium oxalate uroliths.
Demonstrating that a diet with controlled levels of dietary calcium and oxalate reduces the risk
of calcium oxalate urolith recurrence in dog.
Not exact matches
The most common cause
of obstruction is a urethral plug, which consists
of mineral crystals (e.g., struvite,
calcium oxalate), white blood cells, red blood cells, protein (mucus), and epithelial cells.5 The underlying cause
of urethral plugs is unknown; however, plugs have been linked to struvite crystalluria — suggesting that diet may play a role — and idiopathic cystitis.6 Other causes
of urethral obstruction include urethral edema and spasm associated with lower urinary tract inflammation and pain.7
Uroliths, neoplasms, and urethral strictures can also lead to urethral obstruction; however, they are reported less frequently than other causes.5
Uroliths: These are crystals (
calcium oxalate, struvite) that form in the urinary tract and black the flow
of urine.
The second most common type
of urolith is
calcium oxalate.
Rate and frequency
of recurrence
of uroliths after an initial ammonium urate,
calcium oxalate, or struvite
urolith in cats.
Commercial food changes, unfortunately, have led to more surgeries to remove
calcium oxalate stones, for this type
of urolith requires surgical intervention.
Dry format: Dissolve pure struvite

Current thinking suggests that
calcium oxalate uroliths can form across the physiological urine pH range indicating that control
of urine pH is not a critical factor in managing and reducing the risk
of calcium oxalate formation in dogs (Stevenson and Rutgers 2006).
This study demonstrated that feeding a high - moisture, moderately - acidifying diet with controlled levels
of calcium and
oxalate to dogs that have formed
calcium oxalate uroliths had beneficial effects on urine parameters and helped prevent recurrence for the 12 months they were under observation.
Calcium oxalate uroliths are particularly prevalent in small breed male dogs (Houston and Moore 2009)
of middle to old age (Stevenson and Rutgers 2006).
The increased risk
of urolithiasis in smaller breeds is in part because they produce more concentrated urine and urinate less often than larger breed dogs Data from many
urolith analysis centres provides evidence to suggest that smaller breeds
of dog such as the Yorkshire terrier, miniature schnauzer, Shih Tzu and Pomeranian are at greater risk
of calcium oxalate urolithiasis than larger breeds.
If your veterinarian determines that your cat has
calcium oxalate or struvite crystals, the typical treatment would be dissolution or removal
of the
uroliths.
Uroliths are composed
of crystallized minerals, such as struvite,
oxalate, urate, cystine, or
calcium phosphate.
In 1981, 78 percent
of all
uroliths (aka bladder stones) tested at the Minnesota
Urolith Center were struvites (a type
of stone) and only five percent were
calcium oxalate stones.
The
uroliths have an irregular contour, which is consistent with diagnosis
of calcium oxalate.
Bladder stone (
urolith): Diagnosed via radiography, a bladder stone is a mass
of calcium and / or
oxalate salts that has precipitated into a solid mass.
These procedures can help diagnose the presence
of bacterial infection (which often accompanies bladder stones or sludge) and determine the composition
of suspected
uroliths or sludge (rabbits usually form
calcium carbonate crystals, but they may also form
calcium oxalate, ammonium phosphate, or monohydrate crystals).
Feline urinary support includes helping your cat avoid bladder infections (feline UTI), the formation
of stones (struvite
uroliths or
calcium oxalate uroliths) that might block urine from exiting the body and inflammation
of the bladder (feline cystits).
